"These are either mismarked or grossly oversized. I received these Thursday evening and as I wanted to shoot a benchrest match this weekend, I was glas to see them, however when I attempted to put the mag in my DPMS AR style carbine, I found they wouldn't go in. I started one into the magwell and about 1/2 inch later it was so tight I had to pull with two hands to remove it. I took the second one out of its' individual package and it was exactly the same, wouldn't even begin to go in the gun. I recently bought a 30 round polymer mag from CTD and it is the best mag I own, even better than the DPMS mags. It is different brand from the 10 rounders but at least I know my gun isn't the problem. Will send them back and hopefully CTD will figure out what the problem is. As I am writing this I see they are listed as out of stock so either there is a problem with them and they stopped selling them or I bought the last two in stock, which I doubt. If they resolve it I will write a second review describing the problem I have been extremely happy with CTD service so I'm sure I can get a good outcome from this."

"They did not lock in the indent of the mags as they were about 1/32 off. A few seconds of work with the dremel and they work fine."

"CTD came through once again, I love this company. As for the magazines I just ordered (2 of them) they did not fit as the one man says.... but the only problem was the corners are too sharp, so a few minutes with a dremel file or palm sander to round the corners and they fit in my DPMS. But they feed a lot better with 8 rounds in them rather than 10, which I dont mind at all."

"everyone has been out of 10 round mags for the ar15, so I decided to try these. They do not work in my 4 differnt ars, they do not lock into place- stay away! And just wait for other companys to come off back order"

"Received them right away (great shipping, CTD), but when I tried to use them, they were a bit tight (empty). Once I tried them fully loaded, I was disappointed because they jam my AR. If I buy a magazine, it should work right from the package. If I want to bother fixing things, then I'll build it myself. So, stay away from this crap and don't waste your money. Yeah, they're cheap, but just spend the extra few dollars and get a better one."

"Fits great, feeds well, ejects with no problem, what more can you ask for? Well, expect that my stupid state of Cali only allows 10 rounds mags and should allow larger. I purchased two and they actually fit and work better then the stock one thaat came with my bushmaster Carbon 15. I want to buy more but Alas they are out of stock."

"Read other reviews and had my doubts, but bought anyway. Mine fits perfect, so changes were made at the factory. Loads perfect with my speed loader. In MO you can't legally be in the woods hunting with a mag that holds more than 10 rounds in your weapon. This solves my problem! very pleased with the price also. At every gunshow or shop I've been to, they are priced twice as much as 30 round mags. Probably will add 1 or 2 more on my next order."

"When they work they're great, when they don't they stink. Bought several and pre-tested in my Colt Sport lower, all worked great. Three of them are too tight for Palmetto lowers. I will use them in rifle that works, and for the price won't piss about the ones that don't. Spikes Tactical aren't crazy about ASC mags. Not all mags fit all rifles. Buy what works, return what doesn't."

"Bought 5 of these for my son and myself. Fit is too tight for my DPMS lower. Fits my son'd ATI polymer lower fine. Pretty cheap construction, but they work if they fit. You get what you pay for."
