Model 1 Sales: 5.56/.223 Pistol-7 1/2 Upper
Here is the one I got from Model 1 sales. Fun toy for only $350. Comes complete. All parts stamped RR. Rock River???? Hell I dont know.
Quality, hell I dont know. Accuracy, hell I dont know.
But me and a bud took it too the range with about 3 or 4 hundred rounds of different types of ammo and it ate everything we put in it. Not one hiccup.
Perfect house clearing gun.
Plus great for starting camp fires. Damn flame will even get a pile of wet wood too blazing.
I love the little guy.

I really like the PWS diablo in 7.62x39 but it is pricey.
