The TacFire MAR045 Heavy Buffer Black Aluminum/Steel AR10 is a purpose-built recoil buffer designed for .308 AR-10 pattern rifles. Machined from a durable aluminum body with steel internal weights and finished in black anodizing, this 3.8 oz heavy buffer helps smooth out cycling and manage the sharper impulse of full-power rifle cartridges while maintaining reliable operation in compatible AR-10 buffer systems.

This heavy buffer is ideal for shooters looking to fine-tune an AR-10 for more controlled recoil and a steadier sight picture during rapid strings at the range or in training. By adding mass and refining the movement of the bolt carrier group, it supports more comfortable shooting and consistent performance with .308 Winchester loads. TacFire’s attention to detail and proven component design make this buffer a straightforward upgrade for AR-10 builders and enthusiasts.
