I was just wondering if the MP7 was fully submerged in the water and shot several times, would that damage anything?
If it /does/ damage something, are there replacement parts? (you probably know what im going to do with it!  :P

I'm guessing that the steel parts would rust.:gun:

I'd spray all the metal parts down with rust inhibitor before soaking it in water.

Boeshield T-9 and CorrosionX are known to be excellent performers.

ah, no... a lot of rust inhibitors are also not plastic safe.

Your gun should be fine, just dry off the outside, clear the bolt, and blow out the insides with some PC duster or compressed air to displace the water.

What do you mean by clear the bolt?

Sorry, this is going to be my first gbb, so

And if it DID rust, what are the effects the rust will have on the gun?

Can i get replacement parts for it?

EDIT: Ok, i just looked around in the pro shop and found out that MP7 parts aren't stocked.
So, Spiggy, how long can it be in contact with water until it will start to rust? Around last week, i left my toolbox outside whilst working on one of my boats. The wrenches were rust-free. It rained, and next morning, i found that my wrench was covered in rust.

Rust would compromise the integrity of the parts, small ones could break, the rust on the contact surfaces would flake, turn to dust and damage the trigger group, Ejaculate into the barrel and cause scraping, get into the gas system and potentially destroy o-rings, get into the magazine and cause marring along the length of it and damage bb's, and that sums it up. Rust = Bad. Playing airsoft in a swimming pool = Bad.

I did submerged it in water (actually a river) during an OPs once, as you can see in my AVATAR. No damages whatsoever after firing it but won't recommend it because you cant hit anything in excess of 8meters because your BB's will be flying around because of the water in the barrel and hop.

the accuracy would be sorted after its dried though, right?

Im not actually going to be flooding my mp7. For a long time i've wanted to play airsoft in the rain, so if it could survive being in a pool, then there's no doubt that rain wont be a problem.
I know there is a low chance of water actually getting in during the rain, i just want to be extra-safe.

Ah, yes...Boeshield T-9 is plastic safe.  I've contacted the manufacture myself.  If it can be used on commercial airplanes and high end bicycles, I'd trust it on my AEG and have.

Corrosion X is also plastic safe.  It can be used on electrical equipment and contact membranes, which are made of thin plastic...

Quote from Boeshield's web page:
* Lubricates and protects all metals for months.
* Will not harm paints, plastics, rubber or vinyl.
* Attacks existing corrosion.
* T-9® will also loosen rusted parts.
* Contains No Fluorocarbons.


Quote from CorrosionX:
Will CorrosionX harm paint, acrylic, plastic, etc.?
No. It will not stain or etch paint, nor will it harm plastic, acrylic or rubber.


Plus, I didn't say coat any plastic, I said wipe down metal parts.
Of course there are rust inhibitors that are not plastic safe, like WD-40.  This is why I recommended these two, Boeshield T-9 and CorrosionX.  

I wouldn't give out advice I didn't know anything about, don't have experience with, or can not back up.

If you are still uncomfortable with these products, coat everything in a light layer of silicone oil.  Although silicone is not the greatest rust inhibitor, it is better than nothing.

So i can spray my steel parts with CorrosionX to prevent them rusting?
I still do not know what parts are steel.

It would also be really helpful if you could help me with my M9, on the same topic.

Thread close.

Our products aren't design to use in water.
