Larue BCG 5.56 vs 7.62, OBR vs. PredatOBR

[adamyq]

I received my Larue OBR 7.62 (supposed to be a 4+ month wait but turned out to be...10 days). I was amazed by the workmanship, particularly in the bolt carrier. Fit and finish was truly a work of art, very smooth assembly and cycling. I was expecting the exact same thing in my Larue PredatOBR 5.56 that I just received, but.....no. Don't get me wrong, the build quality is still really nice, on par with my LWRC rifles, but not on the same level as the OBR.

So my question is simple: Is there a difference between the OBR and PredatOBR BCGs? Or does the difference lie in the difference in the caliber?

I have each and can pull the BCGs when I get home. Is there something specific you want me to look for?

I can tell you my PredatOBR 7.62 is one of the smoothest cycling AR's I've handled out of hundreds. Smooth as glass. The extra attention and polishing on the bolt carrier group of the contact surfaces has to be what makes all the difference.

The difference lies in the caliber.
