I have a 6x45 and a .264 LBC AR. The 6x45 has a 1/2x28 thread, the .264 LBC has a 5/8-24 thread. Both are BHW barrels. Would you get 1 can to share or 1 for each? If one to share, how with different threads? Threaded or quick disconnect? Is the length of the threaded part of all barrels standard? Can someone with knowledge on this help me? TIA
