The ‘c’ stocks with the pistol grip look the best to me. I did some caliper measurements and the only way that my krag bayonet would work is with machine work on the cut 03 bbl to make it smaller. But I do have my spanish mauser bayonet that is actually pretty close in the lock and bore but is a little long in the body. I trimmed the lock and opened up the bore so it goes on fine except for just barely catching the too long bbl. More tinkering tomorrow.
