Good luck with the m1a. Might I suggest against it? What about a ptr91? What do they call it, a 51? 308 loses big when sbr. Check out m14forum.com for info on sbr m1a.
Do the m92 first. Ace adapter, manticore triangle folder. If the Evo stocks get approved for import, do the Evo then. Don't skimp on nfa stuff as its a lifelong investment.
