Hi-There "people" ! New to these new-fangled, hi-tech, inter-dweeb, blog things, but not new to firearms & shooting ! Thanks for letting me in ! Former military, current Corporate Exec. protection,I've been shooting almost everything since the '70's. Got my 1st Sig, a P220 .45 in the '80's, have a 516 scoped for 500yds and just assembled my first Short Barreled supressed rifle, an MCX with the short 300 Blackout & 556 barrels, each with the Sig SRD Ti-Qd "Mufflers", so of course I'm looking for any tips & info from anyone who has any time on one of these really modern & really fun toys, especially if they also set one up like mine. I will "glue-on" a photo if I can ever figure out how to do it !, Thanks again guys.
