I've seen lots of guys (not here) selling 5 of each mag. Sorry to see Magpul's good will misused. Either way more mags on the streets. My friend that is recently into ARs got his air lift pack and is thinking of doubling his money. Funny thing is before his Magpul purchase he only had six mags. Does he think 16 mags will last him till he leaves the state? Assuming he doesn't sell his Boulder airlift mags.
