X,
Best loop hole I understand as of now is to go featureless or purchase bb reloaded or get a prince 50. I am planning to go featureless ala pinning my magpul stock or buying an a2 stock, put on a monsterman grip or other kydex wrap, remove flash hide, put on a brake, and remove bb for a std. mag release.
I'm trying to figure out how ammo purchases will affect me going out to shoot. I might have to start reloading but component's will be hard to get again.
