9mm-Q Buffer Only

The 9-Q is the original extended-length AR9 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. 

9-Q Heavy Buffers are constructed with 303 Stainless Steel and have reciprocating steel weights inside.  None of our buffers have messy powder or fluids inside that will leak and make a mess in your gun.

This buffer is compatible with virtually all manufacturers.  Any PCC will benefit from upgrading to a 9-Q Heavy Buffer.  

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

This buffer is for use with 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. We also make custom A5-length PCC buffers - Email for more info.

Also available for FRT/Super Safety and suppressed guns: 9Q-T Tungsten Buffer


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.

Quantity:      


This product allows you to use a carbine-length buffer and spring in a rifle-length stock/receiver extension. For AR15 applications only.



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.

Specifications are subject to change without notice.
