    Titanium M4 Parts

    Any manufacturers fabricating or machining titanium replacement parts aside from firing pins?

    I recall seeing an upper lower combo but it was something like $8000 or $13000. Or something along those lines. Some gigantic amount of money. Looking for a few minutes, and I can't dig it up

    I know you can get bolts and carriers with a titanium alloy finish, and firing pins made out of titanium... GAU-8 barrels have a titanium alloy applied to them.

    You're talking serious money here. What parts in particular do you want to be titanium? Your cost-benefit ratio is going to be very skewed in the direction of lots of money for little benefit.

    Titanium is a very difficult metal to work with.

    Remember, Titanium is lighter than steel and stronger than Aluminum.

    It is also heavier than Aluminum and weaker than Steel so there is not a lot it brings to the table for an AR.

    I would argue the Titanium Firing Pins on an AR are a downgrade as they are weaker.

    Ti makes good firing pins. It is more flexable than steel and should last longer and reduce lock time due to being lighter. Some alloys of Ti are as strong as steel and 45% lighter.

    Low grade Ti which is what most consumer aftermarket parts are made out of is weaker than 7075 aluminum

    Anyone wanting Ti for this kind of stuff is a loser.

    At this point I'd just be happy knowing what he's thinking.

    More aftermarket gadgets/widgets to separate the uninformed from their money.

    The AR is not a striker-fired weapon. 85% of your lock-time is in the arc of trave of the hammer.

    A titanium AR firing pin will give you a weaker pin for mabey a couple percent reduction in lock-time.
