These are the Generation 2 Dragon Head Brakes that have been designed by Black Hole and Tactical Ammunition. No release date or pricing yet but it will be soon. These brakes are threaded for 1/2 and 5/8 threads and will be able to handle most of the AR chamberings. The Gen 1's work extremely well and these, so I here , do the same. I'll be testing one shortly.
I have been waiting for this revamp for several months and I am looking forward to getting one in action.
