a fucking bullet button

>custom copper AR

Patina

i still think it's stupid how there's ban on non-us firearms

i just want me some legit overseas guns

Nigger they made a skeletonized gun out of a shitty metal

and then rusted it

that isnt patina, its corrosion

bright fucking blue, copper oxide

It is. It’s a specific surface treatment

theres probably holes all the way through it under that toothepast

They use it in prop making

>when the art major gets into gunsmithing

hate to break it to you, but bluing is "rust"

@MAC21500 good point

it's more like targeted oxidation

which has both its pros and cons

shhh, use small words

it looks like an avant-garde museum piece

bluing is not 'rust'

It’s a a copper powder that is applied and selectively oxidized

what is rust bluing for $500

Rust is Fe2O3 you fucking retard

(The copper patina)

its red oxide, and it eats the metal

Blueing is entirely different chemically, and it is a desireable surface finish

Stubbs needs some educatin

^

dont talk shit to me about metallurgy you fucking brainlets

well

only iron can rust

iron is the *only* metal that can rust

oh shidd, we got some galaxy brains in here

The biggest of brains

the others 'oxidize'

A blued surface is Magnetite you fucking mongloid

is that a pokemon

jk

how dare you assume my race

Bluing is a passivation process that involves having at least two brain cells to rub together
