Glass bedding a synthetic stock is a technique used to improve the accuracy and stability of firearms. It involves embedding the receiver or action of a firearm in a bedding compound, typically a type of epoxy resin, which hardens to create a solid, stable foundation. This process minimizes the movement of the receiver within the stock, reducing vibrations and improving shot-to-shot consistency. This guide will delve into the intricacies of glass bedding, focusing on synthetic stocks.
Why Glass Bed a Synthetic Stock?
Synthetic stocks, while durable and lightweight, can sometimes suffer from inconsistencies in their manufacturing. These inconsistencies can lead to variations in how the action fits within the stock, causing points of pressure and uneven stress. This can negatively impact accuracy, especially at longer ranges. Glass bedding addresses this issue by creating a perfect, consistent fit between the action and the stock.
- Improved Accuracy: By eliminating flex and movement, glass bedding significantly enhances shooting accuracy. The consistent interface prevents shifting during recoil, leading to more repeatable shot groups.
- Enhanced Stability: The rigid connection between the action and stock reduces vibrations, resulting in a more stable shooting platform. This is particularly beneficial for precision shooting disciplines.
- Consistent Point of Impact: Glass bedding helps maintain a consistent point of impact, reducing the need for repeated zeroing adjustments.
- Reduced Recoil: While not directly reducing the force of recoil, the improved stability can make recoil feel less harsh and more manageable.
The Glass Bedding Process for Synthetic Stocks
Glass bedding involves several key steps. While professional gunsmiths are best suited to this task, a determined DIY enthusiast can achieve good results with careful preparation and attention to detail. Always prioritize safety when working with firearms and chemical materials.
1. Preparation is Key
Before starting, thoroughly clean the firearm's receiver and the stock's bedding area. Remove any burrs, imperfections, or old bedding material. This ensures a clean, consistent bond with the epoxy.
- Cleaning: Use a solvent such as acetone to degrease the surfaces. Pay close attention to all contact points between the receiver and the stock.
- Inspection: Inspect the receiver and stock carefully for any imperfections that could compromise the bond. Any irregularities should be addressed prior to bedding.
- Masking: Carefully mask areas that should not be bedded using painter's tape and release agent. This prevents the epoxy from adhering where it's not wanted.
2. Choosing the Right Bedding Compound
Several epoxy-based bedding compounds are specifically designed for firearms. These vary in their viscosity, curing time, and color. Select a compound that's appropriate for your specific firearm and skill level.
- Viscosity: Thicker compounds are generally easier to work with for beginners, while thinner compounds provide better penetration into tight spaces.
- Curing Time: The curing time dictates how long you must wait before handling the firearm after bedding.
- Color: Some compounds are tinted to make them easier to see and ensure even coverage.
3. Applying the Bedding Compound
Carefully apply the bedding compound to the receiver and the bedding area of the stock. The technique may vary depending on the chosen compound and the type of bedding (full or pillar bedding). Full bedding covers the entire receiver, while pillar bedding uses pillars to support the action.
- Full Bedding: Requires precise application to ensure even pressure distribution and avoid trapped air bubbles.
- Pillar Bedding: Involves installing pillars in the stock before applying the compound, offering advantages in terms of action alignment and stress distribution.
This process may involve using a syringe or spatula to apply the epoxy. Always follow the manufacturer's instructions.
4. Curing and Finishing
Allow the bedding compound to cure completely according to the manufacturer's instructions. This typically takes several hours to a full day. After curing, remove any excess bedding compound and clean any residual material.
- Careful Removal: Use a sharp tool to remove excess epoxy. Avoid damaging the receiver or stock during this process.
- Final Cleaning: Clean any residual compound with appropriate solvents and fine sandpaper, ensuring a smooth surface.
- Inletting: If necessary, you might need to perform additional inletting to get a perfect fit after the glass bedding compound has cured.
Case Study: Enhancing the Accuracy of a Remington 700
A Remington 700, a popular bolt-action rifle, can benefit significantly from glass bedding. A case study showed that after glass bedding a Remington 700's synthetic stock, shot group sizes were reduced by an average of 40%. This dramatic improvement demonstrates the effectiveness of the process.
Conclusion: The Benefits of Glass Bedding a Synthetic Stock
Glass bedding a synthetic stock offers significant improvements in accuracy and stability. While requiring careful preparation and execution, the process is achievable for both professionals and skilled DIY enthusiasts. By carefully following the steps outlined above, and consulting relevant resources and professionals where necessary, you can enhance the performance and longevity of your firearm. Remember that safety should always be the top priority when working with firearms and chemicals. Proper safety precautions and attention to detail are critical for success in this undertaking.
