7.62x39 AR15 platform

Hey guys, First time posting on the forum. I usually just read and get ideas etc. I’m wanting to do my next build in 7.62x39. I’ve read about guys having issues with the caliber in the AR platform. I’ve seen guys talking about enhanced firing pins, certain mags are better than others, use a heavy hammer spring etc. Can anyone share their experience with the 7.62x39 ARs? Tips, things not to do, things to avoid etc. Thanks in advance!
