Commemorative 2020 rifle Trumpisher.

Just starting work on my new Trumpisher. This rifle will utilize my last SA/Bula receiver. It will have a USGI SA bolt, trigger group, op rod and late USGI SA rear sights, an LRB/ Criterion 18.5 1/10 parked barrel, USMC unitized gas cylinder with LRB brake on the end. Stock will be SA Walnut presentation grade from Fred's.

Does that have an orange infill paint or coloring?

Color differences are strictly a function of laser manipulation. No paint involved.

That's really cool. I know from physics colors depend on light wavelengths. But I would not have realised it could be manipulated in an engraved surface like that to reflect regular household lighting in a certain way.

Science was invented to baffle, or so it would seem.

This is like the rainbow colored bands that you get on a motorcycle exhaust.

Hot steel forms oxide layers that are transparent. The thickness of the oxide layer depends on the temperature. When light hits it, it reflects off the top surface of the oxide, but some of it also passes through and reflects off the steel underneath. The two reflections of light, which has a certain wavelength, have therefore travelled slightly different distances, so the waves will be out of phase, and will interfere with each other. If the difference in pathlengths was 1/2 a wavelength, the two waves will cancel each other out. If the difference in path is 1 wavelength, they will reenforce each other.

so if you have a 250nm thick layer, the extra distance traveled is 500nm, so 500nm light (blue/green) will reenforce, all other colors will be out of phase and will cancel each other to some extend.

This is why soap bubbles have colors, because the bubble wall is that thick. Some insects have bright green or blue colors, also some irridescent bird feathers, because they have a thin layer of oil on the surface which causes interference coloring effects.

Anti-reflective coatings on lenses are the same thing, which is why sometimes binoculars and scopes have red or green lenses - because they have thin surface coatings. Also eyeglasses. Hold them low and look at the reflection of a light that is above you - if you have AR coating, you sell see green or blue reflections.

So when you laser mark, if you control the power setting of the laser very carefully, it will create various thickness of oxides. It's not easy to do, which is why you don't see it often.

That is the Best receiver. It's perfect; beautiful in fact. That rifle is going to be huge!

Are these oxides permanent or such that could be scrubbed/worn off with routine maintenance? Like rust (bad) or patina (good)

Love that the serial number ends with "45."

Bravo Sir, I wasn't sure what to expect.
That's a nice touch.

Never tried scrubbing, but as they are thin, and the color is thickness dependent, I expect that any abrasion will impact the color you see.

Click bait headline, but satisfying content

Had a junk race car done up in "Punisher" graphics, it looked good

Keep us posted on the progess

Are you going to have a faux selector switch with "single" and "Pelosi" settings?
