Ultimate Guide to Rifle Bedding: Glass Bedding Kits & Accuracy Improvement

As a long-time shooter and outdoor enthusiast, I’ve spent years chasing accuracy. One of the most impactful upgrades you can make to any rifle, especially those with factory synthetic stocks, is a proper bedding job. Specifically, a glass bedding rifle setup. This isn’t just about aesthetics; it’s about fundamentally improving how your action interacts with the stock, leading to tighter groups and more consistent performance. Whether you're looking at a rifle bedding kit for a hunting rifle or a precision platform, understanding the process and choosing the right materials – like a glass bedding kit or a complete pillar bedding kit – is crucial. This guide will walk you through everything you need to know, from the benefits of bedding to choosing the right rifle bedding compound and even specific considerations for bedding a Remington 700.

Why Bed Your Rifle? Understanding the Benefits

Factory rifles, while often accurate enough for general purposes, rarely maximize their potential. The biggest culprit? Inconsistent contact between the action and the stock. Here’s why bedding matters:

• Improved Accuracy: Bedding eliminates voids and inconsistencies, creating a stable platform for the barrel and action. This reduces barrel vibration and harmonic distortion, leading to tighter groupings.
• Enhanced Consistency: Temperature changes cause synthetic stocks to expand and contract. Bedding minimizes the impact of these changes on the action’s position.
• Reduced Stress on the Action: Uneven pressure from the stock can warp the action over time. Bedding distributes pressure evenly, prolonging the life of your rifle.
• Better Heat Dissipation: A properly bedded action can transfer heat more efficiently to the stock, reducing mirage and maintaining accuracy during rapid fire.

Think of it like this: your rifle is a precision instrument. Bedding is like fine-tuning that instrument to its full potential. It’s a relatively inexpensive upgrade that can yield significant results.

Types of Rifle Bedding: Glass vs. Pillar

There are two primary approaches to rifle bedding: glass bedding and pillar bedding. Often, they’re used in combination.

Glass Bedding: The Foundation of Accuracy

Rifle glass bedding involves filling the voids between the action and the stock with a specialized epoxy compound – the rifle bedding compound. This creates a precise, custom-fit interface. A glass bedding kit typically includes the epoxy, release agents, mixing tools, and instructions. The process involves carefully preparing the action and stock, applying the release agent, mixing the epoxy, and then carefully positioning the action in the stock before the epoxy cures. It’s a bit messy, but achievable for the DIYer.

Pillar Bedding: Adding Strength and Stability

Pillar bedding kits involve installing pillars – typically made of aluminum or steel – into the stock to support the action’s mounting screws. This prevents the screws from loosening due to stock flex and provides a more stable foundation. Pillars are often used in conjunction with glass bedding. They’re particularly beneficial for rifles with heavy actions or those subjected to recoil. REI Expert Advice highlights the importance of pillar bedding for heavier rifles.

Choosing the Right Bedding Kit & Compound

Selecting the right rifle bedding kit or individual components is crucial. Here’s what to consider:

• Stock Material: Different bedding compounds are formulated for different stock materials. You’ll need a glass bedding kit for synthetic stock if your rifle has a polymer stock. Wood stocks require different formulations.
• Action Type: Some kits are specifically designed for certain actions, like bedding a Remington 700. These kits often include pre-cut pillars and custom-fit bedding blocks.
• Temperature Range: Consider the temperatures you’ll be shooting in. Some compounds are more resistant to temperature fluctuations than others.
• Cure Time: Bedding compounds have varying cure times. Choose a compound with a cure time that fits your schedule.
• Color: While not critical, bedding compound comes in various colors. Choose a color that complements your stock.

Popular brands include Devcon, Brownells, and Pillar Bedding. Read reviews and compare specifications before making a purchase. Brownells offers a wide selection of bedding products and helpful resources.

Step-by-Step: Bedding Your Rifle (Overview)

While a full, detailed bedding tutorial is beyond the scope of this article, here’s a general overview of the process:

1. Disassembly: Completely disassemble your rifle, removing the action from the stock.
2. Preparation: Thoroughly clean the action and the bedding surfaces of the stock.
3. Pillar Installation (if applicable): Install the pillars into the stock, ensuring they are level and securely fastened.
4. Release Agent: Apply a release agent to the action to prevent the bedding compound from bonding to it.
5. Mixing the Compound: Carefully mix the rifle bedding compound according to the manufacturer’s instructions. Accuracy is key!
6. Application: Apply the bedding compound to the bedding surfaces of the stock.
7. Action Placement: Carefully position the action into the stock, ensuring proper alignment.
8. Screw Installation: Install the action screws, tightening them to the manufacturer’s recommended torque.
9. Curing: Allow the bedding compound to cure completely, following the manufacturer’s instructions.
10. Clean Up: Remove any excess bedding compound and reassemble your rifle.

Important Note: Bedding is a precision process. If you’re not comfortable performing it yourself, it’s best to have it done by a qualified gunsmith. Incorrect bedding can actually decrease accuracy.

Bedding a Remington 700: Specific Considerations

The Remington 700 is one of the most popular rifle actions in the world, and there are numerous bedding solutions specifically designed for it. Because of its widespread use, finding a bedding Remington 700 kit is relatively easy. However, there are a few things to keep in mind:

• Recoil Lug: Ensure the bedding compound properly supports the recoil lug.
• Trigger Guard: Pay attention to the trigger guard area, ensuring it’s properly bedded to prevent flex.
• Bolt Stop Notch: The bolt stop notch needs to be properly relieved in the bedding compound to allow for smooth bolt operation.

Many rifle bedding kits designed for the Remington 700 include pre-cut pillars and bedding blocks that address these specific areas. MidwayUSA offers a variety of Remington 700 bedding options.

Maintaining Your Bedded Rifle

Once your rifle is bedded, proper maintenance is essential to preserve its accuracy.

• Avoid Extreme Temperatures: While bedding helps mitigate temperature effects, avoid exposing your rifle to extreme temperatures for extended periods.
• Proper Storage: Store your rifle in a case or gun rack to protect it from damage.
• Regular Inspection: Periodically inspect the bedding for cracks or damage.
• Action Screw Torque: Check the action screw torque periodically to ensure they haven’t loosened.

Final Thoughts on Glass Bedding Your Rifle

Investing in a glass bedding rifle setup, whether using a complete pillar bedding kit or a simple glass bedding kit, is one of the best things you can do to improve your rifle’s accuracy and consistency. While it requires some effort and attention to detail, the results are well worth it. Remember to choose the right rifle bedding compound for your stock material and action type, and don’t hesitate to seek professional help if you’re unsure about any part of the process. Happy shooting!
