    BTW: I love your signatures. Lol.
    I would not spray PB Blaster on a carbine I liked. Ever seen that stuff eat a styrofoam cup? I have to think it probably wouldn't be good for the polymer parts, not to mention it penetrates like crazy and would stand a decent chance of killing some of your ammo if it got on it. Keep penetrating oils away from ammunition!

    i've been using PB for gun stuff for a year and half, or so. it's been steadily becoming my main cleaner, and i've used it as a main ingredient for several home-brew CLPs and lubes- no problems with ammo nor plastics. i even have a small following of local guys who use my CLP... no complaints.

    If we're talking short term exposure to fresh water, I wouldn't be too concerned. I had an AR in the bottom of my boat (often partially submerged) every day for months in Alaska, didn't do anything special, and never had any problems. Allowing the bore to drain for a few seconds (as mentioned) if it's completely submerged is always a good idea.

    Get ready to laugh...
    Candle wax, Pledge and a condom.

    Use the candle wax over all joins and creases of the AR(where the upper/lower join, around the charging handle and around the dust cover). This should keep the internals protected. Spray Pledge over the entire rifle, it will leave a waxy film over all the metal parts to keep them from corroding. Rubber band a condom over the muzzle.

    That is how my cousin keeps his stored on his boat here in FL. Its a mess to clean the wax off and it will always start to smell like lemons when you shoot a couple of rounds and things start heating up. But, he has no rust anywhere on it.

    Just keep your go-to rifle inside a rifle case that floats, I keep mine in a bulldog rifle bag.

    Lube EVERYWHERE with Slip 2000 EWL.

    Buy a Fail Zero Bolt Carrier group (or Spike's Tactical; their Nickel-boron BCG's are coated by FZ).

    Own a 16" Mid-length rifle with a chrome-lined bore and chamber.

    Acquire a pelican or hardigg hard weapons case (they have waterproof models).

    I'm an LEO in FL and I deal with humidity every friggin day. I do everything but the case (saving up for it) and I have zero issues.

    If I might add my two cents. Di or gas operated , upon coming out of water I would pull the charging handle back a inch and that will allow the barrel and gas system to drain buy letting air in.
    If i knew the gun was going to be fully submerged I would lube with a product called "Marine Pal". The Seals use this product as it was designed for offshore oil drilling and doesn't wash off from water.
    The basic cleaning procedure after a mission in salt water is to totally flush the gun out with fresh water. Blow out with compressed air. do a regular gun cleaning procedure. and then relube with "Marine pal".

    You don't need a different gun for the use you describe. Maritime was a bad choice of words for your question.


    mar·i·time   /ˈmærɪˌtaɪm/ Show Spelled[mar-i-tahym] Show IPA
    –adjective
    1. connected with the sea in relation to navigation, shipping, etc.
    2. of or pertaining to the sea: maritime resources.
    3. bordering on the sea: maritime provinces.
    4. living near or in the sea: maritime plants.
    5. characteristic of a sailor; nautical: maritime clothing.

    Maritime use would be a few things.

    - How to keep my weapon operational after water exposure. (Corrosion resistance, rust, etc.)

    - Any method to make the weapon shootable after getting it un-submerged.

    Also another question:

    Would popping the rear pins and breaking the upper and lower real quick to let the water drain from the whole gun be the fastest way to get the water out?

    Would any barrel length or gas system be better? (Gas system being carbine, midlength, rifle, etc. Not gas piston, or DI.)

    Something tells me that an 11.5'' carbine might not be the best idea for this use.

    For this use the 12.7'' LWRCi might be the niche, and the KAC gets another duty.

    Would Slip 2000 be good lube for maritime use?
    If you live in an area prone to flooding, why wouldn't you need all of your carbines to be able to function properly in or around the water?
