Whether you’re aiming to upgrade a hunting rifle or optimize a precision shooting platform, mastering the art of bedding your rifle stock is a valuable skill that can make a noticeable difference in your firearm’s performance.

Preparing the Rifle and Stock for Bedding

Before applying any bedding compound, it is crucial to prepare both the rifle action and the stock thoroughly. Begin by carefully disassembling the rifle, removing the barreled action from the stock. Ensure that all screws, bedding areas, and surfaces are clean and free from oils, dirt, or old bedding material. Use a solvent such as acetone or denatured alcohol to wipe down metal and wood surfaces, which will ensure proper adhesion of the bedding compound.

Inspect the stock for any existing cracks or damage that could affect the bedding process. If necessary, perform repairs prior to bedding. Mask off areas of the stock that should not receive bedding compound, such as the exterior finish, recoil pad, or barrel channel, using painter’s tape or plastic film. This will prevent unwanted adhesion and facilitate cleanup.

Applying the Bedding Compound

When ready to apply the bedding compound, it is essential to work in a well-ventilated area and wear appropriate protective gloves. The two most common types of bedding compounds are epoxy-based and polyurethane-based, with epoxy being preferred due to its strength and durability. Mix the compound according to the manufacturer’s instructions, ensuring a uniform consistency.

Apply a thin, even coat of release agent (such as mold release wax or petroleum jelly) to all metal surfaces of the action that will contact the bedding compound. This prevents the bedding from permanently sticking to the metal parts, allowing for easier removal and maintenance.

To bed the stock:

  • Place a small amount of bedding compound into the action recess of the stock.
  • Carefully press the barreled action into the stock, ensuring proper alignment and seating.
  • Torque the action screws to the manufacturer’s recommended specifications, which compresses the bedding compound and ensures a tight fit.
  • Wipe away any excess compound that squeezes out using a clean cloth or paper towel.
  • Allow the bedding compound to cure fully, following the curing time specified by the manufacturer. This may range from several hours to overnight.

Fine-Tuning and Finishing the Bedding

After the bedding compound has cured, remove the action from the stock carefully. Inspect the bedding surface for any imperfections such as bubbles, voids, or rough spots. If necessary, sand these areas lightly with fine-grit sandpaper to achieve a smooth, even surface that maintains full contact with the action.

Pay special attention to the following areas:

  • Action screw holes: Ensure they remain clear and are not filled with bedding compound.
  • Barrel channel: Confirm the barrel is not contacting the stock, preventing unwanted pressure points.
  • Trigger guard and magazine well: Verify that these areas are free from bedding material to avoid interference.

Once satisfied with the bedding, reassemble the rifle and check for proper function. Test the fit by removing and reinstalling the action several times to ensure consistent bedding without movement or gaps.

Common Bedding Issues and Troubleshooting

Bedding a rifle stock can sometimes present challenges. Being aware of common issues will help prevent costly mistakes.

Issue Cause Solution
Bedding compound sticks to metal Inadequate or missing release agent Apply a generous layer of mold release or petroleum jelly on metal surfaces
Voids or bubbles in bedding Improper mixing or application technique Mix compound thoroughly and apply evenly; use slow and steady pressure when seating action
Action movement after bedding Incomplete curing or insufficient compound Allow full curing time; consider adding a second bedding layer if necessary
Squeezing out too much compound Excessive compound applied initially Use minimal compound; clean excess promptly during seating
Stock cracking during bedding Over-tightening action screws Torque screws to recommended specs; avoid overtightening

Acetone/Alcohol Cleaning surfaces before bedding Removes oils and contaminants

Preparing the Rifle and Work Area for Bedding

Proper preparation is critical to achieving a successful rifle stock bedding job. Begin by ensuring that the rifle is completely disassembled, with the barreled action removed from the stock. This separation allows for precise application of bedding material and prevents unintended adhesion of metal parts.

Create a clean, well-ventilated workspace with sufficient lighting. Use a flat, stable workbench covered with disposable or easily cleanable surfaces to catch excess epoxy and debris. Gather all necessary tools and materials beforehand, including:

  • Quality bedding epoxy resin and hardener
  • Release agent (such as mold release wax or petroleum jelly)
  • Cleaning solvents (denatured alcohol or acetone)
  • Mixing containers and stirring sticks
  • Sandpaper (various grits, typically 320 to 600 grit)
  • Masking tape or painter’s tape
  • Rubber gloves and protective eyewear
  • Clamps or action screws for securing the action during curing

Prior to bedding, thoroughly clean the interior of the stock and the metal contact surfaces on the action to remove oil, grease, and dirt. Use denatured alcohol or acetone applied with a lint-free cloth. Allow all components to dry completely to ensure proper adhesion.

Apply a generous coating of release agent to all metal parts that will contact the bedding compound. This prevents the epoxy from bonding permanently to the metal, facilitating later disassembly.

Applying Bedding Compound to the Rifle Stock

Bedding involves creating a custom-fitted epoxy layer between the rifle’s action and stock to enhance stability and accuracy. Follow these detailed steps to apply bedding compound correctly:

  • Mix the Epoxy: Combine the resin and hardener according to manufacturer instructions, mixing thoroughly to a uniform consistency. Avoid introducing air bubbles by stirring gently but completely.
  • Prepare the Stock: Mask off areas of the stock that should remain free of epoxy, such as the exterior surfaces and barrel channel, using painter’s tape.
  • Apply Release Agent: Reconfirm that all metal contact surfaces have a light but complete coating of release agent.
  • Apply Epoxy to Stock: Using a small applicator or brush, spread a thin, even layer of epoxy inside the action recesses of the stock. Ensure coverage of all contact points where the action will rest.
  • Apply Epoxy to Action: Lightly coat the metal surfaces of the action with epoxy as well, focusing on the areas that will contact the stock bedding.
  • Insert the Action: Carefully seat the action into the stock, ensuring proper alignment and fit. Use the rifle’s action screws to tighten the action down gradually, applying even pressure to press the epoxy into all contact surfaces.

Maintain steady pressure on the action while the epoxy cures. This can be accomplished by tightening the action screws to manufacturer torque specifications or using clamps designed for rifle stocks. Avoid over-tightening, which may cause uneven bedding or distortion.

Finishing and Refining the Bedding Job

After the epoxy has fully cured—typically 12 to 24 hours depending on the product and environmental conditions—begin the finishing process to ensure a smooth, functional bedding interface.

Step Purpose Recommended Tools
Remove Action Separate the barreled action from the stock without damaging the epoxy layer Action screws, gentle twisting motion
Inspect Bedding Check for voids, high spots, or uneven areas that may affect fit or function Visual inspection, feeler gauges
Sand High Spots Remove excess epoxy to achieve even contact and proper bedding thickness 320-600 grit sandpaper, sanding block
Clean Bedding Remove sanding dust and contaminants for smooth operation Lint-free cloth, denatured alcohol
Reassemble Rifle Ensure correct fit and function with the newly bedded stock Torque wrench for action screws

Perform incremental sanding followed by repeated test fits to achieve optimal bedding contact. Avoid excessive sanding that could compromise the structural integrity of the bedding. Proper bedding contact should result in a stable, vibration-dampening interface that enhances accuracy without binding or undue stress.
