5 backs 3 fronts that vary in length
0.682, 0.685, 0.688, 0.691, 0.693
backs are about 4"-5" inch long
fronts vary so you can get 12" 14" or 16" barrel lengths
I've got a cocker threaded version of the 8 piece kit - very good kit but hard to get hold of in the UK in Cocker threads. Very few barrel breaks and if one does go they clean out after a few shots.
