Since it's not a bottle neck they do require a different mag.

There have been a couple threads on the AR running 350. I don’t recall all of the advice/problems but my two big takeaways was trim the cartridge retaining lips on the mag back 1/4 to 5/16 back and use a barrel with a very generous ramp , as in wide open with no guide in the middle. My 350 works perfectly. GL

Aware of the mag issues. Just wasn’t sure of the bolt. I did a 6.5 Grendel and it required a specific bolt face
