Chicago,
I also observed the 'doubled' checkering or 'mismatch' of the lines or whatever you want to call it, on my friend's RBL. It was as bad as the worst amatuer checkering attempt I've seen. All burned black and virtually a collage of lines with most of the diamonds non existant.
The 'engraving' was not as bad as the checkering, but looked like it had been buffed in an attempt to coverup poorly executed work.
I'm really disappointed that they put out a gun like this. It would have been more acceptable to the market, IMO, to have put out the gun as an unengraved model. The checkering debacle is a mystery to me, since Builder and I got a demo of the laser checkering machine on a RBL forend,which turned out nearly perfect (except for the burnt look). Truly disappointing.
