PDQ lever installation question

[DDadams]

Here's what the PDQ is for those unfamiliar,


My question is - if I have this done to a lower and just use aluminum black rather having the lower cerakoted after is there a high probability of rust happening starting in this area of the lower?

I know it would be highER chance but if I were to be rather rough on this gun and shoot in adverse conditions not babying it immediately after - am I dooming it to rust?

Aluminum doesnt rust.

Aluminum can't rust.

Fify
It can oxidize, or you can cause galvanic corrosion if you introduce the wrong dissimilar metal, but it can't/ will not rust.

I have a lower that has rust on it though?

At least it sure looks like rust.. that's why I even asked. I thought it couldn't but I'm 99% sure this lower I bought a long time ago has rust?

I'll upload a pic when I get home.

That just means its not an aluminum lower. see if a magnet sticks to it. If you see rust, I'd bet its not aluminum. Use the side of the magwell to make sure you dont feel the pull from steel guts.

And as MGD said, it can oxidize, but that tends to stay on the surface and isnt typically as catastrophic as rust. You should be fine if you cover the raw metal with some kind of coating. It doesnt have to be a proper coating so long as you keep it lubed and dont hang out around wetness.

More likely seeing rust from steel pins.
The lower itself is almost always aluminum or polymer, neither of which is susceptible to rust.
Steel pivot pins, springs, trigger parts...can all rust, leaving rust sitting on your lower, but the lower isn't rusting.

It's in the magwell - which is why I didn't see it when I bought it. It's a Noveske lower - so it's definitely aluminum.

sounds like rust rubbed off from USGI mags.

^This right here.
It will clean off, with enough effort.

I didn't even think about that.

I'll still post a pic when I get home so my confusion feels justified.

I really was confused because I could have swore that aluminum did not rust but when I saw that I couldn't figure it out and that's what made me second guess the PDQ lever on another lower before this one I want to put one in.

To get an ambi 308 lower it's either this or spend like $450 minimum and I'm not really feeling that option right now unless I find one on here.

All that's left is this little bit. Being stubborn.

But there was probably 6 or 7 times this amount.

I didn't realize it could have just rubbed off from metal mags.
