I have an Imbel kit and with the piston installed, I put in the gas plug and if set on A there nothing to hold it from turning. I can simply twist it right around and it comes out.....if set on G the spring loaded pin will hold it in position. Shouldnt the pin that goes through hold it in some how in the A position? The notches in the gas block are kind of worn, so do I have a problem?
thanks for helping a noob
Check the ring at the end of the spring loaded pin on the plug too. It could be worn or missing. The pin is peened to retain the ring/washer. Maybe simply replacing that part will fix it. DSArms has a replacement fairly cheap.
If that doesn't do it maybe the gas block is bad.
