Publication number: 20130180146Abstract: A new interface for a magazine follower and floor plate is used to provide greater stability to the round stack and a more sturdy system overall. The floor plate is designed with two opposite legs, the rear being shorter than the front leg so as to facilitate travel throughout the magazine and clearing of accumulated dirt and debris. The floor plate, in one embodiment, utilizes a lock plate that is shaped and sized to become a shoe for the compressed spring and associated follower. In an alternate embodiment, the floor plate itself serves the purpose and, with provided teeth, directly fastens to the magazine casing at notches manufactured in the magazine wall for that purpose. Other enhancements to the magazine include at least one matrix of divots to provide a paint surface, an over-insertion stop and a lower rear geometry to aid in clearing debris and grit.Type: ApplicationFiled: January 17, 2013Publication date: July 18, 2013Applicant: Magpul Industries Corp.Inventors: Richard M.

Publication number: 20120317857Abstract: The present invention is an ammunition magazine, preferably made of a reinforced polymer, utilizing a structurally enhancing ridge, angular guide rails and a follower made to interface with said guide rails to reduce wobble. The preferred embodiment also features a protective cover that distributes forces from the spring to more structurally sound areas of the magazine, thus reducing feed end splay, and an ammunition indication system comprised of at least one window and a noticeable marker on the follower spring. The follower and magazine casing are also designed to interface to prevent the follower from popping out of the feed end and the floor plate of the magazine utilizes a locking plate and sliding relationship between the floor plate, locking plate and magazine to secure the floor plate onto the magazine casing. The cover features built in tools for, among other things, unloading and disassembling the magazine.Type: ApplicationFiled: November 30, 2011Publication date: December 20, 2012Applicant: MAGPUL INDUSTRIES CORP.Inventors: Richard M.

Patent number: 8307747Abstract: A non-reciprocating, self-engaging charging handle is disclosed. It comprises a spring biased forward latch mounted upon a sliding body with a protruding handle. The spring bias causes the latch to positively engage the firearm's bolt carrier group when the handle is brought forward into contact therewith. A secondary latching system secures the charging handle to the upper receiver when not in use and disengages automatically when and only when a user desires to operate the handle.Type: GrantFiled: January 19, 2011Date of Patent: November 13, 2012Assignee: Magpul Industries Corp.Inventors: Richard M.

Patent number: 8006425Abstract: The present invention is a spring-biased folding firearm that stows compactly and safely. The firearm has three main components: a stock, a receiver and a grip/magazine combination. In folding, the stock folds over the receiver, sandwiching the grip/magazine between the components. When folded, the magazine over-inserts into the grip housing, allowing the stock to clear and providing additional safety when stowed by isolating the ammunition feed. A buttplate latches over the open joint to contain the unit and further secure it. When stowed, the bolt is disengaged from the ammunition feed supply, preventing accidental firing, so a loaded round can be safely carried in the chamber—allowing for immediate use of the firearm upon opening. The weapon is deployed through single-handed actuation and is spring-assisted into firing position. Currently the firearm uses readily available aftermarket parts for easier replacement if necessary and does contain hardware for mounting accessories.Type: GrantFiled: April 7, 2009Date of Patent: August 30, 2011Assignee: Magpul Industries Corp.Inventors: Eric C.
