The .45-70 Government cartridge, a powerhouse known for its stopping power, is seeing a resurgence in popularity. Whether you're hunting large game, participating in Cowboy Action Shooting, or simply appreciate its historical significance, enhancing your .45-70's accuracy and speed is crucial. A well-chosen red dot sight can significantly improve your shooting experience. This guide explores the best red dots for a .45-70, considering factors like recoil, mounting options, and overall performance.
Choosing the Right Red Dot for Your .45-70
The .45-70's substantial recoil presents a unique challenge when selecting a red dot sight. A robust, reliable optic is essential to withstand the punishment and maintain zero. Here's a breakdown of key factors to consider:
Recoil Resistance
The most crucial factor is recoil resistance. The .45-70's heavy recoil can quickly damage a poorly constructed red dot. Look for optics specifically designed for high-recoil rifles, featuring durable construction and robust mounting systems. Features like sealed housings and ruggedized lenses are also beneficial in protecting the sight from the elements and impacts.
Mounting Options
Your rifle's receiver and rail system dictate the available mounting options. Many .45-70 rifles utilize Picatinny or Weaver rails, while some older models might require custom solutions. Ensure the red dot you choose is compatible with your specific mounting system. A secure and stable mount is paramount for accuracy and longevity.
Lens Size and Clarity
Larger lenses offer a wider field of view, crucial for quick target acquisition. However, larger lenses can also be heavier and more susceptible to damage. Prioritize clarity and brightness, ensuring the dot remains visible under various lighting conditions. Consider a sight with adjustable brightness settings to cater to different environments.
Battery Life
Extended battery life is a must, especially for hunting or prolonged shooting sessions. Some red dots utilize incredibly energy-efficient technologies that can keep the sight powered up for months or even years on a single battery. Look for an indicator on the battery's status.
Features
While not essential, certain features can greatly enhance usability:
- Motion-activated illumination: The dot turns on when it senses movement and off when it's still, saving battery life.
- Multiple reticle options: Some red dots offer different reticle patterns (dots, circles, etc.), allowing you to choose the best option for your shooting style.
- Shake awake: Similar to motion-activated illumination, shake awake is an energy saving feature that activates the red dot sight when the rifle is moved.
