I just got my Rifle Basix trigger [ sav-rat] for my mkii and have been working on it for the last hour and a half.After installing the new trigger it will not cock and and stay cocked when the bolt is cycled with the safety in the fire position.With the saftety in the safe position the gun will cock and stay cocked. but just move the safety slightly forward and it dry fires. I have removed and reinstalled the trigger 4 time while carefully following the instructions to it still doesn't work.Any help would be greatly appreciated.
