Designed to mount directly behind a reflex sight or red dot, the versatile t-3 magnifier allows a quick and easy way to magnify your sight picture by 3x and provides an absolute co-witness.A straight tube magnifier a full.8" shorter than the model it replaces, the t-3 features a streamlined, low drag design, preventing the magnifier from snagging on equipment in important situations.Ideal for engagements up to 100 yards, if a close-range shooting scenario calls for no magnification, simply use the t-3's flip-to-side mount to rapidly transition between the optic systems.External windage and elevation adjustments align the reticle to the center of the t-3's point of view.Eotech and aimpoint compatible, the locking quick detach mount found on the t-3 lets the magnifier be quickly removed.Includes flip-to-side lqd mount, adjustment tools and manual.Magnification: 3xObjective: 23mmField Of View: 43.30 ft @ 100 Yds/ 14.43m @ 100 mEye Relief: 2.25"/57mmTube Diameter: 30mmLength: 4.0"/103 mmWeight: 10.60 ozFinish: Matte BlackProofs: IP55 Water Resistant/ ShockproofOptic Coating: Fully Multi-CoatedWindage Elevation: Adjustable
