The Rubber City Low Mass Complete BCG with Adjustable Gas Key is ideal for the 3-gun shooter or shooters who desire less muzzle movement between shots. The bolt carrier group is constructed from high-quality 8620 steel and finished with black nitride for optimal durability and strength. The carrier weighs 8.9 oz. making it much lighter than the standard M16 carrier resulting in optimal performance and making it ideal for competition. The performance of your weapon is further enhanced with the pre-hardened 4140 steel adjustable gas key with reduced sharp edges due to its radius corners. The adjustable gas key enhances performance of low mass and standard mass GI systems without unnecessary disassembly by simply adjusting the 2 set screws (one to adjust gas flow and one to lock it in place) at the carrier. The nitride 17-4 firing pin and 9310 nitride bolt offers years of service life and unrivaled durability making this a competition ready complete bolt carrier group. The Rubber City Low Mass Complete BCG with Adjustable Gas Key is ideal for the 3-gun competitor or shooter wanting better performance from their firearm.
