Abstract: A stock has a buttstock. The buttstock includes an adjustable comb. The comb is connected to a body of the buttstock via a rod extending into the body of the buttstock and movable along a first axis. The position of the rod and comb is locked and unlocked by a latch. The buttstock includes an adjustable recoil pad. The recoil pad is connected to the body via a threaded rod mated with a nut embedded within an end of the body. The threaded rod and recoil pad move a direction along a longitudinal axis of the body depending on the rotation of the nut.

Abstract: A charging handle assembly for a rifle has a body extending along a first axis. The body comprises a first side, a second side oppositely disposed, and an opening therebetween. A first handle is connected to the first side and extends away from the body along the first axis. A second handle is connected to the second side and extends away from the body along the first axis. A rod, comprising a first end and a second end, extends through the opening along a longitudinal axis oriented transversely to the first axis. A return spring acts between the body and the first end of the rod and biases the body towards the second end of the rod. The body is movable between the first end and the second end of the rod and compresses the spring when moving towards the first end.

Abstract: A firearm having a fixed magazine uses a latch to secure upper and lower receivers to one another in a closed position. The upper and lower receivers can be pivoted relatively to one another into an open position providing access to the magazine for loading by rotating the latch to release the upper and lower receivers from one another. The latch includes a hook spring biasing a hook contact surface of the latch to engage a hook receiving surface of a receiver when the receivers are moved from the open position to the closed position.
