Any SAR-8 or similar experts on here? I have an SAR-8 Sportster made in Greece. It is not an overstamp. It has a serial number below 10000. From what I could find, rifles with serial numbers below 10000 have threads underneath the muzzle device. The muzzle device does not appear to be pinned from what I can tell. It looks like it may be able to be unscrewed. I haven't tried because I'd like to get some more info first. I have a Dead Air Sandman S in NFA jail right now. My goal would be to put on a Dead Air flash hider so I can shoot it suppressed. Also, does any one know if this rifle would be subject to 922r compliance? If so, would that change if I pinned the flash hider? I bought it used so I don't know what parts are US parts. What are my options as for pistol grip and butt stock as opposed to a thumbhole stock? I'd like to at least attempt to be legal.
