Is this 250g tin suitable if I am only bedding a single rifle stock at home?

No, the large 250g tin (SKU: ARMAPBN-250) is specifically sized for commercial gunsmiths and high-volume workshop use. For a single rifle bedding job, you should instead use the standard 50g tin (SKU: ARMAPBN) to avoid surplus waste.

Which epoxy base and stock colors are compatible with the Arma-Grout Brown Pigment?

This pigment is formulated specifically to tint Adhesive Engineering Arma-Grout 2-part epoxy rifle bedding compounds, such as the standard Arma-Grout Ivory kits. Adding the brown pigment tints the off-white resin to match wooden, walnut, or dark synthetic firearm stocks. For black composite or carbon fibre stocks, you should use the Black Pigment variant instead.

How should I mix the pigment into the epoxy without compromising the structural integrity of the bedding compound?

You should add the concentrated paste or powder pigment incrementally into the mixed resin and hardener until you achieve your desired timber shade. Be careful not to exceed recommended pigment thresholds, as using too much colorant can interfere with cross-linking, curing hardness, and the final recoil resistance of the bedding.

Does this chemical pigment require any special electrical compliance or regulatory certification for use in Australian workshops?

No, this product is a non-electrical chemical additive and does not contain any electronic components, meaning it does not require 240V power, an Australian plug, or SAA/RCM compliance marks. Adhesive Engineering manufactures Arma-Grout locally as an established Australian industry standard for firearm bedding systems.

Gunsmithing Brown Pigment - ARMAPBN-250

The Adhesive Engineering Arma-Grout Brown Pigment Large Tin 250g (SKU: ARMAPBN-250) is a concentrated colorant formulated specifically for two-part epoxy rifle bedding compounds, including Arma-Grout Ivory. Standard epoxy compounds cure to an off-white or ivory finish; incorporating this brown pigment alters the resin matrix to visually match walnut, timber, or dark synthetic firearm stocks. Engineered for rifle action bedding, recoil lug encapsulation, and support pillar installation, the formula disperses throughout resin and hardener components without compromising the chemical cross-linking, curing hardness, or structural integrity of the cured epoxy.

Key Features

Stock-Matching Aesthetic: Tints off-white epoxy rifle bedding compound to a consistent brown tone that blends with traditional timber and walnut stocks.
Epoxy-Safe Dispersion: Formulated to blend thoroughly into base resin and hardener mixtures without degrading cured bond strength or recoil resistance.
Concentrated Additive: Requires incremental additions to achieve desired shades, ensuring the total pigment volume remains well below the threshold that could affect epoxy cross-linking.
Workshop Packaging: Supplied in a large 250 g metal tin designed for repeated workshop applications.

Who is the Adhesive Engineering Arma-Grout Brown Pigment Large Tin 250g for?

Commercial Gunsmiths — Requires a bulk 250 g supply of rifle bedding epoxy pigment to consistently tint epoxy matrices across multiple walnut and timber rifle stock bedding jobs.
Armourers — Relies on a dedicated 250 g metal tin volume of brown colorant to maintain uniform timber-matching aesthetics across high-volume custom rifle builds and action bedding repairs.

Less suitable for: Single rifle bedding jobs where a standard 50 g tin provides sufficient pigment volume, or black composite and carbon fibre stocks that require a dedicated black epoxy pigment variant instead of brown.
