THE NEW CSA45
Starting MSRP $1,59500
Designed From Scratch
The CSA45 is the first .45 ACP carbine to feature a rotating/locking four-lug bolt and a short-stroke gas piston -designed from scratch. Unlike other pistol caliber carbines, the CSA45 isn’t an adaptation of a pistol into a carbine, nor is it an adaption of a carbine to accept a pistol caliber. The CSA45 is a carbine that was designed from scratch around the .45ACP. From the form factor, scale and balance, to the operation; every element of this carbine was designed, developed , and tested to best compliment the characteristics of the .45ACP round. —When the founders of Flint River Armory say that thisweapon system was “purpose-built,”, you can see why.
Not Another AR Conversion
At first glance, this weapon may look like an AR — but it’s not! In fact, the only AR parts used on the CSA45 are the fire-control system. The rest of the gun was meticulously designed from the ground up with the goals of strength, accuracy, reliability , and simplicity in mind. Machined from 6061 T-6 aluminum, the body of this weapon is built for strength. The monolithic lower encompasses the buffer compartment; diagonal placement of the takedown and pivot pins provides structural rigidity. If you ever needed the confidence to beat down a door with the butt of your weapon, the CSA45 gives you that!
Performance Firepower From a .45ACP
Performance testing shows that this carbine not only looks the part but functions far beyond expectations. 1-inch groups at 50 yards is par for the course. At 100 yards, very good accuracy is maintained. With very little barrel rise it is easy to stay on target and double-tap like a pro. And with this carbine, you can shoot any standard load .45ACP rounds, including ball, frangible , and hollow-point.
