VLTOR SCAR STOCK ADAPTER
This Vltor SCAR Receiver Extension Stock Adapter is a drop-in, non-folding replacement part for the standard FN SCAR 16S or 17S factory buttstock assembly. This machined aluminum FN SCAR adapter provides a rigid platform onto which any mil-spec diameter collapsible AR-15 stock may be installed. This results in an enormous amount of options from which the shooter may choose in order to personalize the rifle to his or her individual specifications.
FN SCAR STOCK ADAPTER | VLTOR SCAR STOCK ADAPTER
The Vltor SCAR stock adapter features 6 different length of pull positions. The Stock adapter can be adjusted up and down to alter comb height for use with different sighting arrangements. Unlike the OEM stock it replaces, the VLTOR SCAR adapter incorporates a generous, o-ring sealed storage compartment inside the hollow extension tube with room to carry batteries, cleaning supplies and/or small spare parts.
For shooters who don’t use or feel the need for the side-folding capability of the factory supplied SCAR buttstock, the Vltor adapter is an excellent way to increase the gun’s modularity by outfitting it with the ability to accept many of the different AR-15 collapsible stocks on the market.
The VLTOR SCAR STOCK ADAPTER comes complete with a pair of quick detach sling swivel sockets (one on each side of the adapter block).

VLTOR SCAR STOCK ADAPTER INSTRUCTIONS
Installation of the VLTOR SCAR AR-15 stock adapter is simple, with no permanent alterations to the host rifle required.
Simply remove the factory FN SCAR stock and slide the aluminum Vltor adapter block into the receiver. Next slide the male dovetail of the receiver extension tube in from the top to engage the female dovetail of the adapter block. Finally sdjust the extension tube up or down until the desired position is obtained. Use a bullet tip or other similar tool to tighten the large locking screw on the adapter’s side to secure the tube to that location.
A Mil-Spec diameter collapsible AR-15 stock may then be installed on the extension tube in the normal fashion.
NOTE: This SCAR stock adapter is the Commercial variant, and fits Semi-Auto FN SCAR 16S (Light) and 17S (Heavy) rifles ONLY. Not compatible with select fire SCAR rifles.
Today it’s no small feat to introduce a completely new weapon platform and have it succeed in a land dominated by the AR15 and to a lesser degree the AR-10 and 308AR. FN has managed to do just that with the FN SCAR platform. While the FN SCAR might not be as modular as the at aforementioned AR-15, AR-10 and 308AR the after market upgrades from FN as well as third party sources are a testament of the platforms success. To that end FN is offering three different SCAR BARREL ASSEMBLY upgrades.

AFTERMARKET SCAR BARREL
SCAR TRIGGER GEISSELE AUTOMATICS: The FN SCAR16s, and FN SCAR17s have become commercial successes. Commercial success is no small feat in an AR15 dominant country. One of the way’s I judge the FN SCAR platform as a commercial success is the availability of aftermarket parts beyond niche manufacturers. When you see companies like Geissele Automatics who dominate the top tier lever AR15, AR10, 308AR triggers now producing SCAR Triggers and selling them at Brownells and the other usual sources, it’s time to pay attention. Unfortunately state laws prohibit me from owning a SCAR.
Geissele Super Scar Trigger
The Super SCAR Trigger by Geissele is a two-stage, semi-auto only, drop-in replacement trigger. The Super SCAR gives a clean and crisp 4-1/2 lb total trigger pull comprised of a 2-1/2 lb first stage followed by a 2 lb second stage. All components are black oxide coated to provide outstanding corrosion protection. The trigger kit comes complete with all parts, springs, lubricants and installation instructions necessary to install in any SCAR 16s or 17s.
SPECS: The Geissele SCAR has a total pull weight of about 4.5lbs – 2.5lbs on the first stage and 2lbs on the second stage. The pull weight and sear engagement are not adjustable by the shooter.
The Geissele Super SCAR trigger is a semi-automatic trigger that Geissele has developed as a retrofit for the FN SCAR 16 and FN SCAR 17. The Geissele Super SCAR trigger is designed to only fit into the standard polymer trigger housing manufactured by FN. The SCAR trigger is a non-adjustable, two-stage trigger but it is not a Match trigger. The Geissele SCAR trigger is ideally suited for Close Quarters Battle (CQB) and mid-range work. Comes with Aeroshell #6 Lubricant.
Note: The Geissele Super Scar trigger is designed to fit into the standard FN factory polymer trigger housing ONLY.

Drop-in AR 15 22 Conversion Kit:
Read the history of the AR15 22lr conversions here
The Drop-in AR15 22 Conversion Kits are the easiest and least expensive method of converting your AR15 to a .22 caliber plinker. The kits will range in price from about $160-$250 and take about 30 seconds to install. There is a few down sides to using the drop in kits. The bullet must travel a few inches in an unrifled tube before it reaches the barrel. The barrels on most AR type rifles will typically have a twist rate that is optimized for the 5.56 Nato (.223) with a 1:7″- 1:9″ barrel twist rate and not the 1:16″ that works well with .22 long rifle. There is also a few thousandths of an inch difference in the bullets diameter of .22LR (.222) vs 5.56 Nato (.224). Those differences can lead to less then match grade accuracy in an AR15 but the accuracy is perfectly suited for plinking. If that accuracy is not suitable you can purchase a complete .22 long rifle upper. The cost starts at about double of the drop-in conversion and can go upwards well over $1000. The choice is yours.
I purchased my Colt brand conversion kit part# R6222 back in the early 90’s without much fanfare. The Colt and the Jonathan Arthur Ciener kits seemed to be the only ones around at the time, at least that was my findings in the Shotgun News and prior to the internet. Recently a good friend purchased his first rifle, a Bushmaster Modular Carbine. I explained to him the virtues of cheap practice ammo, getting to know the rifle and the ability to shoot at any indoor range. Eager to get a conversion kit he quickly hit the web with google and met a brick wall in a lack of availability. My friend got quickly frustrated so I decided to do some research the result of which you are reading here. A few things came to light very quickly. The Colt unit I own while listed as a current product offering is nowhere to be found. The Jonathan Arthur Ciener kits are being offered at several places for low prices but none are in stock even at his own site .22lrconversions.com. Jonathan Arthur Ciener has always had a long back order and a history of poor customer service. He also has quite a few complaints against him at the BBB. In fairness everybody seems to get their kits just be prepared to wait. In the end my friend ended up ordering a CMMG AR-15/M16 22LR BRAVO CONVERSION KIT from Brownells Update 2015:(When this article was originally written the word “Bravo” was not part of the name
.22 Caliber AR Upper Receivers
Now if after reading the above you feel you need more from a .22 conversion a complete upper chambered for .22 long Rifle is exactly what your looking for. You will be able to achieve greater accuracy and superior reliability with these dedicated uppers. These units start at around $450 with the sky being the limit. The low end units typically will look like any other AR15 with a typical handguard and a carry handle or flat top receiver. What starts to drive the costs way up is the barrels. Some manufacturers offer custom match grade barrels. These barrels turn the AR15 into a fine precision shooting machine with accuracy on par with other top rifles in the .22 Long Rifle class. Take a look at this Lakeside Guns for what is probably the most radical 22lr AR-15 dedicated upper receiver to date.
- Keep the drop-in units cleaned and lubricated
- Inspect the gas tube for fouling before returning the weapons center fire bolt carrier.
- If you get failures to extract often, clean the area under the extraction claws. It has probably become dirty and the claws are not returning to their fully retracted position
- Failure too feed will be from the magazine and or carbon buildup on the neck of the carrier preventing it to fully seat in the chamber
- Failures to fire, see above. The carbon prevents the the .22 bolt from seating firmly. Energy is lost from the firing pin and light strikes can result
- Ammo – These things can be fussy and cause either of the two previous problems. I’ve found high and hyper velocity ammo to work best.
How easy is it to install a .22 long rifle AR-15 Conversion kit?
Brownells has put together a video presentation display how easy it is to install the CMMG Conversion Kit
CMMG AR 15 .22 Hardware AR 22 CMMG AR15 22 Conversion Kit
August 22, 2010 – CMMG is growing their .22LR line up by leaps and bounds. They have added Stainless Steel and Left Handed versions of their popular AR-15 conversion units as well as dedicated .22LR Uppers and Complete Rifles ,22LR. There are also many more models to be released over the next few months. CMMG is also adding accessories unique to these .22’s as well as possibly firsts in the shooting world. The first item is the Anti-Jam Charging Handle for Drop-In Conversion .22. The charging handle is machined much more shallow that that of an AR-15. This prevents a .22 case from getting jammed inside the upper.

The other items are hardware to enable the last shot hold open feature of an AR-15 to function with any Atchisson based .22 conversion unit.

This is the brand new CMMG .22 Long Rifle AR15 Conversion Kit. The kit includes the conversion unit and either a 10 or 27 round magazine. The magazines are manufactured by Black Dog Machine LLC.
CMMG .22LR Conversion
Range Report: We received our CMMG kit approximately 2 weeks after ordering it directly from CMMG. The unit was well made and fit our brand new Bushmaster Modular Carbine perfectly. A quick trip to an indoor range for some informal shooting and we were very pleased. We put 300 rounds of inexpensive Federal American Eagle .22 through the Bushmaster with only one failure to fire. The rim of the cartridge was struck firmly so I fault the cheap ammo and not the conversion kit. Feeding and extraction were perfect with no failures. Accuracy was better then we expected at 25 yards with the Bushmaster sporting a 1-4x Millet DMS Scope. Shooting from a bench we could easily blast out the blast out a 1″ circle all day. The kit is probably capable of better accuracy then that but the trigger on the Bushmaster is a little stiff. We will compile a real review at a later date.
Order the CMMG .22 Long Rifle AR15 Conversion Kit from Brownells for $239. Brownells stocks the 10 and 27 round magazines for the kits

CZ V22 .22 Conversion
The V22 Complete upper receiver made by CZ, aluminum alloy receiver, 16.25″ carbon steel barrel, black finish, super quality, see American Rifleman P.64, March 2005.

May not fit some later production Colt Rifles, fits all the other Clones we have tested. This is NOT a complete rifle, just the upper forward assembly which allows you to convert your existing rifle to the .22-LR caliber.
I found this product description on a web site that used to offer the V-22
Get set for some serious fun with our new AR-15 .22 LR conversion! Make no mistake, this is NOT the cheap “blowback bolt and insert kit” offered by others (please read our warning about those): ours is a purpose built, precision machined assembly that replaces your entire upper, thus eliminating the problems experienced with discount-priced “kits” that use your existing upper and .223 Rem./ 5.56x45mm barrel.
In our continuing quest to bring you the best value for the money we have chosen Ceska Zbrojovka (CZ), whose long-established reputation in manufacturing quality sporting and military firearms is second to none, and imported their V-22 .22 LR AR-15 system. These complete .22 LR “uppers” boast all the latest features: hammer forged 16” heavy barrel, free-floating knurled hand guards, flat top receiver with integral weaver base, picatinny rail, and more!
You can also choose whatever configuration best suits your needs: just the complete CZ V-22 system itself, the complete V-22 with detachable carry handle, or – as an introductory limited time offer – the complete V-22 equipped with 4x28mm AR-15 scope with bullet drop compensator!

Bushmaster Carbon 15 .22 Rimfire
Bushmaster offered a .22 Rimfire dedicated Upper Receiver/Barrel Assembly that will fit all Bushmaster Lower Receivers – as well as most all AR15 Type Lower Receivers from other manufacturers (as long as they are mil. spec in measurement. With an Upper specifically designed for .22 Rimfire, you can quickly switch out from your 5.56mm/.223 caliber Upper to hone your shooting skills with the economical .22 Long Rifle ammunition – which is acceptable at most indoor ranges due to its lower power and penetration. In addition to offering the advantages of more frequent training with your AR15 type rifle, the Bushmaster .22LR Upper adds versatility to the weapon system, and is a joy to use for plinking.
The light weight and low recoil will be appreciated by women and younger shooters. The Bushmaster .22LR Upper Receiver/Barrel Assembly is a complete kit which includes all pieces necessary to quickly convert your rifle over to .22 Rimfire. The Upper Receiver is chambered for .22 Long Rifle only, and operates in a semi-automatic “blowback” mode. Other parts of the kit include a 10 Round Magazine; a Recoil Spring and Buffer; and a Butt stock Insert which acts as a guide for the Recoil Spring and replaces the standard AR Buffer and Action Spring inside the Receiver Extension.
The highly accurate 16″ Barrel is rifled 1 turn in 16″ for the .22 LR cartridge, and is machined of Chrome Moly Barrel Steel. A “blowback” operating bolt is machined from lightweight aluminum for great durability, and all parts are easily disassembled for cleaning / maintenance. The iron sights of the .22LR Upper feature a dual rear flip aperture (adjustable for windage), and a square front post type sight adjustable for elevation. On the Upper Receiver, a Picatinny rail offers easy mounting of any scope, optic, red dot or laser sight.

Compass Lake CLE AR22
Here’s a little info from the Compass Lake web site. “We use the Army’s M-261 kit because it has proven to be the most reliable of all the kits we tested. The M-261 kit will allow single loading as the bolt will lock back after each shot when used with a standard .223 magazine. The M-261 magazines are insert magazines that fit into a standard .223 magazine. The bolt will not lock back automatically on the last shot with the .22 insert magazine installed. The bolt can be manually locked back with either. The upper receivers are supplied with two magazines and one single round loading device (LED). This device enables you to insert a single round into the chamber to make it possible to single load the rifle.
We use Douglas stainless steel 1-16 twist rimfire barrel blanks. The cartridges chamber directly into the barrel. The chambering reamer is a JGS match reamer that is very similar to the Bentz reamer. The service rifle uppers are equipped the same as our .223 service rifle uppers with float tube and 1/2 moa or 1/4 moa match sights with interchangeable apertures and hood. Most shooters choose the 1/4 moa rear sight for the fine adjustment it offers. Space gun uppers are also available either in flat top/A4 or modified receiver configuration. Krieger rimfire barrels are available for an additional $112.20

The original DPMS conversion kit is the same as the Colt unit. It is no longer available. I cannot seem to locate if DPMS is currently offering a kit but they is offering complete uppers
DPMS CMP22LR AR 15 22
Based on my research DPMS made at least two different dedicated .22lr upper receivers. From the images Ive seen they look very good and appear to utilize the Colt style magazine and modified Colt bolt carrier. This would make sense as mentioned above DPMS once offered a DPMS branded Colt 22lr conversion for sale.

SPIKES TACTICAL .22LR CONVERSION UPPERS
Spikes Tactical offers a few different variations of complete upper receivers as well as .22 LR conversion kits. The conversion kits look to be similar to the CMMG and Ciener units. Differences: notice the o-rings for a better chamber seal and chrome plating for smoother function and easier cleaning. The Spikes unit cost more then the competitors but its worth the premium in my opinion.
Something that sets Spikes Tactical apart from the others is they offer the parts to build your own .22 LR AR-15 starting with a caliber stamped “.22 long Rifle” stripped lower receiver. Pretty unique.
