Good magnifier with good price - Bushnell AR Optics 3x Magnifier

Got it for my TRS25 with UTG 1" riser and fits very nicely. Saw few reviews saying the unit makes the red dot slightly fuzzy but my setup is crystal clear. Brought it rear-most on the rail, almost touching the red dot, with MBUS rear sight tucked under on last tooth - eye relief is almost perfect, wish it was little longer but that's my personal taste! Tiny gripe I have with the unit: the center line is ever so slightly off it seems, could be the way I installed. It's on the hair width left of my red dot. Pull to flip mount is abit sticky but I suspect it will smooth out after few hundred flips.
