Hey guy's this is my first time posting on ar-15.com, so bear with me. I have a dpms DCM (competition model), and it is incredibly acurate. I used to compete, but those days are long gone now. I have tried fitting optics to the rifle, via carrying handle mount, and it sucks. Scope sits way to high, and the evelvation only really works for one distance. I want to go varmit hunting, so I am looking for a decent varmit upper, (1 moa or better), any recomendations? A fellow over at ak-47.net recomened I look at j&t distributing, and ask around here. I looked through j&t's catalog and thier prices seem too good to be true, the upper I'm looking at is the 24 bull barreled upper on page 17 (374$) of thier online catalog. What do you guys think? , oh and if I buy the upper assembly without bolt carrier, and bolt, will I have to worry about headspacing issues with the bolt from my dpms, with my new Barrel? Thanks guys.
