I have had several AR,s in the past from various makers but right now the stable is empty. I have always wanted to collect some good stuff and have an AR built. I got in on the lower group buy that CCA is having on the Seekins lower they are going to make for them. I will be getting a lower, upper and a rail and have in mind what other parts i would like to use. The 1 thing i am not sure about is who,s bolt carrier group to use. I know Les Baer stuff is not cheap but have always thought that is stuff is top of the line. Would like to know what you guys think about using his comeplete bolt carrier group for the project. I will be using this rifle mainly to varmint hunt and bust some coyotes. Also not sure as to what cartridge i would like to use for the build as their seems to be quite a few to use besides the 223. Did some looking around and a fellow by Robert Whitley i believe does alot in other various calibers. What are you fellows using and any opinions would be a big help.
