Actually Princess that's not a .22 It's a Sig Sauer M400 (2nd in Background) loaded with 5.56 Green Tip N.A.T.O rounds. It can also use a slidefire stock that allows you to empty that 30 round mag in about 2 seconds or use controlled burst firing.
It will get the mofos attention but obviously the 50 cal puts the fear of God in. I can do 6 inch groups at 120 yards with the 50 using the mech sight on it.
My personal fav is the Sagia 12 gauge simi auto loaded with 00 Mags you see in the foreground.. that gets things going and is my goto WTSHTF!
I got it one piece at a time, and it didn't cost me a dime
