Maybe my opinion is skewed by my experience here in Georgia. As of late it’s been all about silencers and SBRs.
A lot of that has to do with the availability of them. The Hughes Amendment created a situation where MG’s are not commonly held because of the ban. Get rid of that ban and you’ll see massive numbers of MG’s being owned legally. As it is now, there’s several times the number of contraband MG’s in the US vs. legally owned and registered ones. The Hughes Amendment has created a very interesting situation that will result in the destruction of the NFA before long.
