I never had one of the old ones, though I drooled over it a lot (his was the first good one!). I'm wasn't aware of the round knurl at the time, so not certain, but I'm pretty sure that the engraving looked like the one pictured on his site. This is a bit of a bummer, his flash hider, bull barrel, and scope mount are my favorites. I'd guess that maybe they've switched manufacturers? The crooked knurl is a major bummer, you should write to them about it, I'll bet they'll replace it (unless they're all like that), they've done similarly for me in the past.
