Glass bedding a synthetic stock is a popular technique among precision shooters and gunsmiths seeking to significantly improve the accuracy of their firearms. This process involves meticulously filling the void between the receiver and the stock with a bedding compound, creating a solid, one-piece structure that eliminates flex and point of impact shift. While seemingly straightforward, glass bedding requires patience, precision, and a thorough understanding of the process. This comprehensive guide will walk you through each step, equipping you with the knowledge to successfully bed your synthetic stock.
Understanding the Benefits of Glass Bedding
Synthetic stocks, while durable and lightweight, often possess inherent weaknesses that compromise accuracy. The inherent flexibility of the material, along with manufacturing tolerances, can lead to inconsistencies in the firearm's point of impact under different conditions or with varying ammunition. Glass bedding addresses these issues by:
- Eliminating Stock Flex: The bedding compound creates a rigid connection between the receiver and the stock, minimizing flex during recoil. This results in a more consistent point of impact.
- Improving Accuracy: By eliminating flex and ensuring a uniform bearing surface, glass bedding can dramatically enhance the accuracy of your rifle or shotgun.
- Reducing Recoil: The solid interface helps to absorb recoil more effectively, contributing to a smoother shooting experience.
- Correcting Stock Problems: Glass bedding can help compensate for minor stock imperfections or misalignments.
Essential Tools and Materials for Glass Bedding
Before embarking on this project, gather all the necessary tools and materials. Improper tools can lead to a messy and unsuccessful bedding job. Essential items include:
- Acetone or Methyl Ethyl Ketone (MEK): For cleaning the stock and receiver. MEK is more effective but also more aggressive.
- Glass Bedding Compound: Choose a high-quality compound suitable for firearm stocks. Follow the manufacturer's instructions carefully.
- Release Agent (e.g., PVA Release Agent): Prevents the bedding compound from adhering to areas where it shouldn't.
- Mixing Sticks and Containers: Use disposable items for mixing the bedding compound.
- Putty Knife or Plastic Spatula: For applying the bedding compound.
- Mixing Cups and Sticks: For measuring and properly mixing the bedding compound.
- Safety Glasses and Gloves: Always prioritize safety.
- Fine-grit sandpaper: For smoothing and finishing the bedding job.
- Cleaning patches and solvent: For cleaning the firearm after the bedding process.
- Clamps: Secure the rifle during the curing process. Use sufficient clamps to ensure a proper fit.
- Mask and Respirator: Protect your lungs from fumes.
Step-by-Step Guide to Glass Bedding a Synthetic Stock
1. Preparation: Thoroughly clean the mating surfaces of the receiver and the stock with acetone or MEK. Remove any dirt, oil, or grease. Pay close attention to details!
2. Applying the Release Agent: Liberally apply a release agent to all areas of the stock that should not be bedded. This includes action screws and any areas you wish to remain free for disassembly.
3. Mixing the Bedding Compound: Carefully follow the manufacturer's instructions for mixing the bedding compound. Ensure a consistent and smooth mixture to avoid inconsistencies in the final bed.
4. Applying the Bedding Compound: Apply the bedding compound to the receiver and carefully place the receiver into the stock. Use enough compound to completely fill all voids, but avoid excess material.
5. Clamping and Curing: Securely clamp the action in the stock, ensuring proper alignment. Allow the bedding compound to cure completely according to the manufacturer's instructions. This usually takes several hours or overnight.
6. Finishing: Once cured, carefully remove the clamps and excess bedding compound using a sharp putty knife or plastic spatula. Smooth any rough edges with fine-grit sandpaper. Clean any residue left behind with appropriate solvents.
7. Final Inspection: Inspect the bedding job for any imperfections and address them as needed. Ensure the action fits smoothly and that all action screws function correctly.
Important Considerations
- Practice: Consider practicing on a less valuable stock before tackling a prized firearm.
- Manufacturer's Instructions: Always strictly adhere to the manufacturer's instructions for both the bedding compound and the firearm.
- Patience: Glass bedding requires patience and attention to detail. Rushing the process can lead to errors.
- Professional Assistance: If you're unsure about any aspect of the process, consider seeking professional assistance from a qualified gunsmith.
By carefully following these steps, you can effectively glass bed your synthetic stock and significantly improve the accuracy and performance of your firearm. Remember, safety and precision are paramount throughout the entire process. This guide serves as a helpful resource, but always consult professional gunsmithing resources for advanced techniques or specific concerns regarding your firearm.
