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, significantly improves rifle accuracy by creating a perfect, stress-free fit between the rifle's action and the stock, eliminating inconsistencies.

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

Key tools include a Miles Gilbert Bedrock kit, bedding tape, chisels, a specialized barrel bedding tool, hand screws, stock maker screws, modeling clay, release agent, and mixing supplies.

How do you ensure a barrel is free-floating after glass bedding?

Bedding tape is applied to the barrel during the process to create clearance. After curing, a dollar bill test is performed by sliding it between the barrel and stock; if it moves freely, the barrel is properly free-floated.

What is the recommended curing time for glass bedding compound?

The bedding compound should be allowed to cure for a full 24 hours after application before the rifle is disassembled for inspection and final cleanup. This ensures a stable and durable bond.
