Frequently Asked Questions

What is glass bedding for a rifle?

Glass bedding is a gunsmithing technique that uses a two-part epoxy to create a precise, stress-free fit between a rifle's action and its stock, significantly enhancing accuracy and consistency.

What tools are needed for glass bedding a rifle?

Essential tools include a wood chisel for stock preparation, a gun vise for stability, bedding tape, release agent, a small cup for mixing epoxy, and the bedding compound itself, such as the Miles Gilbert Bedrock Bedding Kit.

How long does glass bedding epoxy take to cure?

The Miles Gilbert Bedrock Bedding Compound, like most two-part epoxies used for rifle bedding, typically requires a 24-hour cure time before the rifle can be disassembled and finalized.

Why is glass bedding important for rifle accuracy?

Glass bedding eliminates inconsistencies and stresses caused by a poor fit between the action and stock. This solid foundation ensures that external pressures, like those from bipods or sling attachments, do not negatively impact the barrel's harmonics and thus, accuracy.
