Xtra Heavy UCIW Ultra Compact Buffers
This extra heavy buffer weighs 5.5 oz. The extra mass helps reduce felt recoil and makes your gun operate more smoothly. Should be considered mandatory for anyone shooting hot handloads or using a suppressor.
UCIW buffers and springs are designed to work only in the LWRC UCIW/Ultra Compact Stock System.
You MUST use the LWRC UCIW receiver extension - Attempting to use these buffers in a regular rifle or carbine receiver extension will result in damage/injury/mayhem.
IN STOCK AND SHIPPING DAILY!!!
These buffers are designed specifically to complement the LWRC Ultra Compact Stock System. Manufactured in the USA by Heavy Buffers, not affiliated in any way with LWRC.
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.
Please Note: I strongly recommend using the custom spring listed here with these buffers. Some standard OEM and aftermarket springs from other manufacturers will cause issues. 'Flat-Wire' springs are not recommended in any case.
ALSO AVAILABLE: 9mm 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.
