Gun locked up solid in the middle of an L drum. Bolt fully to the rear and will not move. Trigger moves but not full travel . Attempts to remove the lower, same result. It is locked in place and will not move. I have used light hammer pressure on both bolt and lower with no motion noted. My only thought is to remove the lower fire control pins to get it open. Anyone out there ever been in this spot? Also, the gun is set up with 21 parts, actuator, buffer, spring and has run flawlessly for years. TIA
