These are the best I've found so far not only do they feed better but they knock the weight down. I'll probably buy more.

No issues
I bought 3 in 2019 and have never had any issues with them so I recently bought 2 more. They actually do go in a little easier than the factory mag I have. They’re nothing fancy but I don’t have anything to complain about. They work and that’s all I ask of them

Only holds odd numbers of rounds
You can only hold 19, 17, 15, etc. rounds in this. If you load it with 20, 18, or 16, the top round will pop out. The left lip that holds the left round in place needs to be longer.

Solid choice
No real complaint for the price. The molding at the front of the magazine has two recesses designed for the tip of the bullet to pass through, and I had to do a bit of clearance work to get 168 grain ammunition to feed properly. These fit just fine in a Springfield M1A, but when I upgraded to a James River some work to the lug to get it to lock into the magazine well without having to beat on it.

This product could be a lot better
I have two issues with these magazines. 1. The follower doesn't engage the bolt hold open catch. 2. I had to file down a portion of the lug on the spine of the magazine to positively engage the rifle's magazine catch.

I purchased 4 for my new M1A. 2 magazines worked flawless, but 2 have issues of not cycling till it was down to 14 rds, maybe they just have to break in. I will report back after a trip or 2 more to the range.

Could not get these to in
Could not get these to insert into my M1 precision. I wasn't going to file down the cheap plastic in order to get it to insert into my rifle. They are not anywhere near the quality of magpul magazines, or the factory or CMI mags. Lets hope that Magpul will make mags for the M1

Bought three of these. Two will only hold 19 rounds and the slightest shake will knock rounds loose. They all feed badly, about 1 misfeed every 5 rounds on average. They are also falling apart after about three runs through my M1A. I have never had a single misfeed or problem with either of my Springfield magazines so I was very disappointed by these. I tried multiple brands of ammo, firing more slowly, scrubbing down the rifle and magazines, nothing I did made any difference.

I bought three of these for my M1A. I have shot approximately 60 rounds through each magazine with no problems of any type. I like the weight and the easy to disassemble for cleaning (when that time comes). I have several steel magazines from another CTD vendor and they also work perfectly. They just are heavier and cost more to buy. I would buy them again.

I got three of these from CTD. I have 20 and 25 round steel magazines that work well. These zytel mags fit into the rifle easier and feed nicely. No problems after 40 rounds through each. More later if this changes.

I bought two of these mag
I bought two of these magazines and they have so far performed flawlessly. They seat quicker and easier than the steel magazines. The spring and follower are smooth and I had zero feeding issues even when I loaded the magazine to max capacity. They are light weight, compared to a full steel mag, and durable. Works great in the Arizona desert. I plan to buy more to phase out my steel mags. Two mags will fit in the standard green GI Ammo pouch.

I bought four of these magazines mostly because of the price. I loaded the 4 to capacity and all functioned well. None of them jammed, all locked back the bolt and all shells fired without problem.

You get what you pay for
You get what you pay for with this product. It isnt the right length or something and the bullet wont catch with the slide so it jams constantly. Dropped one magazine and it practically fell apart. Thinking about getting a pro mag.

No issues as of yet. I put only a couple hundred rounds through it so far. I noticed a small amount of flex near the opening of the magazine but when inserted into the rifle it loads and locks easier than the Springfield steel mag. I have a composite stock and these composite mags look as good as they function with my stock. Plan to buy more.

The bottom plate on these
The bottom plate on these have a manufacturer flaw in that the locking tab is not made long enough causing bottom plate to not lock in correctly or fully. As mentioned by others for this item . I purchased two of these; one had the bottom plate issue and would not hold ammo or completely lock into place at all. The other is holding in place, but length still not as it should be to hold securely long term. Looks like it will not last long. Time will tell, so 50/50 toss up to get a good one.

DO NOT BUY THIS. I LOAD THE CLIP AND INSERTED IN TO MY M1A. I SHOT 1 ROUND AND THE BOTTOM FELL OUT. IT HAPPENED TO 3 OUT OF 4 CLIPS I BOUGHT. THIS IS JUNK.

This is an excellent prod
This is an excellent product. I read about a few issues with the magazine so I purchased one and put 200 rounds down range with it and no problems. I plan on buying more and will update as I continue to use them.

After putting rounds through it, I like this magazine and will buy another. Good points:-locks in very smoothly (moreso than SA mags)-locks in tightly/ no wiggle-no failures to feed so farbad point:-bolt does not lock to rear after last round when I use this magazine. For the price, it performs a lot better than those 25-round mags this site also sells.

Don't buy these, I put three rounds through my Socom and the bottom fell out, so I put it back together and reloaded it two more rounds and the same thing. Buy the CMI, or the Springfield mags!

Great mags at less than half the price of the Springfield 20 round mag. Looks great with the synthetic stock of a SA M1A. No problems feeding, ejecting or holding the bolt open after last round was fired. I will buy more from CTD soon!

Bought 4 to try in a M1A
Bought 4 to try in a M1A Scout with wood stock. Mags lock into place very easily without modification, and I've had no problem with the bold action staying open after the last round. Nice and lightweight, follower moves very cleanly. Trying to break them in so only loaded half way and fired one time so will update regarding durability over time.

I bought two of these mag
I bought two of these magazines just to see how they work. I've had problems with the USGI mags, and have been dying for a polymer mag. These are SUPER easy to load, lock into the mag well tightly, and I had no feed errors (not to mention that it just looks plain cool). The only downside is that the bolt won't lock open upon ejecting the last shell, but that's no big deal in my book.

Like the other reviewer s
Like the other reviewer said, this magazine fits better than the factory 10-rounder that comes with the M1A. It's a very smooth fit and locks in just fine. I have yet to load and fire rounds with it but for now, I'm extremely pleased.

I have fixed the problem
I have fixed the problem with the two magazines that were not locking the bolt back after the last round was fired. I placed a small strip of double sided foam tape on the edge of the plate that pushes the rounds up; leave one of the sides of the tape with the smooth film because you don't want that to stick to the inside of the magazine. The foam tape has the perfect thickness to push the pug over enough to push the bolt lock into place. I love these magazines and plan to buy more in the future.

I bought four of these magazines because I like the fact they are synthetic. I have a standard M1A synthetic stock and these magazines look great and fit better than the original metal Springfield magazine. Now there are two issues I have with these magazines.1) At first the magazine was not locking into place, but after filing down the top of the rectangular peg on the back just slightly it worked great.2) Two out of the four magazines will not lock the bolt back after the last round. The small peg inside the magazine seems to be leaning a little too much to the right missing the bolt stopper. Other than those issues the magazines loads each round just fine; I was firing Federal Ammunition 180 gr. and 150 gr. soft points.
