Choosing the right scope mount is crucial for any serious shooter. A quick detach (QD) scope mount offers the convenience of rapid removal and reattachment of your optic, but the key feature many seek is return-to-zero (RTZ) capability. This ensures your scope remains perfectly aligned after removal and reinstallation, saving you valuable time and frustration at the range or in the field. This guide will delve into the intricacies of QD scope mounts with RTZ, helping you choose the best option for your needs.
Understanding Return-to-Zero (RTZ) in QD Scope Mounts
Return-to-zero functionality means that after removing and reattaching your scope, the point of impact (POI) on your target remains consistent. This is not an inherent characteristic of all QD mounts; the quality of the mechanism and manufacturing precision are key factors. Low-quality mounts may shift slightly, requiring re-zeroing after each removal. High-quality RTZ mounts, however, use robust locking mechanisms and precise machining to maintain zero.
How RTZ Works: A Closer Look
Several mechanisms contribute to a mount's RTZ capabilities:
-
Locking Lever Design: A robust and precisely engineered lever system is essential. Poorly designed levers can introduce stress and misalignment. Look for levers that provide a firm, positive locking action.
-
Clamp Design: The clamping mechanism securing the scope to the mount must be strong enough to prevent movement yet gentle enough not to damage the scope. Look for mounts with durable materials and even pressure distribution.
-
Manufacturing Precision: The overall manufacturing tolerances of the mount play a significant role. Inaccuracies in machining can lead to variations in alignment even with a robust locking system. Reputable brands known for precision manufacturing are key.
-
Material Quality: The material used in the construction of the mount affects its durability and ability to maintain zero. High-quality aluminum alloys are preferred for their strength and resistance to wear.
Types of Quick Detach Scope Mounts with RTZ
Several types of QD scope mounts offer return-to-zero functionality:
1. Lever-Based Mounts:
These are the most common type of QD mount. They use a lever mechanism to quickly attach and detach the scope. The quality of the lever and its locking mechanism are critical for RTZ performance.
2. Throw Lever Mounts:
These mounts often feature an even faster and more intuitive lever system for quick detachment. Many top-tier manufacturers offer throw lever mounts with excellent RTZ capabilities.
3. Picatinny/Weaver Rail Mounts:
The vast majority of QD scope mounts are designed to work with Picatinny or Weaver rails. These standardized rails ensure compatibility with a wide range of firearms and accessories.
Factors to Consider When Choosing a QD Scope Mount with RTZ
-
Your Rifle: Ensure the mount is compatible with your rifle's rail system (Picatinny or Weaver).
-
Your Scope: Verify the mount's ring size and overall dimensions are suitable for your scope.
-
Weight and Durability: Consider the weight and durability of the mount. A heavier mount might be more robust, but it could also impact the balance of your firearm.
-
Brand Reputation: Choose a reputable brand known for manufacturing high-quality, precise mounts.
-
Price: High-quality RTZ mounts tend to be more expensive than standard QD mounts, but the enhanced precision and reliability are often worth the investment.
Maintaining Your RTZ QD Scope Mount
Proper care and maintenance can prolong the lifespan and RTZ performance of your scope mount:
-
Regular Cleaning: Keep the mount clean and free of debris.
-
Proper Lubrication: Apply a light lubricant to the moving parts as recommended by the manufacturer.
-
Avoid Over-Tightening: Over-tightening can damage the mount or your scope. Tighten only to the manufacturer's specifications.
-
Storage: Store your firearm and scope in a safe and dry environment when not in use.
Conclusion
A quick detach scope mount with return-to-zero functionality is a valuable asset for any shooter. By understanding the key features and factors to consider, you can choose a mount that ensures consistent accuracy and a hassle-free shooting experience. Remember to prioritize quality and brand reputation for optimal performance and long-term reliability. Investing in a high-quality RTZ QD mount will significantly improve your shooting experience and reduce the frustration of re-zeroing after each removal.
