I picked up a colt 6920 from phoenixlawenforcement.com for $1120. I have been picking up components for it over the last few months and finally put it all together. I took it out to the range today to sight it in. With the aimpoint at 50yds, everything was about a 2in group. With the acog, everything at about 1/2 in groups.
