I don't compete, all I do is play at the range with my AR's and in the bush with my other toys.
All I'm trying to show is that you don't need a heavy barrel to shoot tight groups and to the OP that just because the DPMS barrel says it's a heavy contour doesn't mean that it is a target barrel. It's about the quality of the blank the barrel is made from not the contour it's finished in that determines what kind of accuracy you will get.
Let's see some pics.
LOL, had to open it back up, I only read the description the first time not the title.
Check out my latest threads. Pics are there.
