Vltor A5 Standard Weight Buffer - 5.3 Oz.

The VLTOR A5 buffer system is one of the most tried-and-true buffer systems available in the AR-15 world today. The A5 buffer was specifically designed at the request of the Marine Corps to bring an adjustable stock to their 20" M16 rifles. VLTOR brought them a completely new buffer system that used a rifle-length spring in an adjustable receiver extension tube. This translates to a smoother, slower bolt movement that reduces felt recoil and allows shooters to keep on target. Note: This buffer does not fit standard carbine extensions. This buffer is only compatible with rifles and pistols utilizing the VLTOR A5 Buffer System and receiver extension. Features: VLTOR patented design Body of the buffer is 7075 T6 aluminum Mil-Spec Type III clear hard coat anodized Middle A5 Buffer Weight of 5.33oz A5 buffers can only be used with the A5 receiver extension and come in 5 different weights, depending on the needs of the user. Most 16" AR-15s will use the lower weight H1 and H2 options. Short-barreled rifles or suppressed rifles, which experience a lot of backpressure, use H3 and H4 heavy buffers to counteract the violent action of the AR-15's bolt. Always check with your rifle's manufacturer specifications to determine what weight is appropriate in your firearm. In special cases, additional research may be done online to determine compatibility.
