AR15 SP-1 Bolt Carrier Group BCG Young MFG

The SP-1 Bolt Carrier by Young Manufacturing, Inc.
This bolt carrier is 1/2 oz heavier and has more surface area at the carrier front.
These additions provide improved alignment of the bolt carrier as it moves in the receiver,
tighter tolerances, more consistent bolt-lockup, and generally much smoother operation.
This bolt carrier causes less wear, improved accuracy, and overall better function.
