Since it was apart I decided to clean it up in preparation of whatever spring kit I order for it. After cleaning out the grease i found a lump of braze in the top corner of the comp tube.
If you look carefully you'll see the edge of the transfer port is dented at 3:00. That's worse than you'd think.
Anyways here you can see along the 12:00 edge the dents the braze lump makes as the seal rotates during use.
This wasn't causing any problems yet because the gun wasn't used alot. This gun will perpetually eat seals, eventually diesel and lose efficiency. Krytox will eliminate the dieseling but won't prevent seal damage and the associated compression losses from it.
This isn't the first, second or even third time I've found sloppy brazes in Weihrauchs. There's no easy home fix for them. Most well equipped machine shops don't have the equipment to machine the corners of the bore without taking the tube over size.
Oh well. You win some. You lose some.
