notrabmas Posted March 30, 2013 Share Posted March 30, 2013 (edited) Hi everyone, I'm going through some problems with my M4 I have no clue what to do. I recently bought one (3 days ago) and installed the Sidearmor Mod 3 rail system, used locktite on the threads of the screws and everything. However, now I have no clue how to take the barrel off. I know you are supposed to turn the knob and it loosens the front. My second problem is I fired it for the first time today (fired about 7 birdshot loads which all failed to eject [kinda expected them too]) and then I put 1 slug in the chamber and fired it. After I did, I went to put another slug in the chamber, but the bolt is retracted all the way in the receiver and stuck. I pushed the bolt release, but it didn't do anything. I took out the trigger assembly (which was difficult because of the bolt) and it wouldn't budge at all. I know I should completely field strip the gun, but I can't take off the barrel. What do I do? Also, does putting on the sidearmor system void the warranty? Edited March 30, 2013 by notrabmas Quote Link to comment Share on other sites More sharing options...
