Strike Industries SMC Billet Stock - Carbine Buffer System Compatible

The Strike Industries SMC-BS-H (Strike Mass Carbine - Buffer System Heavy) delivers enhanced recoil management and improved cycling reliability for AR-15 platforms. This precision-engineered buffer system reduces felt recoil while maintaining consistent bolt carrier group operation across various ammunition weights and shooting conditions.

What Makes This Different

Unlike standard carbine buffers that rely on basic steel weights, the SMC-BS-H incorporates tungsten powder fill technology for optimal mass distribution. The buffer weighs approximately 5.4 ounces compared to standard 3-ounce carbine buffers, providing 80% more mass for superior recoil dampening. Internal dampening technology reduces bolt bounce and carrier velocity spikes that can cause premature wear on upper receiver components.

Key Features

• Heavy tungsten powder fill construction for maximum recoil reduction
• Precision-machined 7075-T6 aluminum body with hard anodized finish
• Compatible with standard carbine buffer tubes and springs
• Reduces bolt carrier group velocity by approximately 15-20%
• Internal shock absorption system minimizes receiver stress
• Works with 5.56 NATO, .223 Remington, and .300 Blackout chamberings
• Mil-spec dimensions ensure drop-in compatibility

Field testing demonstrates consistent cycling with both lightweight 55-grain varmint rounds and heavy 77-grain match ammunition. The increased buffer mass particularly benefits suppressed configurations where back-pressure can cause over-gassing issues. Competition shooters report faster follow-up shot acquisition due to reduced muzzle rise, while the system maintains reliability in adverse weather conditions including temperature extremes from -20°F to 140°F.
