9Q-T Buffer Only

9Q-T Extra Weight Kit - $20

The 9Q-T buffer works great in SBRs and helps eliminate bolt bounce in full-auto guns.

This buffer was designed specifically for suppressed guns and it weighs more than twice as much as standard OEM 9mm carbine buffers.

The extra mass serves two functions:

  • 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. This in turn greatly reduces stress on the extractor and is much easier on the brass (Important for reloaders). Also helps reduce noise caused by blow-back .

  • 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 will definitely slow down your runaway train.

The optional Adjustable Weight Kit allows the user to custom 'tune' a 9Q-T buffer to a specifc gun/ammo combination. This kit allows for a range from 5.5 oz up to 12.5 oz total weight. Available only with purchase of a 9Q-T buffer. (Not compatible with standard 9Q buffers.)

NOT COMPATIBLE WITH THE OLYMPIC GLOCK MAGAZINE SYSTEM. When shooting those guns suppressed I recommend an XH Carbine Buffer (8.5oz)This applies only to the Olympic system, 9Q-T buffers work great in the DDLES & QC10 Glock lowers, as well as many others too numerous to list.

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.

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.
