MDT polymer AI type mags

[JMBD2112]

Searched and didn't see any threads here. Have any of you guys had any experience with polymer AI style mags? I told my wife I wanted some 10 rounders for Christmas and while trying to find her a link to order from I stumbled upon these....

The AI 5 rounders I have work perfect and I wanted a couple more, but @ $50-60 a piece I went with some accurate mags and have had feeding issues with them. These are 1/2 the price of the AI 10 rounders but I don't want to run into the same issues that I have with the accurate mags. They're for an AICS. Thanks for your input.

I wouldn't use them, as I need to load my .260 longer than the stated max OAL of 2.800".

Mine are at 2.785 (.308), so I might have a tight fit

I'm in the same boat on that score as well, otherwise I'd pick one up and give it a shot.

My .260 load is out to 2.885" or so.
