20 round capacity that fits the Nylon 77 series Mohawk 10C and others.
Finish is black oxide over carbon steel, with a stainless follower.
These magazines are fully laser cut, and are welded instead of crimped together.
View holes at 3,5,10,15, and 20.
Magazine feed will be slightly sticky the first couple uses.
We recommend inserting the magazine on an open bolt.
Ammo selection:
Please note that many longer bullet profiles result in sluggish feeding as the added length causes binding in the magazine.
Since the Nylon 77 cycles extremely fast, the ammo needs to be about a perfect match to feed reliably especially in the 15 and 20 round magazines.
The normal issue is empty chamber failure to pick up a cartridge.
We found that Remington Yellow Jacket bulk packs seem to work about the best. They are fairly cheap and fairly common.

I haven't fired yet to see how they feed, but I sprayed down the inside with Blaster dry lube and worked the follower up and down for about ten seconds with a chop stick and now I can load a full 20 with my old fingers without the little included tool.
I've been waiting for these mags since the '80s lol.
