GhostMutt you got a good one!!! I have about 5 to 600 rounds through my 1- 1/2 month old 15/22 sport!!! I bought three new mags for it they worked ok but not perfect but the mag that came with it would not function properly at all stove pipes and FTE's took all the great info on this site and could see ejector was not right so fixed that and just went ahead and got the Volquartzen extractor and my rifle is flawless with many types of ammo!!! so I can't say if it was ejector or extractor but one thing I do know it was frustrating to not have my new 15/22 not work right out of the box!! Anyway I absolutley love this thing and can't wait to go to range everyday to shoot it!!!
