True when we had our bushmasters heck 10 years ago dam im almost 30 lol we had 6 mags two new mags that came with our bushmasters 4 surplus gi mags. Never had a issue with them. We left ours loaded 24/7 (I knew less then then I do now). Still no issues. Iv never cared much bout round count though either. Prob just go with whats price best I did find the magpul plastics for like 14 bucks I think it was though. Im more concern with feed issues then plastic or steel so might buy one plastic and see how the do. My buddy bought cheapo plastic for his ak47 while he had a 1-2 round ftl with his steel the plastic would ftl or ftj bout 3-5 rounds per mag but that ak was a pos he traded it for a nice 2000 dodge 1500 lol
