It was posted many times, a C93 is a parts set you can shoot. Back when the parts sets were readily available they were $400 and a SW93 receiver was $125 to $175. Very early guns were good. Century changed the barrel specs to make pressing the barrels easier to do. Problem was with less friction between the trunnion and the smaller diameter barrel, the barrel pins were not able to hold the barrel so the bolt gap would go away. I have one such C93. At least mine didn't have the bolt face ground. I have a 16" CHF Rim Country barrel. Some day I will get the barrel replaced, add a paddle mag release, and get it switched to use AR mags like all the other 5.56X45 host guns I have. Either that or I'll have a 33 clone built using a SW93 AR receiver I have tucked away.
