The 77gr REX features a new advanced technology bullet that expands at subsonic velocity.  The projectile is manufactured by Maker Bullets on state of the art CNC equipment.  This is the best .223 Subsonic round available for hunting or defense work.

Beck Ammunition Silent Operator™ series is engineered to run at Subsonic Velocities (just below the speed of sound) and to be shot with a sound suppressor.  This is the most deadly 77gr Subsonic ammunition on the market.  This ammunition is designed to be shot suppressed (Silencer) and truly is "Hollywood Quiet."  It is engineered for optimal subsonic velocity using a 16" barrel, but shoots great through most 20" barrels as well.  With a proper sound suppressor, this ammunition sounds very close to a pellet gun. The fact that this subsonic ammo does not cycle in a semi-auto makes it the ultimate stealth round because keeping the bolt closed makes all the sound go through your suppressor. This ammunition also serves as a reduced recoil round for those with physical disabilities and desire less felt recoil.  Manufactured with new Starline brass.
