"The one built on a special weapons receiver...I'm not sure who built it...it came factory with a paddle mag release"
It is not like I've followed every C93 thread, but I haven't seen a C93 with a paddle mag release. I was thinking of sending my C93 to Mike Turner and having the receiver altered like the SW93 AR receivers. I'm originally an AR guy. I've got piles of AR mags and drums. Buying a whole other set of 5.56X45 mags for the HK roller locked system put the HK style 5.56 guns low on my list. Since Special Weapons put out the SW93 AR receivers, I've had much more interest in the roller locked 5.56 guns.
When I have the C93 modified to take AR mags, I'll have a paddle mag release done at the same time. Then of course it'll need a refinish. I still need to put some more rounds through my C93 to make sure there are no other issues before I spend all that money on it.
I've read a couple of different threads talking about how Century made the chamber end of the C93 barrels smaller than HK spec so the barrels would be easier to press in. Some have said that after a couple of hundred rounds the smaller diameter barrels would move. It doesn't take much barrel movement in the trunnion to throw the bolt gap out. I already have +2 rollers in it now.
I've been on the fence as to what to do. If I'm going to spend the money on the the receiver/AR mag modification with the paddle mag release, how much more would I end up spending on a barrel change? If I'm going to have all that done, would I be better off just using one of the extra CA93 AR receivers I have and a 33 parts kit? I could use one of the spare the Rim Country barrels from the two parts kits I plan to have 53 AR and 53K ARs made from. The 53s will have RCM hammer forged 53 barrels used in the build. Once the 33 clone with the SW93 AR receiver is built, switch the US made parts and sell the C93 barreled upper.
If the barrel is okay in the C93, then I'd think the AR mag receiver modification and paddle mag would be less expensive than a complete build. But once the modifications are done, I'll always be wondering about the barrel. I could have the barrel checked before doing the modifications. But what would that cost? There is some piece of mind for a custom build without having any work on the C93. Money is tight right now, so I'll just keep shooting the C93.
