Dark Storm Industries Heavy Buffer Carbine .308 4.5 oz – AR-10 Buffer

Description

Dark Storm Industries Heavy Buffer Carbine .308 4.5 oz is precision-machined to deliver controlled recoil impulse and reliable cycling in AR-10 platforms using carbine-length buffer systems. Engineered specifically for .308 rifles, this heavy buffer helps slow bolt velocity, reduce felt recoil, and improve overall system stability during operation.

Dark Storm Industries Heavy Buffer Carbine .308 4.5 oz is constructed with a 416 stainless steel machined body and internal 4140 steel dead-blow weights, the buffer is built for strength and long service life. EPDM weight spacers and a high-durometer blue polyurethane bumper reduce internal impact and component wear, while the engraved buffer face clearly identifies weight for easy system tuning and maintenance.

This buffer is designed for compatibility with select AR-10 platforms, including CMMG MK3, DPMS LR-308, and Dark Storm Industries DS-10 rifles. Proudly manufactured in the USA, it is an ideal upgrade for shooters demanding durability, precision, and dependable .308 AR performance.
