This comprehensive bolt kit is specifically crafted for the iconic **Remington 700** and its variants, including the **Model 700, 700PSS, 700PSSA, and 700SPS**, as well as other chamberings that utilize the **12-point Derby action**, ensuring seamless integration with rifles chambered in **.308 Winchester, .30-06 Springfield, .270 Winchester, .243 Winchester, and other popular medium-power cartridges**. The kit is built to enhance the rifle s already legendary accuracy by refining the bolt s operation, reducing friction, and improving overall durability key factors for those who push their firearms to the limits in benchrest, long-range shooting, or tactical applications.

At the heart of this bolt kit is the **12-point Derby cover**, a meticulously machined component that replaces the stock bolt cover, offering a lighter, stronger, and more aerodynamically efficient design. The cover is crafted from **high-grade aluminum**, precision-milled to exacting tolerances to minimize weight while maintaining structural integrity, allowing for a more balanced rifle with reduced recoil and improved handling. The cover s sleek, streamlined profile not only enhances the rifle s appearance but also reduces air resistance, contributing to a more stable platform for precision shooting. The kit includes a **new bolt face**, which is polished to a mirror-like finish to ensure consistent chambering and extraction, reducing the risk of hang-ups or misfires critical for shooters who rely on their rifles for high-volume or rapid-fire scenarios.

Additionally, the kit includes **new extractor and firing pin assemblies**, which are precision-ground to ensure smooth operation and consistent extraction, even with older or less-than-perfect ammunition. The firing pin is designed with a **flat, hardened tip** to prevent premature ignition and ensure consistent primer strikes, a critical factor for accuracy and reliability in competitive shooting.

For shooters who prioritize **adjustability and customization**, the **Arlen Ness 300-938 kit** includes a **new bolt lift**, which is often a weak point in stock Remington 700 actions. The upgraded lift is machined from **high-strength steel** and is designed to reduce wear and prevent binding, ensuring that the bolt cycles smoothly even after extensive use. The kit also features **new bolt stop and sear components**, which are precision-machined to eliminate play and ensure a crisp, repeatable trigger pull essential for precision shooting. The **bolt stop** is designed to engage the bolt with minimal resistance, while the **sear** is tuned for optimal tension, allowing for a clean, predictable reset after each shot.

Beyond its performance benefits, the **Arlen Ness 300-938 bolt kit** is a testament to the brand s commitment to **durability and longevity**. Every component is manufactured from **high-grade materials**, including **chrome-moly steel for critical parts** and **anodized aluminum for lightweight components**, ensuring resistance to corrosion and wear even in harsh environments. The kit is **fully compatible** with aftermarket stocks, scopes, and other modifications, making it an ideal choice for shooters who are building or upgrading their rifles for maximum performance. Whether used in a **benchrest setup, a tactical rifle, or a long-range hunting rig**, this bolt kit delivers the precision, reliability, and refinement that serious shooters demand.

For those who take their shooting seriously, the **Arlen Ness 300-938 12-Point Derby Cover Bolt Kit** represents a **cost-effective yet high-performance upgrade** that can transform a stock Remington 700 into a **sub-MOA shooting machine**.

Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Arlen Ness 300-938 Derby Cover Bolt Kit**

1. **Enhanced Durability** The Derby cover is known for its high-quality leather, which is thicker and more resistant to wear compared to standard covers. This makes it ideal for players who field hard-hit balls frequently, such as catchers or first basemen.

2. **Improved Fit and Comfort** The bolt system allows for a more customized fit. Players can adjust the tension on the cover to ensure a snug, secure feel without sacrificing flexibility. This reduces slippage and improves control over the ball.

3. **Better Ball Protection** The reinforced leather helps absorb impact, reducing the risk of the glove s structure being damaged by frequent use. This is particularly useful for players who handle many hard throws or field line drives.

4. **Aesthetic Appeal** The Derby cover has a classic, professional look that many players prefer. It adds a premium feel to the glove, making it more visually appealing than standard covers.

5. **Compatibility with High-End Gloves** This bolt kit is designed to work seamlessly with top-tier gloves from brands like Wilson, Rawlings, and others. It s a straightforward upgrade without requiring major modifications to the glove s existing structure.

6. **Easy Installation** The bolt system is relatively simple to install, especially for those with basic tool knowledge. Arlen Ness provides clear instructions, and the process typically doesn t require professional help.

7. **Long-Term Value** While the upfront cost is higher than a standard cover, the extended lifespan of the glove justifies the investment. Players who use their gloves heavily will see a return on cost over time.

8. **Customization Options** Some users can further customize the fit by adjusting the bolts to their preference, whether they want a tighter or looser feel.

### **Cons of the Arlen Ness 300-938 Derby Cover Bolt Kit**

1. **Higher Cost** Compared to standard covers or even some other bolt kits, this kit is more expensive. The premium materials and craftsmanship contribute to the higher price point, which may not be justified for casual or infrequent users.

2. **Potential Overkill for Some Players** If a player doesn t field many hard-hit balls or doesn t prioritize durability, the benefits of the Derby cover may not be worth the extra cost. A standard cover or a mid-range bolt kit might suffice.

3. **Learning Curve for Installation** While the installation is manageable, it requires patience and attention to detail. Mistakes during installation (e.g., uneven tension or misalignment) can lead to a poor fit or premature wear.

4. **Weight Consideration** The Derby cover is heavier than standard covers, which could affect the glove s overall feel, especially for players who prefer a lighter glove for quick adjustments or throws.

5. **Maintenance Requirements** High-quality leather like Derby requires regular conditioning to maintain its supple texture and prevent cracking. Neglecting maintenance can reduce the cover s lifespan.

6. **Limited Color Options** Unlike some other covers, the Derby cover is primarily available in classic brown or black. Players who prefer vibrant or custom colors may find this limiting.

7. **Not Suitable for All Glove Types** While it works well with most high-end gloves, some older or non-standard models may not accommodate the bolt system properly. Always check compatibility before purchasing.

8. **Resale Value Impact** While the kit itself may not affect resale value, the fact that it s a bolt kit (rather than a standard cover) could deter buyers who prefer original or unmodified gloves.

### **Conclusion**

The **Arlen Ness 300-938 12-Point Derby Cover Bolt Kit** is a superior choice for serious players particularly catchers, first basemen, or anyone who prioritizes durability, fit, and performance. The investment pays off in the long run for those who use their gloves frequently and want a premium feel. However, for casual players, budget-conscious buyers, or those who don t need enhanced durability, the higher cost may not be justified.

The kit excels in durability, customization, and professional aesthetics but comes with a steeper price tag and requires careful installation. If you re committed to maximizing your glove s lifespan and performance, this is an excellent upgrade. For others, a more affordable bolt kit or standard cover might be a better fit.

### **Recommendation**

- You are a catcher, first baseman, or infielder who fields hard-hit balls regularly.

- You want a glove that lasts longer with minimal wear and tear.

- You prefer a customizable, high-quality fit that enhances control and comfort.

- You re willing to invest in a premium upgrade for your glove.

- You re a casual player or don t use your glove frequently.

- You re on a tight budget and can achieve similar results with a lower-cost bolt kit.

- You prefer lighter gloves or have specific color preferences not offered by the Derby cover.

- You re unsure about installing it yourself and don t want to risk damaging the glove.

For most serious players, the **Arlen Ness Derby Cover Bolt Kit is a worthwhile investment** that significantly improves both performance and longevity. Just ensure you follow the installation instructions carefully and maintain the leather properly to get the best results.
