D D 1. THIS THREADING GUIDE CONTAINS DATA FOR THREADING FIREARM BARRELS THAT WILL BE COMPATIBLE WITH ALL CURRENT PRODUCTION ADVANCED ARMAMENT SILENCERS AND MUZZLE DEVICES. MANY OF THE THREAD SPECIFICATIONS HEREIN WILL ALSO BE COMPATIBLE WITH OTHER MANUFACTURER'S SILENCERS AND MUZZLE DEVICES. IT IS THE RESPONSIBILITY OF THE READER TO DETERMINE IF THE SPECIFICATIONS IN THIS THREADING GUIDE WILL WORK WITH OTHER MANUFACTURER'S PRODUCTS. ADVANCED ARMAMENT DENIES ANY LIABILITY FOR PROPERTY DAMAGE, PERSONAL INJURY, AND/OR DEATH CAUSED BY INCOMPATIBILITY BETWEEN THE THREAD SPECIFICATIONS IN THIS GUIDE AND ANOTHER MANUFACTURER'S PRODUCTS. 2. ALL MUZZLE PROFILING AND THREADING SHOULD BE PERFORMED IN A LATHE. C 3. ALL THREADS AND COAXIAL FEATURES MUST ALIGN CONCENTRICALLY WITH THE BORE AXIS OF THE BARREL. A C MISMATCH OFTHE BARREL BORE AND SILENCER/MUZZLE DEVICE MAY LEAD TO PROPERTY DAMAGE, PERSONAL INJURY, AND/OR DEATH. 4. THE BARREL THREADS MUST BE MACHINED TO THE SPECIFICATIONS IN THIS THREAD GUIDE. THE USE OF AN IMPROPERLY THREADED BARREL WITH AN ADVANCED ARMAMENT SILENCER MAY LEAD TO PROPERTY DAMAGE, PERSONAL INJURY, AND/OR DEATH. 5. IF THE HOST FIREARM BARREL IS SHORTENED, IT WILL BE NECESSARY TO RE-CROWN THE MUZZLE FACE. FAILURE TO RECROWN THE MUZZLE FACE CAN RESULT IN AN UNSTABLE PROJECTILE LEAVING THE MUZZLE B WHICH CAN RESULT IN PROPERTY DAMAGE, PERSONAL INJURY, AND/OR DEATH. B 6. IF THERE ARE ANY QUESTIONS PERTAINING TO THE INFORMATION FOUND IN THIS THREAD GUIDE, PLEASE CONTACT ADVANCED ARMAMENT AT 770-925-9988.
