Tangent Theta TT315M 3-15x50 Riflescope - GEN 3 XR Reticle
Features
- Premium Low‑Light Optics – Fully multi‑coated high‑definition glass and a 50 mm objective deliver exceptional light transmission and edge‑to‑edge clarity in dawn/dusk conditions.
- First‑Focal‑Plane Gen 3 XR Reticle – True‑subtension XR reticle remains accurate at any magnification for rapid ranging and hold‑over; illuminated with 11 brightness levels, auto‑off after 6 hours.
- Tactical Zero‑Stop Turrets – 30 mm exposed, lockable elevation and windage turrets with free‑spinning caps to prevent accidental drift; zero‑stop lets you return instantly to your zero, and turrets are re‑indexable without tools.
- Side Parallax / Focus – Side‑mounted focus knob adjustable from 50 m to infinity ensures a crisp reticle image and eliminates parallax error across all engagement distances.
- Rugged 30 mm Chassis – One‑piece aircraft‑grade aluminum tube with matte‑black Type II hard‑anodized finish, full O‑ring sealing, and nitrogen purging for IPX7 waterproof and fog‑proof performance.
- Versatile Magnification Range – 3×–15× zoom offers flexibility for close‑range acquisition to long‑range precision shots.
