Abstract: The present invention is a modular stock system for rifles. The system replaces the rifle's buffer tube with a modified one containing a mount for a constant cheek weld and a rail track for adjustment. A stock module then mounts on the replacement buffer tube. The stock module is interchangeable depending on the user's needs. Various configurations of the stock module are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The stock module may be made even further modular by the addition of rail system.

Abstract: The disclosed invention is a rail cover for use on mounting rails typically, though not exclusively, used on personal firearms. The covers may be made to fit either Picatinny or Weaver type rails and feature a clipping structure on the cover's underside that grasps the rail while the tension in the cover body holds the cover in place. Two preferred embodiments disclose a solid cover and a low profile, ribbed cover that nests within transverse grooves in some rails. Alternatively, a restraining beam may be utilized to further restrain the clipping structure and retain the cover on the rail.

Abstract: A digit support for AR family receivers designed to reside in a gap left between a receiver's pistol grip and trigger guard. The support fills the gap and ideally separates a user's digit from the gap, thereby protecting the user's digit from injury due to prolonged contact with the walls forming said gap. The digit support is easily installed without removal of any components of or attachments to the receiver and in its best mode allows for the simultaneous opening of the receiver's trigger guard. In the best mode, the support is a body molded from a rubber compound having dimensions to fit snugly in the gap left between the trigger guard and the pistol grip. Ideally, the remaining exposed surface extends slightly higher than the depth of the gap and is cylindrically domed. Also in the best mode, the side of the body abutting the trigger guard mount should have a concavity designed to fit around the trigger guard mount so as to encompass said mount.
