I finally got my new POF 308, however, I think I have an issue with the gun. The gas plug moves freely with no feeling of detent and can move from setting to setting with little to no pressure. I wanted to remove the gas plug, however, no dice. I tried depressing the button on the plug and rotating to every posssible position and I had no luck. I have a call out to POF, however, does anyone who has a POF 308 know whether I got a defective gun. It certainly appears that way to me. How does your gas plug feel?
