Did I miss a memo somewhere?
I dunno if the mags are shitty or what, I'm trying to load 762 fgmm into 3 mags i have. And having issues. I know 2 maga are junk.  They wont even feed and a cycle through the gun. I got them from cabelas and even brand new they qouldnt even load. I filled them with clp to loosen up the springs a bit to make them somewhat useable.i own a bunch of pmags and never had that happen before.

PMAGS have trouble with long loaded ammo.  They came out with a specific mag just for that.

I use LaRue mags for this very reason.

That said - I have shot a lot of FGMM out of standard PMAGS and never had an issue.

There is a longer COAL version

Yes sir. I was hoping  to hopefully save a bit of noney with the pmags. My larue mags fed them flawlessly.

If you want to save money on AR10 mags - try some of these:  http://palmettostatearmory.com/d-h-20-round-aluminum-ar-10-magazine-with-psa-baseplate-black.html

Eta: thanks!  Lancer mags any good? Aka would i  still have the same issue? Thank you.
