Another new guy!

Keith here, I just purchased my second AR type, the first being bought and sold in the 80's. I'm an HK guy who's decided it's time to try domestic.
My new friend is a DPMS LR8C.. quite a nice piece. With the glass the first groups were 2" at 200 meters using Radway Green (don't tell anyone!) Not bad for a new weapon and an unfamiliar driver with surplus ammo. I'm excited to get serious with the new rifle (needs a bipod). I think it's time get the good stuff out and see if it'll beat the HK91.
