Holosun IRIS Reviews

Nice Unit

By Jason
Rated 4 out of 5
Date: 2025-12-04

It's A Well Built Unit, Vis Laser Is Nice, IR Laser And Flood Is Acceptable For Most Users. Not Able To Test The Spot (narrow) IR Illuminator At Distance Yet. Currently Only Complaint Is The Small Selector Lever Is Hard To Access When The Tape Switch Plugs Are Installed, But Its Not Unusable, Just Takes Some Effort. White Light Is Nicer Than My Surefire Scout 600 Surprisingly. The Tape Switch Is Nice And Has Positive And Tactile Feel, But Made For Rail Mount Only, So For Side Of Handguard You May Need An Add-on Rail And That Adds A Lot Of Bulk. I Am Going To Look Into A Different Tape Switch Only For That Reason.
