degree markings on 34 rec

[crash520]

Team,
has anyone seen markings like a +3* ( indicating +3 degree's) or +4* on the side, front and back of a 34 reciever at all??? I have one with such, cant post pics right now due to computer issues. Interestingly it has no serial number either, has an eagle stamp on it, finish and machine marks match my Brno rec exactly indicating to me that its of origin and not a current manufacture as such.

any info appreciated.

Yes, mine kit has a 5. Don't know what it means.

I'm intrigued, some photos would be great.

similar markings are on the back end of the rec beside the buffer release latch

Would these marks be how much the connecting post has been tightened to make a snug fit with the barrel jacket? There was a special tool and process for making a snug, but not too snug fit between the two parts.

that maybe the case, and I guess if it is then the marking on the back are for the buffer tightness??? maybe??
