Should’ve started with this one….

Review by Alexander B. on 19 Sep 2025 review stating Should’ve started with this one….
This optic is good for someone starting out into mini red dots for handguns, piggy-backs or back ups. The foot print is in all reputable manufacturers products and can be tossed around to any build you wanna slap together and enhance with time.

I have to give it

Review by James A. on 18 Sep 2025 review stating I have to give it
I have to give it a 3 out of 5 stars. The hood of the barrel is showing serious signs of wear as it rubs the inside of the top of the slide. I'm not too concerned about esthetics as I am about function. I regularly compete in IDPA. When I have a stage where I need to shoot fast doubles at a longer distance (say, 15-20 yds) I sometimes get flyers. They (the Charlie's and Delta's) could be me, bug sometimes I know I'm calling my shots and they still fly 🪰 off my POA.

Pretty dope. Fits my Lead

Review by Joseph S. on 17 Sep 2025 review stating Pretty dope. Fits my Lead
Pretty dope. Fits my Lead and Steel PB3 pretty good, needed just a little filing on the front to get it to fit, but the PB3 is a little bigger than an ACRO.
