Customer Reviews
“The ACOG is incredibly rugged and performs well in low light. The RMR sight is a game-changer for quick shots.”
“Excellent clarity and easy adjustments. This kit is perfect for my tactical operations.”
“I love the versatility of this setup. The dual illumination works flawlessly in any condition.”
FAQ
How does the dual illumination work? The ACOG features fiber optics that gather ambient light during the day, while tritium provides illumination at night or in low-light conditions. This ensures a clear aiming point regardless of surroundings.
Is the RMR sight suitable for all lighting conditions? Yes, the automatic LED brightness adjustment in the RMR sight optimizes visibility in varying light conditions, making it adaptable for both bright and dim environments.
How does the ACOG compare to other scopes? Compared to traditional scopes, the ACOG offers fixed magnification for superior clarity and a robust design that withstands harsh conditions, making it ideal for tactical and competitive shooting.
What kind of maintenance is required? Regularly check for any loose screws and clean the lenses with a microfiber cloth. Avoid using harsh chemicals on the scope body to maintain its durability.
Can this kit be used for long-range shooting? While the ACOG 4x32 is designed for medium-range engagements, the clarity and precision it provides can still be beneficial for longer distances, especially with the first focal plane reticle.

Understanding Rifle Scope Basics
Magnification
Magnification refers to how much larger an object appears through the scope compared to the naked eye. Fixed power scopes have one magnification setting, while variable power scopes offer a range (e.g., 3-9x).
Objective Lens
The objective lens is the front lens that gathers light. Larger objective lenses (measured in mm) gather more light, providing brighter images in low-light conditions but add weight and require higher mounting.
Reticle
The reticle (crosshair) is the aiming point inside the scope. Modern scopes offer various reticle designs, from simple duplex crosshairs to complex ballistic reticles with holdover points for different distances.
Adjustments
Rifle scopes have turrets for windage (horizontal) and elevation (vertical) adjustments. These are measured in MOA (minutes of angle) or MRAD (milliradians) and allow precise aiming adjustments.
Proper Scope Mounting Guide
Select the Right Rings & Base
Choose rings that match your scope's tube diameter (typically 1", 30mm, or 34mm). Select a base compatible with your rifle's receiver. For heavy-recoiling rifles, opt for stronger mounts.
Install the Base
Clean the receiver and base thoroughly. Apply a small amount of blue Loctite to the screws. Attach the base to the receiver and torque the screws to manufacturer specifications.
Attach the Rings
Attach the bottom halves of the rings to the base. Place the scope in the rings and loosely attach the top halves. Don't fully tighten yet.
Set Eye Relief & Level
Position the scope for proper eye relief (3-4 inches) in your normal shooting position. Ensure the reticle is level using a scope leveling tool. Once positioned correctly, tighten the rings evenly in a cross-pattern.
Scope Zeroing Tips
Start Close
Begin zeroing at a shorter distance (25-50 yards) to ensure you're on paper before moving to your desired zero distance (typically 100 yards).
Use a Stable Rest
Always zero your rifle from a stable shooting position using a bench rest, sandbags, or a shooting rest to eliminate as much human error as possible.
Fire Groups
Fire 3-shot groups before making adjustments. This provides a more accurate representation of where your rifle is shooting than single shots.
Make Deliberate Adjustments
Know your scope's adjustment values (typically 1/4 MOA per click). If your group is 2 inches low at 100 yards, you'll need to adjust up 8 clicks (for a 1/4 MOA scope).
Confirm Your Zero
After making adjustments, fire another group to confirm your zero. Repeat the process until your point of impact matches your point of aim.
Document Your Settings
Once zeroed, record your settings including distance, ammunition used, and environmental conditions for future reference.
Optics Maintenance & Care
Cleaning Lenses
- Start by blowing or brushing away loose particles
