Why disregard NFA stuff? It really is funner. And there's no law that says regular people can't shoot NFA weapons.
We're having a shoot this afternoon here in Utah that is just a friendly get together for local gun nuts.
We'll have -
Full Auto: PK, PKM, DP, RP-46, PPsH, MP5, M16, AK47, Uzi and more.
Suppressed: M4, various ARs, MP5, various pistols.
SBR/SBS: ARs, Krinkovs, and 12" and 8" Saiga 12s. (think of a 12 guage Krinkov)
Regular people will be able to play with all of these things, buy ammo, and shoot to their hearts content.
Now of course, this only applies to people who live in states that don't suck.
