What ar15 magazines are yall using

[Bear]

Hi, as the question suggests, I'm just looking for tips on what mags run the best for 6 arc in an ar15. Just wrapping up my build. I have a bunch of magpul 5.56 pmags I use for work, can I use them stock or maybe just a new follower? Or would I just be better off buying something else, and if so what do you recommend?

I’m new to this 6 mm arc rd not new to ars just finished building three ars in 6 mm arc and had bought 6.5 Grendel mags from Elanders 15 or 17 rd don’t remember but didn’t have a lot of luck with them the spring is awfully strong in them! Then I bought some ASC 15 red they work fine, I loaded the Elanders mags full with ammo and I will leave them set three or four weeks and then see if they will work!
