Ok, shot show gave a short glimpse of these. Now, the MA3 appears close to the MA2 except sporting a laminate stock enabling a more rigid mount for bipod use, I believe it also has an external adjustable regulator- can’t swear to this. Ballpark 500ish. Now the MA8 looks to promote all sorts of bells and whistles, definitely external adjustable regulator, electronic trigger and other goodies. Price is rumored so I won’t comment. Thoughts?
