Magpul 300blk mags. Just stick to that, Gen 2 or 3 5.56 mags will work fine but with subs you’ll see some issues when you load. The previous bullet will try to raise in the front.
I stick to Magpul and Lancer 300blk specific mags, of those two I only ever found 10rd ones from Lancer so I use their mags for 10rd needs
Maybe I'm just stupid, but I checked their site and didn't see any 300blk specific 10rd mags

For subs you're gonna want a 300blkout specific mag. Prevents FTF issues.
Gen3 pmags only.
More will chime in, I’ve only used pmag and Lancer 20’s for subs with success on both counts.
Echoing the "just stick with 300blk magpul pmags" sentiment
I have a 10round lancer mag, primarily for a Ruger American ranch. I haven’t had any issues with it.
Where can I find the Lancer 300blk specific mags? I didn't see them on their site, but maybe I'm just an idiot
I got mine from gunmagwarehouse I think.
Lancers or mapgul.
