5.56 Y/M LIGHT WEIGHT NATIONAL MATCH BCG
This carrier weighs 10.5 ounces which is .8 ounces less than our standard carrier. Added surface area in the front of the carrier gives a tighter fit when the bolt is in battery for more consistent lock up. The lighter weight results in less reciprocating mass for lower felt recoil. Also good for hunters who are trying to keep the weight down. Available in 5.56 and 7.62x39
