I've owned a Keltec RFB for a few years and have no complaints. It's compact with the ballistics of an 18" .308. I bought several metric FAL mags when they were still cheap and easy to find. I used it on a Texas hog hunt and appreciated it's short size when I was in a blind. Got a moving pig at 200 yds with it. The only negative thing I can say is it's heavy.
