Brownells Acraglas Bedding Kit

The Brownells Acraglas Bedding Kit is a rifle stock bedding compound designed to improve accuracy by creating a solid, stable interface between your rifle's barrel and action and its stock. Built on materials proven in aerospace applications, Acraglas has become the go-to choice for serious shooters—from competition teams winning regional and Perry matches to hunters looking to tighten groups on their hunting rifles. If you're ready to unlock hidden accuracy in a rifle that's been shooting okay but not great, this kit gives you the tools to do the job right.

What makes Acraglas stand out is its dimensional stability and durability. The compound shrinks less than one-tenth of one percent as it cures, which means the bedding you create today will still be there tomorrow. It's acid-proof, waterproof, and won't rot, deteriorate, or absorb moisture—critical properties when you're sealing the inletted side of a wooden or composite stock against gun oils, solvents, and humidity. The material also resists impact and won't dent under recoil, and if you ever need to adjust or repair the bedding, Acraglas makes that straightforward.

This kit includes everything needed to bed two rifles: resin, hardener, release agent, floc, mixing cups, a mixing stick, brown and black dyes for color matching, and detailed instructions. With a shelf life exceeding five years, you can stock this and reach for it whenever a project calls for precision bedding work.

Frequently Asked Questions

What can I use Acraglas for?

Acraglas is designed to bed rifle stocks—the process of filling the gap between the barrel/action and the stock interior to create a solid, stable platform. This improves accuracy by eliminating movement and inconsistency. It's used by competition shooters, gunsmiths, and hunters.

How many rifles can this kit bed?

This kit contains enough material to bed two rifles.

Will Acraglas damage my stock or finish?

The kit includes a release agent to help protect the stock and surrounding areas. Follow the included instructions carefully. Acraglas itself won't damage wood or composite stocks when applied properly.

How long does Acraglas last once cured?

Acraglas is highly durable and won't rot, deteriorate, or absorb moisture. It resists impact and maintains its properties indefinitely once fully cured, making it a permanent bedding solution.
