Apparatus and methods for optimizing direct gas operated firearms

Abstract

Apparatuses and methods are provided for an optimized direct gas operated firearm. The firearm includes an upper receiver coupled with a lower receiver by a tensioning screw that reduces wobble between the upper and lower receivers. A barrel extension is configured to eliminate misalignment during installation into the upper receiver. A bolt carrier includes a reinforced bolt assembly and a forward-biased dwell weight. The bolt assembly includes an extractor and an extractor pin that simplify disassembly of the firearm. A handguard includes locks that attach to a barrel nut area of the firearm. The locks clamp onto the barrel nut area to align the handguard with the upper receiver. An ambidextrous bolt catch release assembly is operable from either side of the lower receiver. A bolt catch release paddle is disposed at the front of a trigger guard to provide easy access from either side of the lower receiver.

Dependencies are inferred from the claim text.
