Overview
A compact reflex sight built on the Doctor, Vortex Venom and Burris Fastfire mounting footprints, running a CR2032 battery with shake-awake standby and five brightness levels, offered in green or blue dot and black or tan finish.
Despite sitting under a Handgun Scopes category in this catalog, it's a red-dot style reflex sight, not a magnified scope, matching what the title and listing describe. Reviewers mounted it on a range of pistols, from a PSA Dagger to a Taurus TX22 to a Ruger Mark IV, with fit and results varying by gun and mounting plate combination.
- Compatible with Doctor, Vortex Venom and Burris Fastfire footprints
- CR2032 battery with shake-awake standby
- Five adjustable brightness levels
- Weighs 1.1 ounces
Who it's for
Fits handgun shooters with a compatible footprint cut who want a budget reflex sight for range use or casual competition. Not the pick for carry use given reported power cutouts, or for shooters who need a guaranteed sub-3 MOA dot.
What buyers say
From Amazon customer reviews.
Several reviewers reported the sight held zero through 200 or more rounds and fit cleanly on pistols including a PSA Dagger, a Vortex Venom base and a Taurus TX22, with one competition shooter saying it cut time off compared to iron sights. Two reviewers reported the unit randomly powering off during use, with one calling it unreliable for anything relying on it staying on. Others noted the dot measured larger than the advertised size or bloomed at higher brightness, and one buyer said the tan color read more copper-brown than true FDE.
