Universal Bolt Carrier Group with Interchangeable Weights

Abstract

A bolt carrier group includes one or more interchangeable weights that allows the user to control the weight of the bolt carrier group. One or more interchangeable weights are secured inside compartments of the bolt carrier group body such that the weight of the bolt carrier group can be changed depending on desired use of the firearm. The change in weight of the bolt carrier group allows the user to control the recoil of the firearm, the firing rate of the firearm, and the type and caliber ammunition that may be used with the bolt carrier group.
