Flip up rear sights have become increasingly popular among firearm enthusiasts and professionals alike. Their compact design and ability to quickly transition between a low-profile carry position and a ready-to-shoot configuration make them a versatile choice for various applications. This in-depth guide will explore everything you need to know about flip up rear sights, from their mechanics and benefits to choosing the right sight for your firearm.
Understanding Flip Up Rear Sight Mechanics
Flip up rear sights, often paired with similarly designed front sights, are designed for easy deployment. The sight typically features a hinged mechanism that allows it to fold down flat against the firearm's slide or receiver when not in use. This low-profile design is ideal for concealed carry or situations where a low-profile sight is advantageous. When needed, the rear sight is simply flipped up into the shooting position, providing a clear and unobstructed sight picture.
Types of Flip Up Rear Sight Mechanisms
Several mechanisms are used in flip up rear sights:
- Lever-actuated: These sights utilize a small lever to quickly deploy and retract the sight. This is a common and reliable mechanism.
- Button-actuated: Some higher-end sights use a button mechanism for smoother and more controlled deployment.
- Spring-loaded: These sights use spring tension to keep the sight securely in both the up and down positions.
Advantages of Flip Up Rear Sights
The popularity of flip-up rear sights stems from their many benefits:
- Low Profile: When folded, they minimize snagging on clothing or gear, making them perfect for concealed carry.
- Rapid Deployment: The quick flip-up action allows for immediate target acquisition when needed.
- Improved Accuracy: A well-designed flip up rear sight provides a clear sight picture, enhancing accuracy compared to some fixed sights.
- Versatility: They can be used on various firearms, from handguns to rifles, making them an adaptable sight option.
- Durability: Many are constructed from robust materials like steel or aluminum, ensuring longevity even under rigorous use.
Choosing the Right Flip Up Rear Sight
Selecting the right flip up rear sight requires considering several factors:
- Firearm Type: The sight must be compatible with your firearm's mounting system (e.g., dovetail, Picatinny rail).
- Sight Radius: A longer sight radius (the distance between the front and rear sight) generally improves accuracy.
- Sight Picture: Consider the sight's design and how it affects your personal sight picture. U-notch, square notch, and ghost ring are common designs.
- Material: Durable materials like steel or aluminum are preferred for their robustness.
- Brightness: For low-light conditions, sights with tritium or fiber optic inserts are valuable.
- Adjustability: Windage and elevation adjustments allow for precise zeroing.
Case Study: Comparing Two Popular Brands
Let's compare two prominent brands: Troy Industries and Magpul. Both offer high-quality flip-up sights but cater to slightly different needs.
| Feature | Troy Industries | Magpul MBUS |
|---|---|---|
| Material | Steel, often with a durable finish | Polymer (MBUS Pro is steel) |
| Mechanism | Lever-actuated | Lever-actuated |
| Adjustability | Typically windage and elevation adjustable | Typically windage and elevation adjustable |
| Price Point | Generally higher | Generally lower |
| Durability | Excellent | Good, but polymer can be more susceptible to damage |
Installation and Maintenance
Installing flip up rear sights usually involves removing the existing sights and carefully mounting the new ones, ensuring proper alignment. Consult your firearm's manual and the sight's instructions for specific details. Regular cleaning and lubrication will maintain the sight's functionality and longevity.
Conclusion
Flip up rear sights offer a valuable upgrade for many firearms. Their compact design, quick deployment, and enhanced accuracy make them a popular choice for self-defense, competition, and tactical applications. By understanding the various types and considering your specific needs, you can choose the optimal flip up rear sight to enhance your shooting experience. Remember to always prioritize safety and follow proper firearm handling procedures.
