I slightly regret selling my p90. TM, high ROF, could play all day with it without tiring my arms. The main reason I sold it? Mag choices. Only left with the 68 rnd mags which weren't that easy to get because of fake rounds, or the high caps which were complete garbage.
And now, just a few short months after, a company comes out with full black mags (so they're good to import yourself) which are 130 round mid caps. GODDAMN YOU WORLD!
EDIT: nvm, not black mags, but clear dark plastic.
