This is a new AR15 bolt modification that converts a semi-auto AR15 into a bolt-action. The Kalikey is fastened to the bolt carrier after removing the gas key, converting it into a bolt-action rifle. It should be CA compliant - does anyone think it will pass muster in NY? Converting the rifle back to a semi-auto requires either another traditional BCG, or the reinstallation of the gas key and a normal charging handle. I know the NYSP won't weigh in on this - I'm looking at the court of popular opinion right now...
