Then on Kak’s website, they posted a phone call basically saying the same? I notice the link on KAK’s website is now gone and they just post a letter from 2014. Frankly it still seems like shouldering a brace will land you in trouble if a bored ATF agent sees you do it. I almost feel like the rules are no shouldering of braces period, but sellers/wishful thinkers try to skirt the rules leading to fake information/confusion.
