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
  • Middle A5 Buffer Weight of 5.33oz
  • Works great when combined with Sprinco GREEN Buffer Spring

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.

    These are the best. Changing all my ars to this.

  2. Rodger Craddock (verified owner)

    Perfect buffer for my SOLGW 13.7 when paired with the Sprinco Green buffer spring. Soft recoil impulse and 3-4 o’clock ejection suppressed and unsuppressed.

    Once you run an A5 buffer system it’s hard to go back.

  4. Christopher Rausch (verified owner)

    Gradually converting all my 5.56 guns to the A5 buffer system. Improves performance and recoil, and the H2 will drive pretty much anything, suppressed or unsuppressed. Don’t know why this isn’t the standard system on AR’s.

    Don’t skimp on your guns. Go with the A5 setup
