I picked up my SOG CETME at the FFL yesterday. After taking a couple hours to clean (and figure out how to take apart) it didn't look too bad. However, it must have been stored with a coat of oil and a couple cups of dirt and grime.
It has a stamped Century receiver that was obviously made by trained monkeys. I say trained because it appears to be solid at the weld points. I say monkeys because the weld job is sloppy!
After running the action about 50 times it started to work itself in. I loaded some snap caps in a mag and it would chamber and extract them with no problem on both of the mags I received. Oh....the two twenty round mags I received look like new. It also came with a five round mag that also looked new.
The wood is obviously field used surplus. No cracks found, but several scratches, dents, and so on. Some Murphy's Oil Soap cleaned it up enough for me for now. I plan on adding a green plastic stock set to it anyway for that G3 look.
I shot only 20 rounds from it today off hand standing on my porch. I shot at dirt clods in the field next to me at approximately 100 yards. From what I can tell it appears to be pretty close to being on. I had zero problems with that first twenty rounds.
The CETME is a brass projectile machine. You could be shooting a target at 50 yards and hit another target at 15 yards with the brass. It was ejecting it 15 yards to the right front of me. Oh, the brass also comes out looking like crap. The chamber of the CETME has grooves in it (someone probably has the correct name.) It marks up the brass pretty bad.
Overall....I am happy with it. Heck, for $299 you can't go wrong. It goes bang when I pull the trigger and it appears that it will hold together (will send another report after I shoot 500 rounds through it.)
