Publication number: 20230304770Abstract: The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot.

Patent number: 11085723Abstract: This disclosure describes systems, methods, and apparatus for a firearm grip module having a selector track arcing concentrically around a selector lever aperture in one of two walls of the firearm grip module. The selector track can include multiple levels or heights, corresponding to different operating mode positions of the selector lever, where these different heights cause differing resistance to movement of the selector lever, where greater height equals greater resistance. The selector track may also include a safety indentation, a semi-auto indentation, and a full-auto indentation. The track may also include a removable, molded-in stop, between the semi-auto and full-auto indentations, which blocks the selector lever from overtraveling a standard fire position.Type: GrantFiled: April 26, 2019Date of Patent: August 10, 2021Assignee: Magpul Industries Corp.Inventor: Nicholas Kielsmeier
