Just bought an Colt AR (it did not come with a magazine). I'm up to speed with the capacity issues from a legal perspective, so this is not a question on how many rounds I can fit into a magazine. I'm looking at MAGPUL PMAGS and my question is simply given all sizes are pinned to 5 rounds, is there a benefit to buying a 5/10 ,5/20 or 5/30? It would seem that if one could save a few bucks on a smaller mag why would you not always buy the smallest size available? Is the appeal of larger mags aesthetic, or is there some other benefit I am missing?
Would be great if I could find stock too...
