Mags used from ASC (my personal fav) and c-products in 20 & 30 rounders work perfectly...

now the 74 is a whole nother story
Luckily I have no interest in 5.45 since it isnt dirt cheap anymore.

So where are these firing pins you speak of? The plan was to basically get something from PSA either the complete gun or a, upper and lower and put them together ans swap the bolt out for either the LMT or the young manufacturing, if I need to.
