Stock Bedding Kits: Acraglas and Glass-Bed
Glass bedding a rifle stock creates a precise, consistent contact surface between the action and the wood or synthetic stock, eliminating the flex and inconsistency that hurt accuracy. Brownells Acraglas Gel and the Acraglas 2 Gun Accurizing Bedding Kit are the standard epoxy compounds gunsmiths use for this job — a slow-cure gel formula that fills gaps without running, and a kit that includes the release agent and tools needed for a clean job. The Glassbed Stock Bedding Kit and the 9-piece Glasbed Kit add the acraglas dye, application sticks, and mixing supplies for a complete one-project setup.
Formula 44/40 Gun Blue: Touch-Up Bluing
Formula 44/40 is a cold gun blue solution for touching up worn bluing on carbon steel — holster wear, small scratches, and thin spots on an otherwise sound blued finish. It's a cold-application chemical process, not a hot-tank rebluing, so it's suited to spot touch-ups rather than a full metal refinish. Clean and degrease the metal thoroughly before application for the finish to take evenly.
J-B Bore Compound: Copper Fouling Removal
J-B Bore Compound is a mild abrasive bore paste used to remove stubborn copper fouling that solvent-based cleaners can't fully break down, particularly in rifle barrels after heavy use. It's applied on a bore brush or patch and used sparingly, since it's a mechanical abrasive rather than a chemical solvent — most shooters follow it with a standard solvent pass to clear residue. It's a longtime standard in precision rifle maintenance for keeping a barrel's accuracy from degrading as copper builds up.
Gunsmithing Tools
The 1911 bushing wrench and AR-15 chamber brush are purpose-built tools for jobs that shouldn't be improvised. The bushing wrench allows correct removal and installation of a 1911's barrel bushing without marring the finish, and the chamber brush is sized specifically to clean an AR-15's chamber and locking lug recesses — areas a standard bore brush doesn't reach effectively.
Frequently Asked Questions
Does Impact Guns carry the full Brownells catalog?
No — Impact Guns carries a focused selection of Brownells gunsmithing consumables and tools, primarily stock bedding kits, bluing compound, bore cleaning chemicals, and a small set of specialty tools. For the complete Brownells parts and tools catalog, Brownells' own site remains the more comprehensive source.
What is glass bedding and do I need it?
Glass bedding fills the gap between a rifle's action and its stock with a hard epoxy compound, creating a more consistent, stress-free fit than wood or injection-molded stock ever achieves on its own. It's most valuable for precision and hunting rifles where accuracy matters and the factory stock fit is inconsistent — it's not necessary for general-purpose range rifles.
Can cold gun blue like Formula 44/40 fully reblue a firearm?
Not to the same standard as hot-tank bluing. Cold blue products are best for small touch-ups on worn spots on an otherwise sound blued finish, not a full strip-and-reblue job, which requires professional hot-bluing equipment.
