Since moving to the great free state of NH, I've replaced all my 10 round mags with 12-15 rounders, and am almost done with my evil Saiga 12 conversion and now I have my sights set on the obligatory AR. My question is, as never having built a gun from the ground up, should I buy a prebuilt RAA/Yankee Hill 6.8SPC and replace parts as I go along to my liking, or should I just start out with a stripped lower and go from there? Any input would be appreciated!
