Maritime Environment project

[Diamondback]

Interesting question and an interesting project... this should be of particular interest to anyone in a wet/maritime climate, particularly here in the "Liquid Sunshine" of the Northwest.

when I was in, I had an NCO that would hose down his rifle in CLP, let it sit for like a half hour, and then start working on getting it somewhat dry. Granted we where always in the arid desert, but this practice might help keep a gun from corroding no matter the componets?

For those that do live in a salty and wet places, which parts of the rifle do you see need the most attention?

Front sight base, flash hider, screw heads mainly.

Get it coated, be it Cerakote or Duracoat.

I have to agree with the folks that think this is all just way too much for what the "problem" is.

This thread reminds me, I remember seeing an Inconel 600 small parts kit a while back and wondered if it was a gimmick or if there was actually some validity to using Inconel in small parts.

I'm curious to hear what others with knowledge on the subject think.

I’ve been curious about corrosion resistant LPK’s, just for S&G. I’ve wondered a bit why the design calls for chrome silicon small springs instead of stainless, considering the action spring and mag spring is stainless. Unfortunately I know little about spring materials, and I’m not even 100% sure I’m correct about the small springs in the lower being CS.

Is Inconel 600 a good spring material? Is it really significantly more corrosion resistant, and is there a downside in useful life? There must be some reason its not in widespread use.

Anything that's just blued or not even coated at all. A drop of rain on blued steel on a warm humid day will rust in minutes.

I’ve done a small amount of research since I posted this, and my suspicion is that Inconel 600 is, indeed, a good spring material. It combines corrosion resistance with good strength and lifespan. I need more reading on this.

Whether or not it matters is up for debate. I’ll probably buy some of the Inconel 600 springs and try them out.

I thought I would post these pictures as an example of a weapon that has been re-finished to stand up to sweat or exposure to salt.

I just to apart my Colt 25 auto that I have been carrying since I was 21 years old. I am now 67.5 years old. I had this Colt Armoloyded, (Industrial Hard Chromed), when I bought it back in 1972. It is the same finish on my M1 Garand that I posted in this Thread. It has been through many inside pants holsters that were ruined by sweat. I think it has stood up well and I don't think it would look this good if I didn't have it hard chromed back in 1972.

Probably overthinking, just looking at improving what's out there, the Corps and Navy have a long supply/support chain behind them. We service our own weaponsz so part of my thought process is putting together the combination of parts to cut down on corrosion even more than what Uncle Scrooge required, and partly just to do it. The aftermarket has all the improved coatings and materials available on AR parts, so it doesn't seem unrealistic to assemble a better mousetrap.

Cera/Dura coat it, lube your BCG, close your dust cover and be done. Also, you probably shoudn't leave your rifle laying on the beach for days on end.
