Product Description

Vltor A5 Buffer & Recoil System - The unique design of the new buffer and receiver extension tube allow the A5 System to adapt a MilSpec EMOD Stock to any M16/AR15 rifle.

Tests show that the A5 System reduces the cyclic rate of the M4 Carbine and lowers bolt carrier velocity; and recently, extensive testing conducted on the M16A4 proved that the A5 System was the most reliable and consistent stock system available for that platform!

The A5 Buffer and Recoil Assembly was developed by Vltor Weapons for the specific needs of the U.S. Military. As the M16/AR15 series of rifles have evolved into specialized configurations, such as the SPR, M4 and Mk 18, each of these designs using a new combination of barrel and gas-systems. Attempts to universally use the standard collapsible stock on all platforms - from M16A4 to the Mk18 - have proven unreliable at best.

The A5 Buffer and Recoil System takes a new approach to this problem, providing a single collapsing stock and buffer system that can be used on all current configurations of direct impingement systems. The A5 System reduces cyclic rate on the shorter barreled rifles and maintains a much more consistent bolt velocity and rate of fire across all current issue weapons based on the M16.

  1. 6.5 Grendel shooters' best friend

    Posted by Jack on 8th Oct 2011

    6.5 Grendel uppers are great, but what many don't realize if they don't do their homework is that they can get a little unreliable with standard carbine buffer assemblies (this is confirmed by Bill Alexander as well) and sometimes need to "break in." Hearing this, and then researching the problem, I purchased an A5 system for my selected lower. From the first shot fired the carbine not only cycled 100% reliably with the A5, but when I switched the upper to a standard lower (with carbine buffer assembly), I got occasional stovepipes, double-feeds and the felt recoil was noticeably greater. Well-researched and designed, I've used the A5 with both 5.56 and 6.5 Grendel platforms with solid performance and no malfunctions. Excellent job, VLTOR.

  2. Vltor A5 System another winner.

    Posted by W.Larson on 8th Jun 2011

    I have been shooting the AR platform for almost 25 years. I have used various configurations in the military and as a contractor overseas to include work as an armorer. I have been using my Vltor A5 set up on my 11.5" SBR with an AAC M4-2000 suppressor for a few months now. The recoil impulse is much different than the previous set up using a carbine extension and H3 buffer. It is very smooth and consistent. I have also installed it on midlength AR's and again it functions as advertised. If you are truly looking for a universal system that can be used on various AR configurations this is the set up to get and it is well worth it.

  3. Nice!

    I recently became a fan VLTOR accessories and built an AR using all available VLTOR parts including the A5 system... I built the upper using a 16" BCM midlengh barrel and using the A5 system is a perfect match! At 100yds using 62grn 556 I remained on target with a ridiculous smooth recoil! The EMOD stock is really nice with a very comfortable cheek rest... The battery compartments on the cheek rest are cool, I use the extra compartment on the clb ft area for a small scope cloth and some L keys for accesories... I recomend the A5 system to all my buddies and plan on using one for an AR-10 build

  4. It works great!

    Posted by JohnnyRambo - Calegalmags.com on 19th Feb 2011

    As a retailer I try everything I sell so I can be sure that I am only selling quality parts and components.
    This weeks new product was the A5 Emod Stock System. It performed flawlessly. Smooth cycling, and very little recoil. Not a single malfunction of any sort. I give it my stamp of approval and will be happy to sell it to my customers knowing that it works as advertised, if not better.
    VLTOR continues to release top quality products!
    (Tested on DD 16" upper w/ mid gas system)

  5. A5 reciever extension kit

    I recently tested the A5 kit using the standard weight buffer on rifles from 10.5-20" and it performed just as advertised. It softens the recoil via the heavier weights and longer travel and will run on any configuration from 10.5-20". If I were outfitting an agency or department I would begin the transition to the A5 so any lower will be capable of reliably accepting any properly built AR type upper.
    I will begin to transition to that in all but the rifles I want max compactness from (8.5-11.5" SBR's)
