History, development, & technology

TS, as in True Strength®, is the signature scope construction platform of Leapers UTG® optics. As the name suggests, no matter if it's a full size or compact scope, magnifier or dot sight, we aim to achieve the highest dependability starting at the heart of our scopes' structure. The research and development of this innovative structure was initiated in 2001 and in 2002 the first TS Platform scope was put into mass production. With our continuous testing, verification, and multiple rounds of improvement, we started promoting and selling TS optics on a global scale in 2005. Today, all our optics are built on the tough TS Platform to include a one-piece integral aluminum main tube, meticulously placed reinforcements at key structural points, and nitrogen purging to achieve optimal rainproof, fogproof, and shockproof performance even in the most challenging of scenarios. This superior TS Platform has even been adopted into the lineup of UTG® laser products, giving them precise and secure adjustment.


  • The Smart Spherical Structure (SSS) is one of the most significant characteristics of the TS Platform.
  • SSS simulates the human joint structure to achieve the utmost precision and reliability.
  • The erector tube is constrained via a ball and socket structural relationship, which provides the desirable flexibility to respond to windage and elevation adjustments and the optimal ability to hold zero under heavy recoil.


  • Reduces and Absorbs Recoil, Alleviating Potential Loss of Zero
  • Fully Tested on Both Air Rifles and Firearms
  • TS Technology Implemented in Every Leapers Scope


  • The Most Advanced and User-friendly Windage and Elevation Adjustment System with Innovative Design, Precision Components, and Disciplined Assembly
  • UTG®'s Leaf Spring System is Made from a Special Heat Treated Beryllium Bronze Alloy to Maintain Reliable and Consistent Long Term Tension
  • ACCUSHOT® Models Equipped with a Rugged Coil Erector Return Spring System For Improved Zero Hold Under Heavy Recoil and Greater Windage/Elevation Adjustment Range


The crosshair has multiple dots spread equally along the X and Y axis. The distance between two adjacent marks subtends to 1 milli-radian. The traditional wire reticle is robust and holds up against strong recoil and offers a clear aiming reference without compromise.


Leapers/UTG started introducing mil-dot reticle optics from as early as 2003, pioneering the Range Estimating concept as a useful tool for hunters and shooters around the world. Today, mil-dot reticle is widely accepted and used in this industry. Leveraging our years of experience in this area, we developed and refined the unique Tactical Range Estimating(TRE) mil-dot reticle and offer this feature in almost all of our optics. With some patient learning and practice using our TRE, shooters can enhance accuracy and performance in ways not imagined before.

9 Dot TRE Mil-Dot:
Nine dots are featured spanning each side of the reticle's origin in the left, right, up, and down directions. These provide 18 points of aim across for both windage and elevation. When including the reticle's origin and the inner edges of the reticle's outer duplex a total of 21 points of aim are available.

6 Dot TRE Mil-Dot:
Six dots are featured spanning each side of the reticle's origin in the left, right, up, and down directions. These provide 12 points of aim across for both windage and elevation. When including the reticle's origin and the inner edges of the reticle's outer duplex a total of 15 points of aim are available.

4 DOT TRE Mil-Dot:
Four dots are featured spanning each side of the reticle's origin in the left, right, up, and down directions. These provide 8 points of aim across for both windage and elevation. When including the reticle's origin and the inner edges of the reticle's outer duplex a total of 11 points of aim are available. For 4 DOT TRE Mil-dot scopes with a floating reticle, sans the outer duplex, a total of 9 points of aim are available.


1. Range estimating requires common knowledge/experience about your target's actual width or height.
2. Set your scope at 10X or the proper power, depending on the scope. View the target through the scope. Place the center of the dot against one edge of the target and measure to the opposite edge of the target.

3. Once the target has been measured in mils, depending on the scope model, a formula is available to estimate the distance of the target.
4. Each scope will come with a pre-calculated mil-dot table of most used distance estimates to aid the user.


For example, based on past experiences, the length of a known animal from shoulder to tail is 40 inches (1.016 meters), and we see through a scope at, for example, 9X to find that the animal occupies 9 mils. Therefore, the distance can be derived from using the following formula:

Hence, (1.016 x 1,000/9) X (9/10 ) = 101.6 meters (110 yds).
Armed with this knowledge, you can compensate for the bullet’s drop accordingly and make “great things happen”!
