I have/had 3 braced pistols. My primary use was as a "car gun": My 10.5" AR with Law folder. I want to still be able to carry this in the front of my car, concealed (for now) so I pulled the brace and put a tube back on it so I'm as "safe" as I can be from the ATF and local and state LEO's in a traffic stop. I will start experiment with slings now. I pulled the folding triangle brace off the PSA AK pistol and installed a two point bungee sling and a red dot. I think I like it better this way. We'll see how it shoots. The triangle brace was cool, but I didn't like it when actually shooting the gun. The 7.5" 7.62 x 39 upper will probably be sold off and the lower repurposed.
I toyed with the idea of the "free" tax stamps. The more I thought about it, I remember something my Dad said. "There ain't nothing in this life free, Son". Our last name is Beavers. Dad was a Marine (died 1994), Door gunner on a Chinook for 13 months in Vietnam. He experiences led him to not have much use or trust in our government (Federal). I don't want to play their (ATF's) game. You change the rules, so I'll try to work the loop holes harder. They will always win that game.
I'm not one of those guys who has the money to legally fight it.
