Abstract: A bipod attachment mechanism for small arms that is releasably attached to an elongated rail adaptor is disclosed. The attachment mechanism removably mounts an accessory to a small arms weapon. The bipod attachment mechanism includes a rail attachment mechanism and a grip element having an upper end and a lower end, and including a hollow interior cavity. A pin-receiving section includes an aperture for receiving an accessory mounting pin, and a spring-biased catch mechanism for securing the accessory mounting pin.

Abstract: An insert assembly for a weapon is disclosed. The weapon may be a rifle, such as an M4 carbine. The insert assembly is configured to support a bolt while the bolt moves during recharging and firing cycles. The insert may be configured to continuously press on an upper receiver when the rifle is assembled. These features improve shooting accuracy of the rifle by minimizing and/or making consistent movements of the rifle's internal components (i.e., there is less wobbling of the components with respect to each other). The insert assembly may include a support plate and a hollow protrusion rigidly attached to the plate. A piston and a spring are inserted into the protrusion. The piston slides within the protrusion and is pushed against the bolt of the rifle by the spring.
