M1 Carbine 30-Round Magazine
The United Defense M1 Carbine 30-Round Magazine is a high-capacity feeding solution patterned after the original USGI "banana" magazine used in the M1 and M2 Carbines. Built from heat-treated high-carbon steel with a protective black oxide finish, it holds 30 rounds of .30 Carbine and drops into any USGI-spec carbine without modification. The curved body, proper spring tension, and clean feed lips deliver the reliable cycling you expect from a mil-pattern magazine. A solid choice for range shooters, collectors, and anyone running an M1 Carbine who wants extended capacity at a working-man's price.

Works as good as my originalsCycles just as smooth as my original USGI mags but for a fraction of the cost. Finish is a little glossier than the old military ones but thats not a big deal at all.

Fun as heck at the rangeBought a couple of these for my Universal carbine and they have been a blast, no pun intended. Came in good shape, black oxide was clean no rust or dings. Fed my Korean surplus ammo with zero hiccups through about 200 rounds. The 30 rounders just make a day at the range more fun, way less reloading. Only thing is the last 4 or 5 rounds take a firm push to seat but thats normal for these.
30 rounds is just plain fun
Last few rounds load stiff (they break in over time )

Good banana mag for the moneyGot this as a spare for my Universal carbine. It locked in fine and fed 30 rounds of Armscor without a hitch. The finish is a bit glossy compared to my old GI mags, but that's cosmetic.
Fair price

USGI-spec magsBeen collecting Carbines for about 15 years now and I've cycled through every mag option out there. Original USGI mags are 70+ years old at this point and you're rolling the dice on feed lips that may or may not have been abused over the decades. The KCI Korean mags are decent and I run a few of those, but these KeepShooting MIL-SPEC mags are something else entirely. You can tell they're built to the original specs - the follower engages the bolt hold-open like it should, and the weld seams are clean. Loaded up 30 rounds of Aguila and ran two mags through my IBM last weekend without a hitch. The parkerized finish matches my vintage mags almost perfectly. Yeah they're a few bucks more than the KCI stuff but you're getting genuine USGI-spec construction here. Already ordered three more.

Excellent Quality for the PriceI was looking for a reliable 30-round magazine for my USGI-spec M1 Carbine and this one exceeded my expectations. The all steel construction with the blued finish looks great and matches the classic military look of the rifle and it feeds every round of .30 Carbine smoothly in both slow and rapid fire.
