malfunctioned to dead last in a carbine match

[Harlan (Deceased)]

I think that magazines are the weak link in the weapon, just my opinion.

I agree Dave, and also the other things you said. The stamped mags were just meant to be a consumable part and thrown away and nobody would have fathomed they'd be used 65 years later. Even beyond the springs, the lip, boby etc can dent or deform. Who knows how many times a particular mag has been rammed home over the years. When I had my carbines I used to pick up a couple of new nags at about every show I went to.

My thought about the Korean mags are if they're even slightly out of spec from a USGI, and then the IJ is a slightly a different spec too, the effect could be exasperated, and all three Korean mags could malfunction the same.

Thanks for the lead. I'll talk to him about some magazines.

Happy to help, feets. I hope it works but regardless I'd want to try the simple things first before going inside your carbine again and possibly creating another problem.

It's good to have USGI mags anyway. Send John a PM, and I'll also email him and tell him you're doing so.

Good luck!
