This is my rifle, there are many like it, but this one is mine...
t6 stock, saw grip, g2 FCG, dinzag BG, UTG rails. I filed the mag release to take standard mags. I am having a hard time finding a gas block with the sights in it like the krebs KTR. When I find one I will install it, chop the barrel and weld on a j-tac so the barrel ends just a hair over 16" Then I will duracoat it all black. I did the conversion with my brother in a couple hours, was really easy.
I got it from classic arms and the hand pick was worth the $10 without a doubt. Dimpled receiver and a surplus barrel.
