Flint River Armory Introdues Their New Gen2 CSA45 Gas-Piston .45 ACP Carbine

Jeremy S. - comments No comments

The CSA45 isn’t new to Flint River Armory, but their Gen2 version brings a couple of very welcome changes. Gone are the proprietary magazine and the unique receiver extension with matching stock. Replacing them are, as you’d hope, GLOCK mags and AR buffer tube compatibility. Plus KeyMod has been rightly ditched in favor of M-LOK.

While dumping the proprietary components makes the CSA45 less unique, in this case that’s a good thing. Plus, the gun is still unique in the market with its rotating, locking bolt and gas-piston operating system. It’s similar to how the SIG MPX operates, but the CSA45 is chambered in the venerable .45 ACP.

Rumor has it that Flint River Armory will be releasing more calibers soon, too. Including 10mm Auto, which is sure to be popular.

In the following video, Flint River’s Founder and CEO walked us through the features of the Gen2 CSA45 at the NASGW show:

  1. Overland Park is like Beverly Hills. A bunch of Uber wealthy fat cats. I wouldn’t pay 3K for a Chinese made scope knowing it feeds that beast.
    Buy American.

  2. Picked up a Creed and an RP9 today….have a Chiappa 60DS on order…a few more on the list.
    Prices are good…$100 rebate on the RP9.
    Lots of ammo out there at good prices.
    Mags are cheap…mostly. Except for the German guns, usually.
    Wish suppressors were not NFA…oh the hassles…and the waiting…even for LEOs.
    Oh…and now the minorities and libs are arming to defend against the alt-right…LMAO
    The gun companies are loving it.

  4. Arming yourself to protect life and limb in an uncertain world is our right as Americans. After a self-defense incident, lawyers could take months to scrutinize decisions you had to make in milliseconds. Even if you are involved in a lawful shooting, the legal system in this state can work against you. You can and probably will be dragged through the court system at great cost to you, just to prove you were right. One way to protect yourself if you need to use a gun is Carry Guard self – defense insurance. This protection is offered by the NRA. It might be worth a second look, before it’s too late.

  5. Absolutely disgusting. Every time there’s a tragedy, these bastards come out with their pre-written bills (that they planned for such an event) and try to take away Americans’ rights to defend ourselves with the weapons we choose.

    That, along with the fact that Stephen Willieford, the guy who intervened in the Texas shooting, used an AR-15 to confront the attacker! It throws everything these idiots believe out the window. But ultimately, they have an agenda and won’t stop until they force it on us.

    California should just go ahead and secede from the union, along with down-state New York. The rest of the country will be a whole lot better off without those hellholes muddying the waters.

  6. If I have to hike a dozen miles or more with a thousand rounds or more, I will take an AR-15 in 5.56mm above an AR-10; otherwise, I would take an AR-10 over an AR-15 easily. Even in my younger, physically fit days of having to lug around an M-60, weight on a long hike was important.

    With that being said, and the fact that I can now use a cart to move my ammo from the car to the range, I am okay with carrying a thousand rounds of 7.62mm and an AR-10. I can even carry the brass off the range too. 🙂
