Hey crew. I'm the new owner of an M4 (11707) and I've only fired about 50 slug/buck shot cartridges through it. After a basic cleaning after the range, it's now only accepting a quantity of 4 - 3" slug cartridges in the magazine. Depending on the manufacturer, I can fit a total of five 2-3/4" cartridges, but some are just a little too long and I can only fit 4. Not quite 5. I didn't have this problem until after the range. It originally held 5 as designed, but now it's as if there's something jammed in the magazine, preventing a full load. I never removed the spring beforehand. Just a basic cleaning. I have since removed the cap, spring, and follower to check for blockage, but found nothing. After reinstalling the spring, I'm having the same issue. The only thing I can think is that the spring is damaged (no sign of obvious damage upon inspection), or compresses oddly while loading, and prevents a full 5 load. Anyone else have this issue? I'll take any input you all have. Thanks.
