"After using several beat-up 10-round mags over the years, I decided to try out this new M-1 Carbine 40-rd mag. Works great - solid steel, good finish, good workmanship. Most of all, at the club price, it's a good value."

"I bought this after shooting \"beat up\" or \"broke in\" 15 round and 30 round clips for some years now thinking \"sweet\" 10 more rounds....well hmmm... i give it 2 bullets Only because it \"looks\" cool. tome this is Strictly a \"Novelty clip and unfunctional. it dont feed worth a poop. will stick to 15's and weld 2 30's back 2 back. Heck maybe it just needs \"Broke in\" HaHa!"

"this magazine is nominal at best.my example is welded together with a serious missmatch.the rounds don't even contact the one feed lip at all, but the rifle bolt does.most carbine mags are a wrap around design with a welded seam up front, and the magwell is designed to work with that.this mag is a double clamshell design with a buttweld front and rear.this is a very weak design and adds little support for the feed lips.a full magazine swells noticably but still enters the magwell.I will have to rework the feed lips before the gun will function with this mag."

"Well, i figured 40 rds. would be sweeter than a 30 rd. Mag. but its ability to stay in the gun without modification, sux. it needs to be ajusted but if you hold pressure on the mag forwards, it fire just as quick as you can pull the thrigger, so ill give it 3 bullets."

"The mag does not work at all with my completely original M1. It will feed once, then after a shot, you have to eject the next one, and load the next round. My 30 rnd and 15 rnd mags have no problems what so ever with my gun."

"This clip was not worth even the shipping. It kept jamming up while trying to load and would freeze up during feeding of weapon. Even using the clip holder with the three notches. If you want something reliable - don't get this one. Stay with the 15 or 30 rounds. Lubicating the clip dosn't help either."

"Don\uFFFDt waste your money! I heard that the cheap imported high-cap M1 mags are junk but I just had to find out for myself. I purchased one of these and it failed before I had fired 5 rounds thru my vintage WW2 IBM. The follower stuck in the bottom of the magazine. I had to disassemble it to free it up. The metal is thin, flimsy and prone to dents. The weld on the seam is poorly done leaving lumps and bumps for the follower to catch up. The follow is a small piece of stamped steel with no anti-tilt design feature that I can identify. The only truly reliable mags I\uFFFDve found for the M1 is the original G1 and the 5 round mags for hunting."
