The wire folding stock appears to be original; so I'll remove that and hang on to it. The barrel extension is pressed in place. I've been able to spin it but not press it off yet. I'm hoping the barrel is unmolested, so I can thread the end to accept a standard brake. The gas piston/bolt carrier machining is rough, and original.(sigh) This is my first Romanian. Is there any reason not to turn this into a shooter/training/class firearm?
