9mm-Q Buffer Only

The 9-Q is the original extended-length 9mm buffer, engineered from scratch in Ohio, USA - Not a cheap imported knock-off.  Field tested and proven for over two decades!

We developed the 9mm "Q" Heavy Buffer in response to a customer who was having a problem with broken bolt catches on his Colt 9mm rig. He was already using a special (more expensive) buffer, and his gun was still breaking bolt catches on a regular basis. We isolated the problem and designed this buffer to correct the flaw. With Colt 9mm bolt catches running $25+ each, a 9-Q Buffer is cheap insurance against future problems. 

We manufacture the heaviest 9mm buffers available anywhere. Increasing buffer mass has many benefits:

  • Rearward movement of the bolt (and thus extraction) is slightly delayed.  This fraction of a second allows the brass to 'shrink' back to it's normal size, greatly reducing stress on the extractor and brass damage (important for those that reload their ammo).  
  • Smoother function, less felt recoil.
  • Less gas blow-back and chamber noise.
  • Reduced rate of fire.

9-Q Heavy Buffers are made of 303 Stainless Steel and filled with solid steel weights.  Our buffers don't have messy powder or fluids that can leak and make a mess inside your gun.

The 9-Q Heavy Buffer was specifically designed and tested for use with Colt 9mm ARs, but is compatible with virtually all manufacturers.  Any pistol caliber carbine will benefit from installing a 9-Q Heavy Buffer.  

We suggest using Wolff XP buffer springs for maximum reliability. Flat wire springs are not recommended.

This buffer is for carbine-length stocks only, the spacer below is required for use with rifle-length stocks. When used with a spacer you'll need a carbine buffer spring.

Also available for suppressed weapons: 9Q-T Tungsten Buffer

Note: We cannot guarantee proper function with subsonic ammo. There are significant differences in specifications among the various brands of ammo and firearms manufacturers. Some guns will run great with almost any ammo, other guns may not function reliably with any subsonics. This is all beyond our control.
