Reviews
Thermold AR-15 30 to 45-rd. Flex Mag is rated 4.1724 out of 5 by 29.
Rated 1 out of 5 by from good price for a 30 rd it may say 30 to 45 rd but I couldn't even get 31 into it and then get the mag into my AR it needs some instructions

Rated 5 out of 5 by from Awesome, extended capacity magazines for the price of most 30 rounders. These mags are outstanding. Easily loaded, 30 round mags will expand to hold a fearsome 45 rounds. They are also cool in that you can put 30rounds in it while extended and not have to worry about shortening the spring life in your new mags. They also fit in the outstanding 15 magazine ammo box sold elsewhere in the catalog. The best magazine deal that I have seen for the serious AR15 owner. Uses .223 or .556 ammunition for even more versatility. Buy some...now!

Rated 4 out of 5 by from GOOD addition to below review I forgot to mention the spring is very rusted and I will see if it can be removed, cleaned up and oiled before buying another.

Rated 4 out of 5 by from Good I just noticed it is 45 rounds and I thought it was 40.I filled it and ran the bolt to see if it would go to last one and it did.I will need to put 45 in and try again but am sure it will work.I think I will order a few more if available.A little hard to get the release to compress to extend to 45 .there should me instruction with it showing what to do to extend ,but I did figure it out.

Rated 1 out of 5 by from Piece of junk. Can't be loaded easily and rust is coming out the mag from off the spring. Not a standard spring either so I can't replace it.

Rated 5 out of 5 by from Well made product. I returned a different >30rd mag for this model as the shells would not stay inside that other brand - just kept popping out. This model holds them firmly, fits the rifle tightly and have not had a misfire yet.

Rated 3 out of 5 by from Returned 1 of 3 as not functional - had to alter the others to make usable. They would not fit into the mag-well. There is extra plastic on the feed lips which must be removed carefully to function. Extending the magazine to accept 45 rounds is difficult. If you intend to use it extended you will need to be sure you have it fully loaded or insert it very carefully or it will collapse down to the 30 round size when it is inserted into the gun. Quality Standards lower than other Thermold Magazines
