Went to Bullseye this weekend and picked up a Knights Armaments SR-15 and a Sig P220 Dark Elite. I love the SR-15! I took it to the range after putting a Aimpoint CompM4 and zeroed it in. It was one of the more impressive AR-15 style rifles I have ever shot. It is like, feels good and I had no problems with it.
The Sig P220 is just like every other Sig I own: amazing.
