Abstract: The present invention relates to systems and methods for aiding the insertion of detachable magazines in AK rifle variants. The magazine well attachment includes a well attachment body having a slit configured to slide over a trigger guard of a firearm during the assembly process. The attachment body includes a beveled well opening for guiding a tilt-lock magazine into the firearm. The beveled well opening includes beveled steps for funneling and centering the magazine during insertion and also includes an angled front well ramp for guiding the magazine into the rifle at an appropriate angle. In order to accommodate the dimensional variances between receivers made by different manufacturers, a front retainer secures the attachment to the magazine opening. The magazine well attachment also includes a rear overhang secured to a ledge of the firearm's trigger guard.

Abstract: Systems and methods for using a cartridge case as a tool to install or remove firearm barrel attachments. The barrel attachment includes a channel for engaging a cartridge case rim. This rim channel provides mechanical leverage for rotating the barrel attachment around a bore axis of the firearm barrel. The rim channel may include a curved portion to increase the load-bearing contact area. The contact area between the rim of the cartridge case and the barrel attachment can be further increased by a half-moon insert.

Abstract: The present invention relates to systems and methods for using a cartridge case as a tool to install or remove firearm accessories such as a barrel attachment. The barrel attachment includes a coupling section for attaching the barrel attachment to a firearm barrel. The barrel attachment also includes a rim channel for engaging a portion of the rim of a cartridge case. This rim channel provides mechanical leverage by enabling a user to apply force on the engaged cartridge case to rotate the barrel attachment around a bore axis of the firearm barrel. In some embodiments, the rim channel is an integral portion of a cartridge rim slot machined into the exterior part of the barrel attachment. Ideally, the rim channel includes a curved portion to increase the load-bearing contact area. The rim channel can also be adapted to accept different case rim sizes. Multiple rim slots can be machined into the barrel attachment, allowing the user to spread out the forces amongst multiple cartridge cases.

Abstract: A method is provided for the reduction of inflow of rock particles from an earth formation into a wellbore for the production of hydrocarbon fluid. The method comprises creating a zone of reduced compressive stiffness around the wellbore by removing rock material from the wall of the wellbore.
