For curiosity sake, I kept adding mags to the cart until it said they did not have the quantity available. Looks like they have 22 in stock. Definitely rare!
The mags are not that hard to find. I've got a couple still in the paper. But that is a pretty good price these days. I've got 2 Ingram Model 6's (1 military and 1 police) and about a dozen mags. I bought a couple of mags before I got my first M6. These guns are a real pleasure to shoot! And much lighter than my Thompson.
10 years ago a company had a lot of them, (I can't remember the name; SAMCO?) but, were asking $275.00 each.
I agree that is a good price for NOS M6 mags.
I bought two for $291 delivered in 2018 but don't remember who from. I haven't owned an M for a while but the time to buy something is when you see it. Anybody have any of those $400 1919A4 kits they want to sell? Or the $95 Bren kits IO had?
