History
The three-ounce bottle
Birchwood Casey makes no firearms or ammunition: it makes what is applied to them. The company dates from 1948 —“since 1948, serious shooters, collectors and professional gunsmiths have trusted Birchwood Casey” is literally all it says about itself— and now belongs to GSM Outdoors, the group named at the foot of every page in its catalogue. It is one of the group’s two brands that we distribute, alongside Walker’s.
Its name is attached to three products, the same three the brand names when introducing itself. Tru-Oil, a blend of linseed and other natural oils, restores the hand-rubbed finish of a stock without yellowing or cracking. Perma Blue, a liquid or paste cold blue, restores a rubbed area without stripping the firearm or putting it through a tank. Shoot·N·C targets reveal a green ring around each hit and save the walk downrange.
Around those three is a catalogue arranged by material. Metal: Perma Blue and Super Blue for steel, Aluminum Black for aluminium, Brass Black for brass and bronze, Plum Brown for browning a muzzleloader, plus the blue-and-rust remover and degreaser used beforehand. Wood: sealer and filler, walnut stain, Tru-Oil, wax and synthetic-stock rejuvenator. Cleaning and lubrication: Gun Scrubber, Bore Scrubber, black-powder solvent, Barricade rust protection, synthetic oil, RIG greases and biodegradable Renewalube. Targets: adhesive Target Spots, Shoot·N·C, Dirty Bird and Ground Strike polymer targets, which self-seal and withstand hundreds of shots.
Of the products that cross customs to reach Spain, two arrive with Spanish labels printed at the factory: the 3 fl oz liquid Perma Blue and Super Blue each have their own maker’s listing as Spanish, with a different reference from the standard version. The rest spans metal finishing, wood finishing, cleaning, targets and the firing point.
Product families
What we distribute
In the maker’s order: metal finish, wood finish, cleaning and lubrication, targets and firing point.
Metal finishing
Cold blue, browning and blackening, plus the remover and degreaser preparing the part. The catalogue’s oldest section.

Perma Blue
Cold blue for steel, available as liquid or paste. It produces an even blue-black finish without remaining tacky, and is used to restore a scratch or worn area without stripping the firearm. The 3 fl oz liquid bottle we distribute is the factory’s Spanish-label version, with its own reference.
Presentations


Presto Blue Mag
Liquid blue formulated for deep colour and a complete reblue rather than a touch-up. Not for stainless steel.
Format

Plum Brown
Barrel browning for the plum-brown finish of an original muzzleloader or replica, distinct from blueing.
Format

Aluminum Black
Blackener for aluminium parts, restoring scratches where steel blue has no effect.
Format

Brass Black
Blackener for brass, copper and bronze: furniture, butt plates and non-steel parts on old firearms.
Format

Blueing kits
A complete blueing job in one box, with everything required before and after: blueing solution, degreaser, blue-and-rust remover, applicators, sponge, cloth, fine steel wool and Barricade wipes. The Deluxe kit adds Tru-Oil, walnut stain and stock conditioner, so it also covers the wood.

Blue & Rust Remover
Removes old blue and rust to leave bare metal, the first step before reblueing and included in both kits.
Format

Cleaner-Degreaser
A liquid degreaser for metal surfaces. Any remaining oil creates an area that will not take colour, so without this preparation the blueing develops in patches.
Format

Presto Gun Blue pen
Instant steel black in a marker, for a rubbed trigger-guard edge or cover without opening a bottle.
Reference

Super Black pens
A black touch-up marker for painted or anodised surfaces, supplied in two finishes that must not be mixed: a gloss mark beside a matt surface stands out more than the scratch itself.
Finishes

Super Bright pens
Sight paint pens in white, red and green. Restore chipped or dull sights to a visible, non-permanent colour.

Sight Black
Aerosol leaving a velvety matt black on sights and metal, suppressing glare in the sight picture.
Format
Wood finishing
From bare stock to finished piece: sealer, stain, oil and wax. Tru-Oil is the company’s best-known product.


Kit Tru-Oil
A complete stock in one box: 3 fl oz Tru-Oil, walnut stain and stock conditioner, medium and coarse abrasive, fine steel wool, service and polishing cloths, plus guide. Applicator in reusable bag.
Reference

Gun Stock Sealer & Filler
Colourless sealer that blocks moisture and fills wood pores in one coat, before oil.
Format

Walnut stain
Water-based, true-colour, non-bleeding stain giving a clean deep colour without obscuring the grain. Fast drying.
Shades

Gun Stock Wax
Wax for a finished stock: protects and polishes and, unlike oil, is not removed by hand contact.
Format

Stock Rejuvenator
For non-wood stocks: restores faded synthetic colour and also shines plastic, leather and metal. Pump spray.
Format
Cleaning and lubrication
Bore and action solvents, rust protection, oils and greases. Half the catalogue and half of what we sell.

Gun Scrubber
Pressurised solvent that drives in, carries away dirt and dissolved residue, then evaporates without residue. Four cans from pocket to gunsmith size.
Formats

Aerosol firearm cleaner
High-pressure aerosol removing dirt, firing residue and oil without residue.
Format

Bore Scrubber 2-in-1
A bore solvent that attacks and dissolves every type of residue —lead, copper, plastic, carbon and powder— with one product. Available in a bottle, aerosol and foaming gel, the last of which remains inside the barrel instead of running out.

No. 77 Muzzle Magic
Water-based muzzleloader solvent removing corrosive black-powder residue and preventing rust. Flip cap.
Format

Brass case cleaner
Reloading-bench concentrate removing case lubricant, oil, dirt and tarnish from brass. A 16 fl oz bottle makes up to two gallons, without fumes or brass attack.
Format

Barricade
Long-term protection against rust: it displaces moisture from the pores of the metal and leaves a film that seals the surface. It comes in three application formats, including individual wipes for carrying in a gun case.

Hopper Spit
Metal protectant for harsh conditions and long storage. The maker reports outlasting competitors in salt-spray chamber tests.
Format

Synthetic Gun Oil
The company’s general-purpose oil: it reduces friction between contacting surfaces and protects the metal. Available as an aerosol for reaching the action, a spout can for controlled dosing, a pocket pump spray and a pen with two applicators.

Renewalube
USDA-certified plant-based biodegradable oil and grease. Displace moisture, prevent corrosion and lubricate, with a very high flash point.

RIG Universal Gun Grease
The company’s traditional storage grease for rifles, pistols, shotguns and muzzleloaders: a lubricant and preservative in one, applied before putting a firearm away for a season. Available in a gunsmith’s jar, a bench jar and a pocket tube.
Formats

SNO Universal Gun Grease
Grease for moving parts: reduces friction, semi-transparent, non-staining and polymer-safe.
Format

Choke Tube Lube
Grease for choke threads: prevents seizure, withstands barrel heat and protects against moisture, salt and rust.
Format

Moly Lube
A dry-film lubricant that leaves a smooth, low-friction surface on the metal instead of a layer of oil that traps dust. It is intended for the inside of the action.
Format

MLP lubricant pen
The dry-film lubricant in marker form, applying lubricant precisely to the component that requires it and nowhere else.
Reference

Cans used together: 1-2-3 contains 10 fl oz Bore Scrubber, Gun Scrubber and Barricade —dissolve, clean, protect—; the pair combines 10 fl oz Gun Scrubber with pocket synthetic oil.

Universal cleaning kit
Stainless rods and accessories for rifle, pistol and shotgun, with threads compatible with most market brushes, mops and tips.
Reference

Adhesive paper, reactive card and self-sealing polymer: see the hit from the firing point without walking downrange.

Target Spots
High-contrast adhesive aiming points giving a sharper sight picture and clean visible hole for group measurement. For rifle, shotgun, handgun and bow.

Shoot·N·C
A hit opens a lime-green ring around the hole, visible from the firing point without binoculars. Adhesive backing and repair patches extend target life.
Sizes

Dirty Bird
The non-adhesive version, printed on heavy card: each hit bursts bright white and can be identified at a distance. The targets work indoors or outdoors and can be hung anywhere.
Size

Ground Strike
Self-sealing polymer targets withstand hundreds of hits and retain shape. Spring models fall and return, the hanging one swings and balls roll. For .22 rimfire and above, not pellets or airsoft.
