Description
Tangent Theta TT315M 3-15x50mm Marksman Riflescope Gen 3 XR Reticle
Tangent Theta 3-15x50mm model TT315M Rifle Telescope is an intermediate-range precision sighting instrument for police and security marksmen.
Designed as a reduced-weight professional marksman rifle telescope, the TT315M incorporates precise adjustment mechanisms with zero stops and mechanical revolution and windage direction indicators that virtually eliminate adjustment errors. The optical path has been optimized for unsurpassed image quality, allowing the marksman to see minute target detail and to remain in the aim for extended periods without eye fatigue.
FEATURES :
- 50mm objective lens
- 30mm main tube
- mechanical windage direction indicator
- eleven reticle illumination settings
- side parallax adjustment
- non-translating knobs with elevation zero-stop
- double-turn elevation with revolution and windage direction indicator
- 3-15x magnification range
- Lockable rapid adjusting diopter
The turrets also feature a zero-stop function, which allows the user to quickly return to a known range zero and to be able to use that setting as a starting point to make further adjustments. Another innovative feature on the turrets is the exclusive Tool-Less Re-Zero function. This allows the user to adjust the reading of the adjustments without changing the point of aim in the scope. The Tool-Less Re-Zero procedure is simple: just loosen the lock three turns, adjust the dial to zero, and while holding the dial at precisely zero, tighten the lock to “finger tight”. Other features of the TT315M include an advanced illumination system with 11 brightness settings. Each setting features a tactile detent with additional detents between each setting. The illumination detectives between each setting, and a 6-hour automatic shutoff preserves battery life.

Non-Translating Turrets – Dual turn elevation turret with upper and lower adjustment scales. Simplifies the act of making adjustments in the field as well as the overall operation of the scope
Zero-Stop Function – Allows the user to quickly return to a known range zero and to be able to use that setting as a starting point to make further adjustments
Tool-Less Re-Zero Function – Allows the user to adjust the reading of the adjustments without changing the point of aim in the scope

- 0.025 MRAD vertical and horizontal crosshairs give an ultra fine aiming point
- Full and half MRAD subtentions for rapid ranging and holdovers
- Full and half MRAD wind holds below the horizonal allow for compensation at distance
- Minimal holdover data allows a user to easily spot fall of shot
