Great mags!

Impulse buy.


I actually bought these magazines without having a rifle in .308 to use them with yet... The price was right.I like that they reportedly feed well with M118LR as well. Now, to start a .308 build.

I am very pleased wit the magpie 7.62 mag, but its only been on two range trips. So far it has run without an issue. I would recommend and purchase again.

Fast and Correct
