unixdawg Posted December 5, 2019 Share Posted December 5, 2019 I am having problems with my M4. It always seems to be the 3rd round doesn't fully load. It gets caught in the process. Would this be a problem with the spring or should i look at something else? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted December 6, 2019 Share Posted December 6, 2019 More details please. You mean you cannot insert 3 shells into the magazine tube? Or from a full magazine tube, the third shell fails to feed into the firearm? What kind of ammunition are you using? Any aftermarket items added to this M4?

unixdawg Posted December 6, 2019 Author Share Posted December 6, 2019 (edited) Sorry i also typod this. This is an M2 not an M4. The plug is installed and no other modifications. The 3rd shell always gets hung up. If i pull back the bolt and release it will chamber the round. I have completely disassembled and lubricated everything. It's always the 3rd round. Thanks!

Steve Rose Posted December 6, 2019 Share Posted December 6, 2019 If this was a gun with an extended magazine tube I would tell you the magazine spring it too short/too weak – the last round coming out of the tube does not get pushed all the way back into the action....but since its a factory length tube something else may be the problem....but I would try a new magazine tube spring first, and make sure the plug is installed properly and not binding up the spring. When reassembling the magazine parts: Follower > spring > plug (with big end toward the muzzle) > spring cap Quote Link to comment Share on other sites More sharing options...
DailyEDC Posted December 7, 2019 Share Posted December 7, 2019 Is the FPS higher than 1300 on your shells? I had a similar problem, my shells had FPS under 1200 so there wasnt enough recoil to fully cycle the rounds. Once i started using above like 1280 i think, it hasnt jammed since. but previously jammed every other shell. i think you can use lighter shells once the gun is broken in.
