Mag release came with messed up threads, pivot pin doesn't fit PSA lowers

by -

Front pivot pin isn't long enough to fit PSA lowers. I get it, I understand there is no standard or mil spec for the AR10 platform. The mag release came with messed up threads, which is disappointing for what is supposed to be a premium LPK.
<br>Pass folks
<br>PA is awesome, they ship fast, hell they might even let me return this POS, but I'll just add whatever is left to spare parts bin, expensive few parts left at $60 for the kit
