Rifle Scopes: Expert Advice from Ryan Cleckner

This guide details the installation and zeroing process for the Monstrum Tactical Challenger 6-24x50 FFP scope, emphasizing its Flat Dark Earth finish and features like a zero stop, locking windage turret, and side parallax adjustment. The speaker, an experienced shooter, highlights the scope's value for long-range shooting and its smooth zoom lever, a refinement over previous generations. Proper mounting, parallax adjustment, and turret manipulation are covered for achieving accurate zero at various distances.

This guide details how to use the Longshot LR3 Ultra HD target camera system for efficient firearm zeroing. The system allows shooters to monitor shots remotely via a smartphone or tablet, eliminating the need to walk downrange. Key features include adjustable grid overlays for precise measurement, shot marking, and integrated recording capabilities, significantly simplifying the zeroing process for various optics and firearms.

This video provides an in-depth review of the Discovery Optics DGSM Heavy Duty Scope Mount. The mount is constructed from a solid chunk of 6061 aluminum, featuring a robust design with six torque screws per ring (rated at 25 inch-pounds) and four larger base screws (rated at 30 inch-pounds) with locking washers. It includes two recoil lugs and a removable "diving board" for accessories, along with an integrated bubble level. The review highlights its suitability for heavy recoil cartridges and long-range precision shooting, noting its substantial weight.

This review covers the EZShoot 5-25x56 FFP scope, highlighting its affordability and performance for long-range shooting. The instructor demonstrates mounting, zeroing, and shooting at distances up to 1000 yards, noting the scope's features like a 34mm tube, zero stop, and resettable turrets. Despite its budget price point, the scope proved capable of reaching extended ranges on a hunting rifle.

This video explains the fundamental differences between Minute of Angle (MOA) and Milliradian (MIL) for rifle scope adjustments. It clarifies that MOA is 1/60th of a degree, equating to approximately 1 inch at 100 yards, while MIL is 1/6400th of a circle, approximately 10 cm at 100 meters. The speaker notes that while reticles and turrets can be mixed (e.g., MIL reticle with MOA turrets), understanding the angular measurement is key for accurate adjustments.

This video debunks the common claim of 'parallax-free' optics. It explains that any lens system involving light refraction will inherently have some parallax. The degree of parallax increases with higher magnification. While manufacturers can reduce parallax, it cannot be entirely eliminated. Parallax is defined as the apparent shift of a target relative to the reticle when the observer's eye position changes.

This drill, demonstrated by Adam Painchaud from SIG SAUER Academy, focuses on improving pistol accuracy by isolating trigger anticipation. By firing a single live round and immediately following with a dry fire reset, shooters can identify and correct muzzle movement caused by flinching or anticipating recoil. Practicing this at distance, like 40 yards, provides clear feedback on accuracy and trigger control.

This guide, presented by former sniper Ryan Cleckner, breaks down the critical concept of Minute of Angle (MOA) for long-range rifle shooting. It explains how MOA is an angular measurement that increases in linear value with distance, crucial for understanding bullet drop and making accurate scope adjustments. The instruction emphasizes calculating MOA at specific ranges and converting these to scope clicks for precise zeroing.

This guide synthesizes expert instruction from Ryan Cleckner on fundamental long-range rifle shooting techniques. Key areas covered include achieving stability in the prone position, proper scope alignment to avoid 'scope shadow,' focusing on the reticle for sight picture, and executing precise trigger control with follow-through. Cleckner, a recognized industry expert and former Army Ranger sniper, emphasizes these core principles for accurate long-range engagement.

Ryan Cleckner, a former Sniper Team Leader, provides expert instruction on mounting a rifle scope. This guide covers essential steps from safety checks to final adjustments, emphasizing personalized fit for optimal performance. Key takeaways include proper ring placement, achieving correct eye relief and cheek weld, leveling the scope, and focusing the reticle for individual vision.
