I also posed this question in the Clone section, but thought it would be applicable in this section also.
If you applied for and received your tax stamp for a SBR on an MKE 94A2 Rifle such as those currently
being sold by HK Specialist, wouldn't you be able to legally convert the mag well configuration without
installing 922r compliance parts, since at this point it would be an NFA SBR?
Thanks for your help!
