Work greatBought 2 for my M10 submachine gun. They run great with the regular upper and with the Lage upper. I have a lage 2 step magazine release so I didn't have to modify these. If you have the standard M10 magazine release then you will have to file down the back like surplus grease gun mags.
Just like surplus grease gun mags, but unlike old surplus they are new and run great.
None.

Solid USGI ReproPicked up a couple of these United Defense mags to go with my M3A1. The stamping is clean and the dimensions are faithful to the original they drop right in and seat without wrestling the catch. I will say the follower spring is noticeably stiffer than my original OTB Firearms surplus mag, had to really lean into it to get the last few rounds loaded by hand. Overall a worthy spare for any Greaser owner who doesn't want to beat up their original mags at the range.
Feeds 230gr ball reliably after break-in
Follower spring is stiff out of the box

Great repro mags!Picked up a couple of these for my rM3A1 and they run like a dream. They come packed in heavy grease just like the old GI ones so make sure you take them apart and clean em good before you hit the range. I ran about 200 rounds of Federal 230 grain ball through one and not a single hiccup. The parkerized finish looks spot on next to my original mags too.
Perfect fit in my M3A1 with no wobble
