And while we are on the subject of what's legal on about action, what about all the rifles I see in the racks that come with muzzle brakes already installed. Do these need to be registered?
Wouldn't those 127 neighborhoods and the land they are located on go back to the states, Virginia and Maryland, that originally ceded the land to create Washington DC?
I like the Walker's Razor slim electronic ear muffs, usually run around $60 give or take.
I find that I have to double up my ear protection at an indoor range, plugs and muffs.
