    EDIT to add...

    This might be a fun experiment, I wonder if we should setup our own test and see what we get. Perhaps some uppers assembled and submerged in salt water for a set time?

    I could provide the parts to do so.

    I'm going to perform the test using a buffer tube and V7 Ti castle nuts. Sounds cheaper...

    Many gun parts are made from materials that corrode. If they are properly coated its not an issue, think anodized or parkerized.

    Raw titanium on raw aluminum is a bad idea. But what about DLC titanium on Anodized aluminum? and assembled with proper lube or loctite.

    That sounds good to me, so good in fact I'm giving it a shot.

    I am building on a 2A Armament balios lite receiver set, I have been using many V7 Ti parts. Barrel nut (milspec), gas block and muzzle device. All titanium parts are DLC and anodized aluminum. I used rock set or royal purple high temp lube.

    The final piece will be to replace the troy aluminum Mlok rail with the new;y released carbon fiber one.


    I am looking forward to seeing how the final product all works, I plan on running it through some VTAC classes and seeing how it all holds up.

    Mega and Hodge are doing that with the wedge lock barrel nut and rail. They seem like folks that would've tested it (especially since it's marketed as a hard use rail).

    This article might shed some light on the subject. It looks like raw titanium in contact with raw aluminum in a corrosive environment is a bad thing.

    Yea, for your average rifle, I don't think it's going to matter. Your not shooting over a tub of HCl.

    I think the reason we don't see much titanium on military adopted small arms is cost to benefit ratio.

    Military procurement always comes down to cost.

    Titanium is very expensive, it is hard to work. While lighter, the cost that comes at would never make it viable for a military small arm.

    But think where we do use it, Aerospace, we have put this stuff on the moon. Okay, I know the moon is not a corrosive environment.

    But what are the Russians up to with the stuff?, they love it and have lots of it. Well that make nuclear submarine hulls out of it, it must not do too bad in salt water...

    ETA: Military use of titanium in maritime environment. Russian Alpha class sub.

    Doesn't the M240L have a Ti receiver? How are those holding up?

    An M240 weighs 28 pounds empty, making parts of it out of titanium saves a lot of weight. Five and half pounds.

    A barrel nut weight next to nothing, making that out of titanium doesn't do much....

    That is true, even if you use all of the Ti parts available for an AR, the weight savings can't be more than four or five ounces. But Ti does have the "cool" factor that many find appealing, myself included.

    I think 4 or 5 ounces is a big deal.

    4 or 5 ounces on Ti parts+

    4 or 5 ounces on a barrel+

    4 or 5 ounces on a light weight rail+

    2 or 3 onces on a receiver set+

    3 or 4 onces on a light stock

    = All of the sudden you have lost and average of over a pound.
