National Magazine 30 Round Black Mag For HK91/308 Winchester - 308 Winchester/7.62 NATO Caliber, 30 Rounds, Aftermarket Origin, HK91 Model

Got 2 of these for my HK91. They appear to be M-14 mags with an adapter spot-welded on in order to fit into an HK91. The adapter is 3-sided and the open edges have been very poorly ground down to make them smooth...... it didn't work, I still had to file the edges. The reason I think they are M-14 mags is the one of them still had the tab welded to the back side of the mag that locks into the M-14. One mag had the tab, the other one didn't, they didn't even match. Have only used one mag and in 30 rdns there were 2 rnds that failed to eject all the way, not a good average. None of my steel and aluminum 20 rnd mags have ever failed to eject. Even though they were cheap, I wouldn't bother to buy them again.

Just got 5 of these and am very very pleased. All of them fit tight in my PTR and functioned perfectly. I have one of the old style 30 round mags with the weld in it. The weld has broken a couple of times and had to be repaired. These new National mags are 5 STAR and no worries about a weld breaking.. LOVE THEM!!!!! One thing, a couple of websites say the follower is plastic.. That is wrong the internal follower is definitely metal....
