If I wanted to have a clone built, which compliance parts are most commonly used, and what source if any other than Top Notch?  I'm guessing you begin with a US receiver, how many more parts are needed?  Trying to decide between a Bobcat FSA with the short barrel and pinned canned (when I move to a Class 3 state have it SBRed) or whether to go the build route.  POF hasn't had kits for awhile and who knows when more might be available.  Ideas my HK gurus?

Thanks, looks like the prce of buying parts and having a build done is going to be a lot more than a manufactured rifle.  

NY, no go... we still have the weight limit in effect.
