The CETME that I had was a complete POS (it was from CAI, naturally). I don't even know where to begin trying to describe that thing. Mis-aligned front sight, jacked-up charging tube which would make cocking the rifle a b!tch, ill-fitted receiver with bolt carrier dremeled/chewed in order to fit, mag well so out of spec that the mags would not feed reliably, that's if you could get the mag to seat in the first place.
My first and only outing with it was rediculous. It would jam about every 3rd or 4th round. Accuracy with it, however, was the only decent thing that I can really say about the rifle (about 2-3 moa @ 100-meters w/ mil-spec).
Now, let me say that NO, I was not expecting something along the lines of an FAL or M1A, however, I wasn't expecting anything like what I got out of it, either. Hell, the SKS rifles that I've shot were more reliable.
Evidently, I wasn't the only one that got a bad one. My dealer ended up getting all the ones he sold returned as trades. He hasn't stocked them since.
