Abstract:
Bolt carrier groups (BCGs) for weapon systems are provided herein. The BCG includes a carrier assembly, a bolt assembly, and a gas chamber disposed therebetween. The carrier assembly contains a carrier body that includes a shoulder, a piston surface, and an inlet port. The shoulder is disposed within the carrier body and contains a channel and the piston surface is located on the shoulder at least partially encompassing the channel. The inlet port extends through the carrier body and is configured for receiving propellant gas into the carrier body. The bolt assembly is at least partially contained within the carrier assembly and includes a bolt head opposite of a bolt tail where the bolt tail is at least partially protruding into the channel in the shoulder. The gas chamber is disposed between the carrier body, the piston surface, the bolt tail, and two gas seals disposed on the bolt assembly.

Claim (Index 15):
A bolt carrier group for a weapon system, comprising:\n a carrier assembly comprising a carrier body, the carrier body comprising:\n a shoulder disposed within the carrier body and containing a channel therethrough; \n a piston surface located on the shoulder at least partially encompassing the channel in the shoulder; and \n an inlet port extending through the carrier body and configured for receiving propellant gases into the carrier body; \n a bolt assembly at least partially contained within the carrier assembly, the bolt assembly comprising a bolt head opposite of a bolt tail, the bolt tail at least partially protruding into the channel in the shoulder; and a gas chamber disposed between the carrier body, the piston surface, the bolt tail, and two gas seals disposed on the bolt assembly, wherein:\n the two gas seals comprise a forward gas seal and a rear gas seal, \n the forward gas seal is disposed between the rear gas seal and the bolt head, \n the forward gas seal comprises a forward chamber surface area, and \n the piston surface area is about 98% or less of the forward chamber surface area.
