Lancers all the way for me. Solves the OP’s problem in regards to the dislike of polymer mags. Poly body, steel feed lips.
I noticed at work they have gone to those for the C8 qualifications. Previous it was just the Colt Canada GI mags. Gave them a quick look over. Looked good and worked great with tons of rounds being fired. No non purposely induced failures.
My goto for AR15 mags are the D&H mags. I find they work great and were inexpensive when I bought them (not so much now). Unfortunately I haven't seen them on sale for the AR10/AR308. I have a few gen 3 pmags but never been a huge fan of them. Two KAC SR25 mags but they are ridiculously expensive (especially for what they are). Which leaves some ACS 10 round pistol mags that seem decent. A few DPMS mags that are complete crap. When one doesn't even fit in the rifle it came with, you know it's crap.
Long story short. I'm looking for a decent SR25/AR10A mag. The Lancer mags look really good. A bit concerned about the cost though.... Might be sticking with pmags a while longer.
