CQB-9 buffers and springs are designed to work only in the Maxim Defense CQB Stock System.

You MUST use the Maxim CQB receiver extension - Attempting to use these buffers in a regular rifle or carbine receiver extension will result in damage/injury/mayhem.


Please Note: These products are designed specifically to complement the Maxim Defense CQB Stock System. All buffers are manufactured in the USA by Heavy Buffers, not affiliated in any way with Maxim Defense.

We machine these from solid 303 Stainless Steel and include a Stainless Steel roll pin for a lifetime of trouble-free performance. The head is polished for an extra smooth finish that won't cause damage to your buffer tube. Tungsten weights inside for maximum performance.
