VLTOR MILSPEC EMOD A5 - The M16/AR15 Advanced A5 Stock Kit
Vltor Advanced A5 Buffer & Recoil System - This unique design of advanced buffer and new mil-spec receiver extension tube allow the A5 System to adapt a MilSpec EMOD Stock to any M16/AR15 rifle - Carbine/Midlength/Rifle/Piston.
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 a standard short 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 AND PISTON 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.
The patent pending Vltor A5 configuration stock kit is not just an EMod stock with M4 components; it’s developed as a completely new operating system. For example, the receiver extension is longer, housing a longer and specially weighted buffer, utilizing the M16A2 action spring. The A5 receiver extension features seven adjustment positions. When totally collapsed, the EMod is at the same length if mounted to any carbine length (M4) receiver extension. When totally extended (in the seventh position), the EMod can extend to a longer length of pull than an M16A2 stock assembly.
Recently tested by a professional source, the A5 system has proven to be more reliable then the M16A2, M4 and the recently released “H6” stock systems. With the use of the M16A2 action spring, the A5 system resembles the reliability and performance of the M16 fixed stock system. By having the same characteristics of the M16 fixed stock system, the A5 has shown increased accuracy and milder/smoother function, due to the constant spring rate the M16A2 spring offers. To reiterate, the A5 system offers everything the M16 fixed stock system offers, but with increased reliability and performance.
The A5 system is a superb upgrade for piston systems. Piston equipped ARs, are usually over-gassed and show excessive carrier velocities, which can lead to unreliability and decreased accuracy. As tested on numerous piston systems (such as the HK 416 platform), the A5 system has tamed such platforms and reduced the weapons rate of fire while retaining, if not increasing, the weapons reliability. Also available for the A5 system are two heavier weighted buffers for the weapon or shooter with special needs. Each heavier buffer upgrade is offered separately, but not in “kit” form.
To sum it up, all AR based platforms will benefit from the A5 system. If accuracy and reliability is what you desire, then the Vltor A5 system is what’s required!
