I need help bad with my rifle guys! I bought a new Choate Tactical stock for my 10fcp-k and it's stuck! When I first put the stock on the rear tang for the safety and the stock had a gap when I tightened the front action screw so I was thinking remove material off the rear action bolt or shim the front bolt. I did a test fit before I did anything and dry fired to test it and the trigger would'nt budge, so I recocked it and it fired. Now the big problem is the rear action screw will not back out to save my life. Does anyone have an idea what is wrong? Please help! Thank you! ???
