Magazines for 300 blackout in a 700

[Adam B]

I put together a Remington 700 in 300 blackout. The problem I am having is locating magazines for it. I know AI stopped making the plastic 223 magazines, which work great. I bought some of the new ruger PRS 223 magazines but those don't seem to work right. Has anyone had any luck with a specific magazine?

I don't have any experience with the blackout but MDT mags work rather well for 223 and 223 ai. I can load 2.5" oal in them.

I ran MDT .223 polymer magazines in my old custom R700 in 300 BLK. Never had a problem with them. Stay away from Accurates steel mags with plastic inserts, never could get them to work right with the front heavy 300 BLK rounds.

I run the accurate mags in my 300 blk and don’t have problems.
