I once heard it said that Dremel is an Italian word meaning "watch me screw this up". When using a Dremel, proceed with caution.I had a friend with a Dremel widen the slot as much as he dared and still had no relief with my Magpul mags. I have found one polymer brand that DOES work but wouldn't you know it, I've forgotten the brand name and as I write this, I and and my SU find ourselves in different cities. Will have to get back to you on that. The pic below is the 20 rounder in place. It loads through and ejects just fine from both stock locks.
I have a Lancer 20rd; it locks and functions fine, but my unmodified Charlie stock still does not close around it.The magazine shown is a Lancer AWM 20-rounder in FDE. Gives me something to work with as soon (if I thought I needed it) right out of the bag as it fits in the bag as is.
Thanks! I have not tried to whittle on my stock. I have a number of metal mags; that was one reason I bought the SU in the first place. I have picked up some polymer magazines and if I use them, I'll just forego folding the rifle, and/or save them for my AR.I do not think widening the gap in the C stock is a good idea.
Worse case is a new stock probably only cost 80 bucks.
Maybe just buy a few metal mags.
If you are desperate. Mail me your P mags and I will swap them out for lightly used metal mags.
