Frequently Asked Questions

What is the primary benefit of glass bedding a rifle stock?

Glass bedding a rifle stock, especially when combined with a free-floated barrel, is an excellent way to improve rifle accuracy. It ensures a perfect, stress-free fit between the rifle's action and the stock, which minimizes variables that can affect shot consistency.

What are the essential tools needed for glass bedding a rifle stock?

Key tools for glass bedding include a dedicated glass bedding kit like the Miles Gilbert Bedrock kit, bedding tape for barrel clearance, chisels for wood removal, a specialized barrel bedding tool, stock maker screws, modeling clay, and cotton swabs for applying release agent.

How do you ensure a rifle barrel is properly free-floated after glass bedding?

To ensure a barrel is free-floated, bedding tape is applied to the barrel during the bedding process to create clearance. After the compound cures, a dollar bill test is performed by sliding it between the barrel and stock; it should move freely along the entire length.

What is the cure time for glass bedding compound?

The Miles Gilbert Bedrock Glass Bedding Kit, like most two-part epoxy bedding compounds, requires a minimum of 24 hours to cure fully. It's crucial not to disturb the rifle during this period to allow for a strong, stable bond.
