Re: Bubble level for rifle
I've found this with the one example of the Brownell's type that I own. If I level the rifle with a carpenter's level across the flat of the picatinny rail, the Brownell's level is off by 1/4 bubble. Looks like the tube is misaligned with the mounting screw or something.
I think I like the mount-on-scope style so I can precisely level and square the R2 reticle.
