Benefits of technology

This patent is about improving the trigger finger guide and bolt catch structure of a firearm. The invention aims to enhance tactical advantage, firing accuracy, and firing speed. The improvements in the bolt catch structure make it easier to install and remove the mounting pin, resulting in faster assembly and disassembly. Overall, this invention provides a better firearm design for better performance and ease of use.

Problems solved by technology

Remote relocation of the trigger finger is a tactical disadvantage and effects firing accuracy and speed.
Moreover, heretofore known lower receivers have all included structure that impedes bolt catch assembly installation, and in particular that makes bolt catch roll pin installation and removal a tedious and slow process.

Embodiment Construction

[0029]The improved lower receiver 15 of this invention is illustrated in the FIGURES. FIGS. 1 and 2 show lower receiver 15 in various stages of assembly with other component assemblies of firearm 17. Firearm 17 (as shown herein, an AR-15 type of semi-automatic firearm that is well known in the art) typically includes an upper receiver 19 connected with lower receiver 15. The receivers are made of metal or other materials known for such application using well know manufacturing techniques (milling, molding and the like).

[0030]Upper receiver 19 is adapted for connection of the upper assemblies of firearm 17 thereto (including barrel 21 and handguard set 23, for example) as is well known. Lower receiver 15 is adapted for connection of the lower assemblies of firearm 17, including user interface assemblies 25 and 27 (a pistol grip assembly and a stock assembly, respectively, the stock assembly including the buttstock and buffer tube), magazine 29, magazine catch assembly 31, bolt catch ...

Abstract

A lower receiver for a firearm is disclosed that includes a trigger and hammer assemblies receiving section and a magazine well section, a raised bolt catch mount and a trigger access opening defined between the sections. The bolt catch mount includes an opening for insertion of a bolt catch mounting pin, a pin insertion relief formed at the magazine well section aligned with bolt catch mount opening. A trigger finger guide feature is defined between the trigger access opening and the magazine well section below the bolt catch mount.

Description

FIELD OF THE INVENTION[0001]This invention is related to firearm assemblies and, more particularly, relates to lower receivers for firearms.BACKGROUND OF THE INVENTION[0002]Semi-automatic firearms are in wide use. Lower receivers for firearms (in particular semi-automatic firearms such as the AR-15) are used to accommodate firearm assembly and deployment and are well known and also widely utilized. A trigger assembly as well as other components are received at the lower receiver.[0003]When not firing, a user of the firearm must learn to remove the trigger finger to a position remote from the trigger to prevent accidental firing which may occur when the finger is left on the trigger. Remote relocation of the trigger finger is a tactical disadvantage and effects firing accuracy and speed. Several solutions have been suggested for various firearms, though none are completely satisfactory (see U.S. Pat. Nos. 8,474,169 and 6,023,874, as well as U.S. Pat. No. 7,786,397 suggestive of anoth...
