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.
- VLTOR patented design
- Body of the buffer is 7075 T6 aluminum
- Mil-Spec Type III clear hard coat anodized
- Heaviest A5 Buffer Weight of 6.83oz
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. This item is the H4 buffer, which is normally reserved for rifles with special demands—such as on suppressed or short-barrel rifles.
