NOTE: IMPORTANT
The black version caps which suits the 16 tpi with the 1 and 1/16th inch pitch (1-1/16″) threads are just that. So be aware that some Remington actions over the years have been customised and blueprinted by many gunsmiths. Certainly the PSECO ones done by John Giles in Australia mostly are. This means the threads in those actions were machined out slightly larger diameter to correct imperfections. Therefore the barrel threads were cut accordingly to match that slightly oversize result. This means the barrel caps (the black ones) will not fit those oversize threads because they are actually… oversize.

The amount of oversize also varies from one blueprinted action to another.  So if there is any doubt, measure the thread diameter properly. But another way, which is not the proper way to measure threads, but this way will give you a rough approximation and help you decide if these barrel caps might fit the threads on your barrels. Use calipers across the outer surface of the thread. If that shows larger than 1.0625″ (27mm) then this means it is oversize . See picture below which illustrates an oversize thread example.
