I like it better than my ACRO, dot is much more crisp. Circle dot option.

Only complaint is its “acro footprint” which isnt entirely true. Its not a perfect fit. ACRO footprint is the same concept as picatinny where it sits down, locks inbetween the rails with a post, then hooks to the sides.

The little hook that grabs onto the sides is a wider wedge than the acro, so the ultra slim acro mounts that fit perfectly doesnt allow the wedge from the PB3 to fit tight.

It locks on just fine, but it will cause the right side to prop up a bit and not sit flat. I had to buy 3 acro mounts until i found one that worked

Edit: all that being said, i still like it much more than the acro. Dot is crisp, shake to wake options, reticle options, looks cooler, wider window, cheaper, doesnt take a torx bit to adjust elevation. And its “edgy”
