Definitely. Makes sense to have 'more than necessary', whatever that number is. At the beginning of the 94-04 ban I only had probably 8-12 AR mags. Objectively more than really 'enough', but no way to know during those ten years whether the ban would actually sunset or not. Not again.
I much prefer the plain GI aluminum mags for serious use. Other than magpul followers, I don't really care about upgrades beyond that. Last ones I bought were NHMTG with magpul followers, cost $9 something. That was back in may of last year iirc.
