This is a very common complaint, sticky chambers. Just get the chambers reamed by a smith. (Or, for a while here a kind forum member was lending his reamer to other members. That might still be available — I don’t know.)…always experienced sticky ejection...seemed to get dirty quickly...maybe the cheap ammo
I think the M18 is one of the most fun guns to shoot that I have. I added a yellow insert to the front sight so that I could see it better.
