The FM-9 complete upper receiver assembly comes with a large assortment of features and improvements over standard pistol caliber carbines. This AR9 features a forward mounted fixed charging handle instead of the traditional M4 T-handle. This makes it much easier to charge your SBR or pistol without coming off target. This non-reciprocating charging handle can also be moved to the right side for left handed shooters. The monolithic upper and handguard are attached via a proprietary locking system to ensure that it doesn’t loosen over time. This free float rail also uses the M-LOK system, so you can attach your favorite lights, grips, or other accessories. Underneath the M-LOK handguard is an 8.5” 4150 chrome moly barrel that has a 1:10 twist to stabilize all 9mm bullets. This complete AR-9 upper receiver group is a great option if you want to quickly assemble a 9mm pistol caliber carbine for home defense or the range.
