Got my 9mm upper, block and hammer in the mail today. I know you've all said good things about Donnie at Sable Co. but I'll say my piece anyways. Top notch service from Donnie.

I'll take my AR to the range tomorrow or Sunday to break it in. Right now I'm using the South African dual cut Uzi mags from CDNN. It's a little hard to get them to lock into place. Should I file the cut a bit, or just work the gun a little and see if they fit better?

i'd see how they run first and then whack on them if they need it.....CDNN are pretty good folks but i don't know how they'd be if you try to return something that you've whacked on.....Dick

I got the magazines fixed with a Dremel. Just ground off a little from the top of the catch. I tried whacking on them, but some were almost impossible to get in. I even bent one of the feed lips trying to force it in. It's all good now, got to fire it (only 100 rounds). I still have 300 rounds of 9mm ready to go down the barrel of my new AR.
