Surgeon Rifles 591 Short Action Repeater Action 591 SAR

Complete short-action receiver and bolt assembly give the reliability and smoothness of the classic Remington 700 action combined with innovative features designed specifically for police, military, and civilian precision shooters. Receiver is machined, not forged, to exceptionally tight tolerances from a solid billet of 4140 chrome molybdenum steel for precise dimensions and superb strength. Raceways are EDM-cut to be perfectly square with the receiver face, threads, and bolt locking lug surfaces.

Surgeon Rifles 591

A rail in the left raceway eliminates misfeeds caused by a shell getting stuck in the raceway, and the extended ejection port ensures plenty of clearance for fired cases. Full-length, 20 M.O.A. MIL-STD 1913 Picatinny rail milled into the receiver top offers exceptional scope mounting flexibility and stays perfectly aligned with the action centerline and barrel tenon threads because it can’t work loose or get misaligned by impact. Hefty ¼” thick recoil lug machined into the underside spreads recoil force over a larger area than standard lugs. Bolt is machined from a single piece of 4140 steel billet, including .308 (.473″ diameter) breech face, extraction cam, and bolt handle; outside diameter and locking lugs are machined in a single operation, so the lugs are perfectly square with the bolt exterior. Bolt maintains a .007″ clearance out of battery, with .004″ clearance (.002″ per side) when closed. Streamlined, screw-on tactical bolt knob can be replaced with other aftermarket knobs to suit your needs. Shroud around the oversize bolt stop keeps out dust and dirt and prevents accidental release. All components are heat treated for hardness before final surface machining to prevent unwanted stress or warpage. Extractor, ejector, firing pin, shroud, and cocking piece are standard Remington 700 parts, and action accepts all triggers, stocks, and magazines compatible with the 700, greatly expanding customizing options.

All 591 actions are designed with an integral .250″ recoil lug and 20 MOA 1913 MIL-STD picatinny rail that runs the full length of the action. A side-mounted, shrouded, bolt-stop is integrated to help prevent accidental releasing of the bolt.

In the middle of the left bolt raceway is an anti-jam rail. This rail is designed to prevent a round from lodging in the raceway when single-loading the rifle through the ejection/loading port. The raceway on the right-hand side has an anti-bind rail just below the ejection/loading port. The purpose of this rail is to insure smooth bolt operation as the locking lug passes through the loading port.

The 591SA will work in conjunction with any stocks made for the Remington 700 short-action with little to no modification. It will also work with these triggers and feeding systems.

*All Surgeon Rifles™ actions are shipped uncoated and include a tactical Surgeon Rifles™ bolt knob (0-ring bolt knob shown available at additional cost).

SPECS: 4140 chrome molybdenum steel, in-the-white. Includes receiver, bolt, bolt knob, bolt stop, bolt stop pin, bolt stop spring, ejector, ejector spring, ejector pin, extractor, firing pin, and trigger pins.

Christensen Arms Carbon Remington 700 Barrel

The Remington 700 Barrel -These days Remington does a fine job manufacturing accurate rifles. However there may come a time when the old Remington 700 is not shooting groups as tight as it once did or maybe you just want the best accuracy that can be achieved from your rifle. A replacement barrel is a good investment. Its like getting a new and more accurate gun at half the price. All barrels for a Remington model 700 will be required to be fitted to some degree by a gunsmith. If you choose a barrel such as the Shilen it requires the least amount of work as it is pre threaded with a cut chamber. This means it only needs reamed to the final dimension. Other barrels are purchased as blanks and must be cut to length, threaded and have the chambers cut and reamed for your desired caliber. In many cases the barrel will require some sort of coloring or protective coating as many barrels are sold “in the white”. Note: There are no drop in barrels for a Remington 700. All replacement barrels must be fitted and headspaced by a qualified gunsmith Note: Replace your factory Remington 700 Trigger before you consider a new barrel. Visit the Remington 700 Trigger page for further information.

Shilen Remington 700 Barrels

Range time, competition wins and online reviews speak volumes. Shilen Barrels are among a small group of elite barrel manufacturers that can be considered the best of the best.

Shilen Remington 700 Barrel

Shilen Remington 700 Barrel

Shilen Select Match Grade Remington 700 BarrelThese stainless steel masterpieces of machining and hand lapping are intended for the competition shooter– or even the hunter– who wants the ultimate in accuracy and quality. These are our highest grade barrel and, of course, the most costly. What makes them so good that benchrest shooters, such as Tony Boyer, crave them? Consider this: To meet Select Match Grade criteria, the groove diameter must air gauge within .0003″ of our standard diameter. Moreover, the uniformity of the bore cannot vary more than .0001″ for the entire length of the barrel. These barrels are also completely stress relieved, and the bore is polished to a gleaming surface finish by our most experienced lappers.

Shilen Match Grade Remington 700 Barrel

Our Match Grade barrels don’t quite meet Select Match criteria– but not by much! In these barrels, the bore must measure within .0005″ of our standard diameter and cannot vary in diameter more than .0003″ for the length of the barrel. So how much accuracy does a couple of “tenths” give away, compared to our Select Match barrels? Perhaps not any! The point is, whether or not there is any real difference in the accuracy potential between the Match and Select Match grades, the really demanding shooter must play it safe and go with the higher grade. In many cartridges and barrel twists, the accuracy difference between the two simply can’t be detected. So unless you’re gunning for one-hole groups or just demand the top of the line, the Match Grade barrel is your best choice for many forms of competitive shooting and for hunting varmints and big game. The Match Grade is completely stress relieved and fully warranted. The price of Match Grade stainless steel barrels includes hand lapping to a beautifully smooth surface. Chrome-moly can be lapped to a similar finish at an additional charge. Both are available in all calibers, twists and contours.

Shilen Remington 700 barrels are pre-threaded short-chambered and crowned. Barrel exteriors are polished to a 180-grit finish, and the bores have been hand lapped. Requires installation and finish chambering by a qualified gunsmith. Technical Information Materials:Shilen barrels available in Chrome Moly Steel or Stainless Steel Production Process:

  • Match Grade:
  • Button Rifled
  • Air-gauged
  • Stress Relieved
  • Bore diameter within .0005″ of standard
  • Work Needed:
  • Requires finish chambering and headspacing to action
  • Requires external polishing and application of the finish of your choice


  • These barrels are made to the same contours as factory Remington 700 barrels.

Quality is also assured through the use of our Sheffield Air Gauge System and Rockwell Hardness Tester. Stainless steel barrels are guaranteed to be uniform dimensionally to .0001″ and free from internal tool marks. Chrome-moly barrels are uniform to within .0002″ end to end. We do not have different grades of barrels in the two types of steel: just one, our best match quality.

H-S Precision Remington 700 Bottom Metal

If you have an H-S Precision Remington 700 stock and want to convert it to a detachable box magazine the H-S PRECISION REMINGTON 700 BOTTOM METAL should be as close to drop in as possible. Non H-S stocks may require some stock inletting. It’s also important to note that H-S Precision Bottom Metal is not compatible with AICS (Accuracy International) magazines


The H-S Precision Remington 700 Bottom Metal stainless steel conversion kits are designed to convert your Remington 700 BDL hinged floor plate over to a detachable magazine box feeding system.  The external dimensions of the floor metal are identical to those of a factory hinged floor plate.  Meaning this system will fit any stock with minor to no inletting required.  The pro-series floor metal is constructed of stainless steel which is Teflon coated in a matte black finish.  It features two positive lock spring tension levers on the bottom of both sides of the floor metal.  These levers create resistance against the polymer coated boot on the bottom of the magazine box to ensure a tight fit and eliminate any rattle, whether the box is empty or full.  The new skeletonized latch located on the front front of the trigger guard works in conjunction with the robust spring to ensure a positive ejection of the magazine box every time, even with gloves on.

H-S Precision Remington 700 Bottom Metal Technical Specifications

Weight: Long action 3 round – .60 lbs, Long action 7 round – .90 lbs, Short action 4 round – .50 lbs, Short action 5 round – .60 lbs (not available in 223, 22-250, or 220 swift), Short action 10 round – .75 lbs (not available in 223, 22-250, or 220 swift)

Internal Length: Long action – 3.70″, Long action with spacer (6.5×284 or similar cartridge) – 3.10″, Short action – 2.86″, Short action with spacer (.223 or similar cartridge) -2.45″

H-S Precision Remington 700 Bottom Metal Magazines

H-S Precision magazine boxes are constructed of stainless steel, Teflon coated in a matte black finish, and feature an extremely durable polymer boot that encompasses the bottom of each mag.  The polymer boot provides a great foundation for easily installing and removing the magazine box.  We use a stainless steel follower with an extra large spring to ensure the rounds stack properly, regardless of how long you leave them loaded.  They feature a center-feed/center-stack design that allows the cartridge to be directly in-line with the chamber every time, every round.   The bolt simply has to push the cartridge out of the magazine box directly into the center of the chamber.  In traditional staggered hinged floor plate designs the cartridges must first be aligned in the magazine box before the round can be chambered, they don’t always align properly and won’t feed as reliably.  We offer 3, 4, 5, 7, and 10 round magazine boxes depending on long or short action calibers.  Another great advantage to our magazine boxes is their versatility.  The long internal length of all our boxes will allow the hand loader to optimize his accuracy even with the longest high BC bullets.  You can use one of our magazine boxes for almost any caliber simply by adjusting the feed lips.  If you have a wild cat or a pesky short mag, don’t worry, simply adjust the feed rails until they feed properly.

Remington 29663 700 5-R Military Specs .308 Winchester 24 Inch Stainless Barrel

Not appearing on the Remington website is one of their best kept secrets, the Remington 700 5-R Mil Spec.  The Remington 700 5-R Mil Spec features a Remington M700 stainless steel barreled action with a 24 inch R5 mil-spec barrel, the same barrel used in the Remington Defense M-24 sniper rifles. Barrel features a 11.25 inch twist rate with five lands and grooves and eleven degree target crown. Stock has aluminum bedding in block in standard VS configuration.

“Offering this Model 700 for ten years is a testimony to the popularity and acceptance by shooters wanting to own an exceptionally accurate rifle at a reasonable price,” states Category Manager, Dave Regula. At the core of the 700 with 5-R Rifling is the machined stainless steel, cylindrical Model 700 receiver design ensuring uniformity, strength and solid bedding area. Unique to this precision rifle is the 24-inch stainless steel, heavy barrel featuring 5-R Tactical Rifling — the same hammer-forged barrel used on the Remington M-24 sniper rifles.

Remington 700 5-R MilSpec

Remington 700 5-R MilSpec

 The 5-R Rifling barrel features five lands with a right hand twist which allows for less bearing surface on the bullet for slightly increased velocity.

As a result of less bullet drag, copper fouling in the bore is reduced ensuring long-term accuracy and consistency. The barrel is offered with a 110 target-style crown and a 1 in 11.25-inch twist.

The rock-solid barreled action is full-length, aluminum bedded into a well-designed H-S Precision stock for enhanced stability and shot-to-shot consistency. Add Remington’s X-Mark Pro® externally adjustable trigger, designed to “break-like-glass” and set at 3.5 pounds from the factory, and this rifle delivers surgical-like accuracy.

Remington M2010 Enhanced Sniper Rifle


Remington M2010 Enhanced Sniper Rifle

Remington M2010 Enhanced Sniper Rifle

Remington M2010 Enhanced Sniper Rifle (Formerly XM2010)

The Remington M2010 Enhanced Sniper Rifle (ESR), formerly known as the XM2010 and M24 Reconfigured Sniper Weapon System, is a modular sniper rifle developed by PEO Soldier for the United States Army. It is derived from the M24 Sniper Weapon System and replaced the existing M24s.

After winning a competitive bidding process, Remington was awarded the production contract for up to 3,600 weapons. The Army had anticipated fielding upgraded weapons to deployed U.S. Army Snipers near the end of December 2010,[4][5] but later expected fielding would happen in January 2011.

The M2010 system differs from the prior M24 Sniper Weapon System in that it fires .300 Winchester Magnum ammunition to provide approximately 50 percent additional effective range relative to the M24’s 7.62×51mm NATO.

This chambering to dimensionally larger cartridges is possible because the M24 Sniper Weapon System was designed to use the “long action” bolt version of the Remington 700 receiver for cartridges up to 3.34 inches (84.84 mm) in overall length.

The U.S. Army developed the system so that the additional effective range would help snipers in engagements in mountainous and desert terrain in which the War in Afghanistan was being fought.[6] The general penalties for using bigger, more powerful magnum rifle ammunition compared to smaller, standard rifle cartridges are increases in recoil, jump, flash, weight, and barrel wear.

Remington M2010 Enhanced Sniper Rifle Design

The REMINGTON M2010 ENHANCED SNIPER RIFLE differs from 7.62×51mm NATO chambered M24 Sniper Weapon System in that M2010 sniper weapons are:

  • Chambered to .300 Winchester Magnum.
  • Barreled to a 24 in (610 mm) long, 1 in 10 inch (254 mm) twist rate (using Obermeyer 5-R rifling) hammer-forged free floating barrel.
  • Fitted with a new chassis (stock) assembly that maximizes the amount of physical adjustments for the sniper to provide a better user customized fit. The chassis has a right folding buttstock that shortens the system for easier transport and better concealment during movement and accommodates the mounting of accessories via removable Mil Std 1913 Picatinny Rails and accessory cables via routing channels.
  • Fitted with a five-round detachable box magazine.
  • Fitted with a quick-attachable/detachable Advanced Armament Corporation sound suppressor with muzzle brake to reduce recoil and jump and audible and visible signature with an available thermal sleeve that reduces mirage effect on heated suppressors. The 10 in (254 mm) Titan-QD Fast-Attach suppressor eliminates 98 percent of muzzle flash, 60 percent of recoil, and reduces sound by 32 decibels.
  • Fitted with a Leupold Mark 4 6.5–20×50mm ER/T M5A2 Front Focal variable power telescopic sight featuring a 34 mm tube diameter, first focal plane Horus Vision H-58 grid system range estimation reticle and Bullet Drop Compensation,fielded with the AN/PVS-29 or AN/PVS-30 Clip-on Sniper Night Sight.
  • The application of advanced corrosion resistant coatings throughout the system.

According to Remington Arms each rifle is tested to meet (and typically exceeds) the requirement to fire ≤ 1 MOA/0.28 mrad (less than a 2-inch shot group at 200 yards) before being released for fielding.

Remington M2010 Enhanced Sniper Rifle Ammunition

In 2009 the U.S. government purchased MK 248 MOD 1 .300 Winchester Magnum match-grade ammunition for use in .300 Winchester Magnum sniper rifles like the U.S. Navy Mk13 SWS or reconfigured M24 SWSs. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 14.26 g (220 gr) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 869 m/s (2,850 ft/s) ± 15.2 m/s (50 ft/s).

According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,370 m (1,500 yd), decrease wind deflection on bullets in flight and use a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of -32 °C to 74 °C (-25 °F to 165 °F).According to JBM Ballistics, using the G7 ballistic coefficient provided by Bryan Litz, and a Weapon Employment Zone (WEZ) analysis of the XM2010 rifle with various .300 Winchester Magnum ammunition types by Bryan Litz, the MK 248 MOD 1 .300 Winchester Magnum cartridge, when fired at its nominal muzzle velocity of 869 m/s (2,850 ft/s), should have 1,286 to 1,289 m (1,406 to 1,410 yd) supersonic range under International Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m3).

In January 2014, the U.S. Department of Defense annual testing report found that the older A191 or MK 248 Mod 0 .300 Winchester Magnum service round loaded with aerodynamically less efficient 190 gr (12.32 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) bullets fired from the XM2010 demonstrated adequate performance and lethality. Live fire tests were conducted in March 2013 against ballistics gelatin, light material barriers, and other targets to determine the projectile’s ability to perforate targets. This was the first time the Pentagon’s Director, Operational Test and Evaluation (DOT&E) tested the round, which can hit targets out to 1,200 m (1,312 yd).

The U.S. Army issued three XM2010s to snipers at the United States Army Sniper School on 18 January 2011 and began using the rifle in combat in Afghanistan in March 2011. The XM2010’s .300 Win Mag round extends the engagement range over the M24 from 800 meters to 1,200 meters, enhancing lethality and standoff. The Barrett M107 .50 caliber rifle can hit targets past 2,000 meters, but it is accurate to 2.5 MOA, meaning it would hit within a 25 in (640 mm) area at 1,000 meters. This was acceptable for material targets, but not individual personnel. The XM2010 addressed the problem and gave increased range over the M24 but maintained 1 MOA accuracy. Remington had been awarded a $28 million on 20 September 2010 to rebuild 3,600 M24 rifles, but only 250 had been ordered to be changed by the time the first XM2010s were fielded.

Due to the success of the XM2010, Army officials considered a “pure fleet,” meaning all 2,500 Army M24s would be upgraded to XM2010 standard. Snipers in the field learned how to transition to the XM2010 and learn its use, maintenance, and capabilities during a three-day course. After the course, snipers had no difficulty hitting targets out to 1,000 meters from “ridgetop to ridgetop.” In addition to the more powerful cartridge, the new optic enhances the rifle’s ability to sight a target quickly without needing to do calculations of range estimation. All 250 XM2010 rifles were to be fielded in 8 Brigade Combat Teams by mid-May 2011.

Based on the results and feedback from troops, the U.S. Army decided in May 2011 to replace its entire fleet of M24s, ordering a total of 2,558 M2010 rifles. By September 2012, the Army had fielded more than 1,400 systems as part of an urgent material release. The M2010 achieved Type Classification-Standard in July 2013 and Full Materiel Release in September 2013, supporting procurement for the balance of the Army requirement. On 25 April 2014, the 2,558th M2010 rifle was completed.

Precision Guided Firearm Testing

In March 2014, the company TrackingPoint revealed their smart scope was being integrated onto the M2010 sniper rifle. The Army purchased six systems in January 2014 for testing and the networked scope and guided trigger had been added to the platform. The TrackingPoint system includes a computerized scope that marks a selected target, gathers and compensates for external factors, and uses a special trigger that does not pull until the system is sure the bullet will land where intended. TrackingPoint costs between $22,000 and $27,000 to be installed on a bolt-action rifle to achieve hits out to 1,250 yd (1,143 m), though it is not intended to replace sniping skills but be used by soldiers who need to take shots at longer sniping ranges.
