My buddy has a C93 that has gone back to Century 3 times now, He got it back this week and now it doesn't eject very well he said that the cases seem to barely clear the port. He can only get four or five shots before it doesn't eject the spent case and tries to load an new round with the spent one. He tried cleaning it and it seemed to make it worse, tried different mags and 3 different kinds of ammo. what could this be?

Check your bolt gap. This could be the cause.

At the minimum, your bolt gap should be around .004. Use a spark plug gap measuring tool to determine your bolt gap. Adding "plus" sized rollers will widen your gap, as will adding a new locking piece and/or repressing your barrel.  My C93 only has .003 gap, but it ejects just fine, and it also ejected just fine with "0" bolt gap with .223 PMC and Remington, Xm193, and Wolf. You may have a worn extractor/spring. I replaced the rollers on mine with +2 and it didn't help a whole lot, guess next I'll be putting in +4 and a new locking piece. These guns' gap are hit or miss, as the parts are all worn out military surplus. However, fit and finish are fantastic on these guns.

I went to the +4 rollers and they did good things. I am still going to do a new locking piece,  extractor and spring to make me feel better.

I just got some good info. Check the locking piece for a number that is stamped on one of the flat sides. if there is a 8 like on mine you might want want to order a 3. The 8 takes a hotter load and if you like to shoot the cheaper ammo you need a 3.
