This Heavy Buffer helps eliminate many common reliability issues - especially those related to running a suppressor, FRT (Forced Reset Trigger), Super Safety, or SBR. Also helps prevent bolt catch damage/failure.

We start with solid 303 Stainless Steel and add reciprocating Tungsten weights for the "Dead-Blow" effect. None of our Heavy Buffers have messy powders or fluids inside that will eventually leak (they always do) and muck up your gun's internals.

U-9 buffers and springs are designed specifically to complement the LWRC UCIW/Ultra Compact Stock System on pistol caliber carbines. Not compatible with CMMG radial delayed blowback guns or any rifle calibers.

You MUST use the LWRC UCIW receiver extension (6" internal length) - Attempting to use these buffers in a regular rifle or carbine receiver extension will result in damage/injury/mayhem.

Please Note: We strongly recommend using& the custom spring listed here with these buffers. Most springs from other manufacturers will inhibit proper function. 'Flat-Wire' springs are not recommended for any application.

Manufactured in the USA by Heavy Buffers, not affiliated in any way with LWRC.


ALSO AVAILABLE - 5.56mm UCIW BUFFERS

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.
