The 9Q-T buffer was designed specifically for suppressed guns, and also helps eliminate bolt bounce in full-auto guns.

This buffer works great in all pistol caliber ARs and is very effective in FRT/Super Safety applications. It weighs more than twice as much as standard OEM PCC buffers.

9Q-T Heavy Buffers are constructed with 303 Stainless Steel and have reciprocating Tungsten weights inside.  

None of our buffers have messy powder or fluids inside that will leak and make a mess in your gun.

The optional Adjustable Weight Kit allows the user to custom 'tune' the 9Q-T buffer to your specifc gun/ammo combination. This kit allows for a range from 5.5 oz up to 12.5 oz total weight.

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.


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).  
  • Rate of fire is generally reduced 15-25% or more. It's impossible to accurately predict ROF because of all the variables, but a 9Q-T buffer will definitely slow down your runaway train.
  • Less gas blow-back and chamber noise.
  • Smoother function, less felt recoil.

Carbine-Rifle Buffer Spacer - $15

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.
