Been a while, so I was dusting my guns of to make sure they worked. I tried to shoot my M4, but no bbs would discharge. I could feel air coming out of the barrel, and took off the front-end to feel air coming out of the nozzle. BBs were loading (tried different mags) and barrel was clear. After about an hour I looked down the hop-up cylinder loading from the mag well and noticed the air nozzle is covering the hole (so no bbs actually make it into the barrel. I can push on the air nozzle and it moves a little less than half an inch. The hop-up is mating up to the rest of the gun (where the air nozzle is inserted).
Any clue why the air nozzle is intruding so far into the hop-up?
I can't see anything that should be holding the air nozzle back.
