    Flint River Armory is a firearms manufacturer located in Huntsville, Alabama. They’ve released their first product – CSA45 (Carbine Semi-Automatic) carbine. It is designed from ground up to be a dedicated pistol caliber carbine chambered in .45ACP. It is a gas operated gun with a short stroke gas piston.

    CSA45 features machined receivers from billet 6061 T6 aluminum. It comes either as a rifle with 16″ barrel or as an SBR with 10″ one, and both barrels have threaded muzzles. The forearm of the gun is available with KeyMod or M-Lok accessory attachment options. The lower receiver is monolithic with the buffer compartment, which is meant to make it a stronger design. The gun also has a telescoping buttstock made of glass filled Nylon. CSA45’s upper receiver houses a reciprocating side charging handle on its left side.

    Another interesting feature of this carbine is that it uses standard AR-15 lower receiver parts. So the controls should be familiar to most of the customers. It will also allow the users to upgrade the carbine with one of countless aftermarket AR-15 triggers, as well as easily and cheaply replace broken trigger control group parts. CSA45 uses a proprietary stainless steel 25 round magazines. The gun also features a four lug rotating bolt.
