Anybody have experience with the Rock River Arms 9mm carbines? I already have a couple of .223 AR-15s, but the 9mm ones look "interestingly different."
I am almost done building my own. I got all the parts except for the buffer tube assembly. I went with the cproducts mag block. I'm still waiting on the tube before I can take it out. From the fit and finish of it, it seems like its good quality. I've not heard bad things about it.
A lot cheaper to feed too, especially if you reload.
