Pretty amazing. I like the little detail on the magazine tube. Made me chuckle for some reason. The grip cap is pretty nice too.

It looks like the engraving panels get pretty deep in some places. Is there any risk of structural strength? I don't know the innards of an M12, but those areas don't look especially vital to strength but still looks like a lot of missing metal - enough to even make a significant weight difference, perhaps.

Cool gun, for sure. If there is no engraving on the barrel, I'd be tempted to find another barrel for it to do away with the Cutts.

Have you tried to letter the gun?
