yupper's, we sure can! i am waiting on a set of billet receiver's from our mega group buy, and i plan on registering the lower, ( previously unreleased info!) and doing two uppers dedicated to that lower, a 14.5" match in .223 wylde and a sbr of undetermined size as of yet. all you have to do is go to your local pd, fill out the paperwork, get the approval of your chief, pay the man, and wait for your stamp, then BAM, sbr baby <lmao> <thumbsup>
