These magazines came well oiled, and in good condition. The followers did not stop the action as expected but overall are solid mags.

VERY GOOD PRODUCT

Do yourself a favor and do not buy M1 carbine mags from anyone else. These M-1 magazines load perfectly. You won't be sorry I know I wasn't.

Thought it did a little better than my 15 round mags. But my carbine is to blame for feeding issues.

After reading horrible reviews on other 10 rd mags for the M1 I decided to give these a try. Overall for the money they aren't bad, the base plate on one of the three i purchased started to slide off but was easily pushed back into place and seems fairly secure now. There were a few failures to feed properly out of the 200 or so rounds I put through them at the range. All in all not bad for the money .

Great service great quality products, 10 round m1 carbine mag's

The most recent restock (8/18) are the best yet. The batch I got in 2017 - before they went out of stock - required a significant amount of time to clean up the burred underside of the feed lips as well as the forward edge of the follower. This batch (8/18) needed very little deburring - although not zero - and the follower didn't need to be touched at all. All the springs were properly installed and required no adjustments. These are as close to my 15 round USGI magazines as I have found - much better - another world better - than the 10 round Pro-Mags I ordered when these were out of stock - and that were sent back to the internet seller 10 minutes after they arrived. While I have not been to the range yet with this batch the 2017 vintage worked very well and I expect these to as well.

I will start this by saying for those of us living in Komifornia this is the best 10rnd mag i have come across, that being said though it still need some tweaks after you buy it. Out of the first two the I got one of the springs was put in wrong. That is easily fixed as one of the other reviews already talked about this problem. The other problem it has is that at the front of the magazine the metal is rolled in such a way that it will snag the edge of your shell and sometimes cause a jam. this two is easily fixed. I purchased a grinding stone meant for a dremil and put it in my 19v drill and just slowly ground the lip back until I could easily move a shell in out of the magazine with out it catching. I also rounded off a point on that back of the mag that I had kept pinching my thumb on when loading the magazines. the grinding stone only cost my $3 at home depo so its not like the fix cost that much. now i can trash the other 10 rnd mags that i had gotten. they are worthless. they jam for no reason and will eject them selves while shooting. I hope Keepshooting reads this and makes some changes to there fabrication process to solve these two problems. if they do they will have the only 10rnd mags worth buying on the market.

initial use of 3 of the 10 rd m1 carbine magazines resulted in all 3 causing a malfunction. this was caused by the follower tilting up at the bullet end and the round coming out nose up. disassembly revealed all 3 had springs installed backwards. springs reinstalled with proper orientation and now magazines function. hard for me to rate this mag.works good now but initially no go...

I recently aquired a Vintage M1 Carbine. It came with 1 10 rd Promag Magazine. I ordered a Keepshooting 10 rd Mag mostly because I've had problems with Promags before with other firearms. After a good cleaning and lub I took it to the range. The Keepshooting Mag locks in tight and feeds the M1 flawlessly. No problem. The promag doesn't lock in as easy. I have to pop it a little to seat it in. Also the Promag doesn't hold rounds in place. They tend to move forward when loading. I have to keep pushing them back. I've already ordered another Keepshooting Mag. I'll still be looking for a USGI mag jusst because I want one but very satisfied with Keepshooting Mags.
