Marstar's mags are apparently not US-made, but not China-made either. That's all they were able to tell me on the country of origin. I bought only one to test it.
On reception, I compared it to my SAinc mag. It's lips were bent wrong and rounds wouldn't slide out properly. I had to re-bend them and it was easy, which means the metal isn't treated as it should. Second issue, with 1 to 4 rounds, the mag worked correctly but with the 5th round in, it wouldn't lock in my rifle because it was pinned at 5 instead of 5.5. I had to open the mag and cut a dent in the follower so it would sit to 5.5.
Quite a crappy product for the price. I'll never buy again from them.
M14 mags are so overpriced even for the cheap stuff IMO, you may as well pay a little more and get the good stuff.
Dlask Arms has US made Checkmate Industries magazines for not much more than cheap mags. M14 mags are so overpriced even for the cheap stuff IMO, you may as well pay a little more and get the good stuff.
spend the extra couple bucks and get CMI mags from CTCsupplies.... well worth it.
Good friend of mine in the US seeks out Polytech mags that were imported before
their ban on Chinese firearms because in his experience, they're excellent.
Wrong!A lot of stuff SA Inc passes off as American made is not. Brazil, I think. No heat treated parts in a magazine either. Mostly stamped.
I do the same thing. Poly Tech mags that were imported into the USA are excellent.
They fit and function in my Poly Tech receivers just as well as C.M.I. and USGI mags.
