The FM15-223-G2-16I-2FTT is a semi-automatic AR-15 rifle chambered in .223 Wylde so it accepts, chambers, and fires both .223 Remington and 5.56 Nato flawlessly. The rifle is unique in the marketplace due to its many high-end features that simply cannot be found elsewhere at anywhere close to this price point. This stunning rifle features a patented 4-position non-reciprocating front charging handle, a one-piece aluminum charging trolley, a nestled recoil spring assembly, a low-mass bolt carrier, and a intermediate (between mid-length and rifle length) length gas system with an interlocking gas key that helps reduce the points-of-failure that are often found in traditional AR-platform rifles. The rifle also incorporates a proprietary patent-pending integrated recoil system. This rifle is built with a Gen 2 billet aluminum monolithic-style upper receiver and premium billet lower receiver serving as its foundation. It also utilizes a match grade 41V50 16" steel barrel with 1:8 twist that is surrounded by a beautiful15" M-LOK handguard.
