Bomb proof! - Precision Reflex Retro Carbon Fiber Forearm

I always wanted to build a Mod 0 SPR, so naturally this handguard was a no brainer. The handguard itself, and the lockup at the barrel but is incredibly robust. The long threaded barrel nut, the jam nut, the set screws that tie them all together, and then the continuous top rail make for a really rigid platform. Very impressed!
