Key Features
- Second Focal Plane (SFP) Reticle: Maintains the same visual size across all magnification levels, ideal for consistent aiming.
- Tactical Turrets: Exposed turrets for quick and precise adjustments.
- TMCQ (MOA) Reticle: Designed for accurate ranging and holdovers.
- Extra-low Dispersion (XD) Glass: Enhances resolution and color fidelity for crisp, sharp images.
- Proprietary Coatings: Multiple anti-reflective coatings on all air-to-glass surfaces for increased light transmission.
- Customizable Rotational Stop (CRS): Aids in returning to zero after temporary elevation corrections.
- Illuminated Reticle: Electronic illumination for improved visibility in low-light conditions, daylight visible.
- Shockproof & Waterproof: O-ring seals and argon gas purging ensure durability and performance in harsh environments.
Setup
Mounting the Riflescope
Securely mount the riflescope to your rifle using appropriate rings and bases. Ensure proper eye relief and alignment for comfortable and effective use. The scope is compatible with cantilever mounts.

Eyepiece Focus Adjustment
To ensure a sharp reticle image, adjust the eyepiece focus. Look through the scope at a plain, bright background (like a wall or the sky). Rotate the eyepiece adjustment ring until the reticle appears crisp and clear. This adjustment is crucial for preventing eye strain and ensuring accurate aiming.
Illumination Battery Installation
The illuminated reticle requires a battery. To install or replace the battery, unscrew the illumination control knob. Insert the battery with the positive (+) side facing outwards. Replace the cap, ensuring it is securely tightened to maintain waterproof performance. The illumination control offers 10 brightness settings with "off" positions between each setting.
Zeroing the Riflescope
After mounting, zero your riflescope at your desired distance. This involves adjusting the elevation and windage turrets to align your point of aim with your point of impact. The turrets feature 1/2 MOA clicks for precise adjustments. The Customizable Rotational Stop (CRS) system allows for a reliable return to your established zero.
Operating the Riflescope
Magnification Adjustment
The magnification adjustment ring allows you to change the power from 1x to 4x. The ring has aggressive knurling for a secure grip and a short throw for quick adjustments. A fiber optic rod on top indicates the current magnification setting, visible even when behind the gun.

Reticle Details (TMCQ MOA)
The TMCQ (MOA) reticle is located in the second focal plane, meaning its apparent size remains constant regardless of the magnification setting. This allows for consistent subtensions for ranging, holdovers, and windage corrections. The reticle features a fine crosshair with hash marks for precise aiming, and an illuminated center dot for low-light visibility.

Maintenance
Cleaning the Riflescope
The riflescope's smooth finish makes it easy to clean. Use a soft, lint-free cloth to wipe down the exterior. For lenses, use a lens brush to remove dust, then a lens cloth with a specialized lens cleaning solution. Avoid using harsh chemicals or abrasive materials that could damage the coatings.
General Care
Store the riflescope in a dry, cool place away from direct sunlight. When not in use, ensure lens caps are in place to protect the optics. Avoid dropping or subjecting the scope to severe impacts, although it is designed to be shockproof.
Troubleshooting
- Blurry Image: If the reticle or image appears blurry, first check and adjust the eyepiece focus. Ensure the eyepiece adjustment ring has not shifted due to recoil or accidental bumps.
- Illumination Not Working: Check the battery. Ensure it is correctly installed with the positive (+) side facing out and that it has sufficient charge.
- Turret Adjustments Inconsistent: Verify that the turret caps are securely tightened. For zero stop issues, ensure the shims are correctly installed and not causing excessive pressure or misalignment.
