PWC 9 - Sten Magazine Update

So Ive been having feeding issues with sten mags printed in PLA. Ive tried various PLA+ types and PLA+ manufacturers. All magazines could not hold more than 5 rds as too many rounds would loosen feedd lips. Thus not allowing rounds to stay in place for the bolt to pick up a round. Also, the magazine would not last longer than say 50rds.. bolt cycling would wear down the feed lips again, causing rounds to fall out of place and out of the magazine. So I went against the grain, picked up a Sunlu E2 dryer, dried some stored PC(75 @ 12hrs), then printed a 15rd double catch sten magazine in PC. Without any metal additions, the PC printed sten magazine can hold max rounds and can last a whole day at the range. I have the 8 inch 9mm version and its dialed in at 25yrds.. thing is just punching holes in my 3inch splatter stickers. Im not one to just chuck rounds down range.. too type a for that.. I need tight and accurate groupings. Anyway.. With the PC magazine this build is freaking humming. Thinking of picking up a 16inch upper for another PWC build. I also plan on a mac-11 build where Ill probably mill one out from an 80.

Now if i can only get this grip heat insert to stay in place for my 10/22 build..
