I know I will need US parts on the gun when I go to make it look like a G36. But at the moment I was just wanting to replace the upper rail from the SL8 to the G36 rail. I am doing this because for some reason they did not put any sights on the stock rail and I would like to have a rail with iron sights on it.
I was wondering if I would need US parts if I just replace the upper rail?

Thanks in advance for info.

No. Things like the rail, sights, and forearm can be swapped out without needing US parts. 922r only kicks in when adding evil "non-sporting" features like folding stocks, pistol grips, hi-cap mags, etc.
