Glass bedding is a popular technique among gun enthusiasts to enhance the accuracy and stability of their firearms. It involves filling the space between the gun stock and the receiver or action with a bedding compound, creating a solid, one-piece unit. This process eliminates inconsistencies in the stock's fit, preventing shifts and flex that can negatively impact shot placement. This guide provides a comprehensive overview of glass bedding, covering its benefits, the necessary materials, and a step-by-step process.
Why Glass Bed Your Gun Stock?
The primary benefit of glass bedding is enhanced accuracy. By eliminating the inconsistencies and potential movement between the stock and the action, you create a more rigid and stable platform. This leads to more consistent shot groupings and improved accuracy at longer ranges. Beyond accuracy, glass bedding offers:
- Improved Recoil Management: A solid bedding job reduces the transmission of recoil forces throughout the stock, resulting in a more comfortable shooting experience.
- Increased Durability: The bedding compound protects the receiver from damage caused by stock warping or movement.
- Reduced Vibration: By creating a more unified structure, glass bedding dampens vibrations, contributing to better shot placement.
Materials and Tools You'll Need
Before you begin, gather all necessary materials. Failure to have everything ready can compromise the bedding process. You'll need:
- Bedding Compound: Choose a high-quality epoxy-based bedding compound specifically designed for firearms. Several reputable brands offer excellent options. Research different formulations to find one suited to your needs and experience level.
- Acetone or Acetone-Based Cleaner: Crucial for cleaning and preparing the surfaces before applying the bedding compound. Ensure proper ventilation during use.
- Release Agent (Release Wax or Teflon Spray): Applied to areas you don't want the bedding compound to adhere to, like action screws and trigger group.
- Mixing Cups and Sticks: Disposable cups and stirring sticks are ideal for mixing the bedding compound accurately.
- Putty Knife or Spatula: To apply and spread the bedding compound evenly.
- Peel Ply: This thin plastic sheet is placed between the stock and the receiver/action to create the void that the bedding compound fills. You may need multiple sheets depending on the gun.
- Micro-balloons (Optional): For adding to the bedding compound to reduce viscosity and create a lighter mixture, particularly useful in filling larger gaps.
- Safety Glasses and Gloves: Protect your eyes and hands from chemicals and potential spills.
- Masking Tape: For protecting areas you don't want coated with the bedding compound.
- Compressed Air: For cleaning away excess dust and debris.
- Appropriate Work Area: A clean, well-lit area with adequate ventilation is essential.
Step-by-Step Glass Bedding Process
1. Preparation: Thoroughly clean the surfaces of the receiver and the stock where the bedding compound will be applied using acetone. This removes any oil, grease, or dirt that could prevent proper adhesion. Let the surfaces dry completely.
2. Masking: Apply masking tape to protect areas of the stock and receiver that you don’t want the bedding compound to adhere to. Be meticulous in your masking to avoid accidentally bedding unwanted areas.
3. Release Agent Application: Liberally apply the release agent to the action screws, trigger group, and any other areas that shouldn't be bedded. This ensures easy removal after the bedding compound has cured.
4. Peel Ply Placement: Carefully position the peel ply between the stock and the action, ensuring it covers the areas you intend to bed. This creates a clean, even layer that's easy to remove once the compound has cured.
5. Bedding Compound Mixing and Application: Follow the manufacturer's instructions precisely for mixing the bedding compound. Apply the compound evenly, filling the gaps created by the peel ply. Use your putty knife to work the compound smoothly into place.
6. Curing: Allow the bedding compound to cure completely, according to the manufacturer's instructions. This is crucial for achieving the desired strength and stability.
7. Peel Ply Removal: Once the compound has fully cured, carefully remove the peel ply.
8. Finishing Touches: Remove any excess bedding compound with a sharp tool and smooth the surface for a professional finish. Sanding and minor finishing work may be required.
9. Reassembly: Reassemble your firearm, ensuring proper torque on all action screws.
Safety Precautions
Always prioritize safety when working with chemicals and tools. Use appropriate safety gear, follow instructions carefully, and work in a well-ventilated area.
Conclusion
Glass bedding your gun stock is a rewarding process that can significantly enhance your firearm's performance. While it requires careful preparation and attention to detail, the improved accuracy and stability are well worth the effort. Remember that practice makes perfect; don't be discouraged if your first attempt isn't flawless. With experience, you'll refine your technique and achieve excellent results.
