Rear BUIS problem.

[sneakerd]

I have a YHM "build". Purchased a complete built lower and a factory complete upper with the 14.5" barrel, pinned Phantom MB and free-float barrel. Integral flip-up YHM front sight. I bought a $55 YHM steel rear BUIS off GB, have to dial it quite a few clicks off center to the left before my shots print in the bullseye. No issue when I had a GGG BUIS on there. Ideas?

is the integral front flip up attached with taper pins, or hex screws as normally seen?

If its hex screws, then just line up the front sight properly, it may not have been properly clocked at the factory.

The entire front sight, base etc assembly is attached to the barrel with 4 hex screws. It appears that it may be very slightly off center. Yu Da Man! I'll screw with it a touch and we'll see. Later.
