Titanium bolt carrier

[F22_RaptoR]

Why not go with a lmt semi auto carrier? It's lighter than the milspec fa carriers. And substantially cheaper than titanium. Which incidentally most tiatnium alloys performs poorly under friction loads.

This, or as already mentioned; the JP lightweight bolt carrier.

If you really want a super light upper/lower set, the Battle Arms Development upper/lower are billet milled 7075-T6, and are nice and light with cutouts everywhere. You could try and get IRG to get them for you.

As mentioned; a Titanium upper/lower set won't be lighter than Aluminum, but because it's much less wear resistant, will not last nearly as long as an Aluminum receiver set would. Surprisingly enough, 7075-T6 Aircraft grade Aluminum is probably one of the best materials you can use for an AR15 upper/lower.

OR, just stick with the standard Forged upper/lower, because they're likely the lightest possible set you can get. The original forgings were meant to be as lightweight and strong as possible.

hey guys i am looking to lighten up my ar and im hoping to change some parts out to titanium. Im looking for a titanium bolt carrier aswell as basically any other titanium ar parts that i can get. Does anyone know where to buy a titanium bolt carrier in canada or any titanium ar parts for that matter.

Bad idea.

What type of rifle are you trying to build? Saying the lightest possible doesn't give us much. CQB, precision, three gun, all purpose rifle? What do you plan on using it for?

An AR15 can easily weigh sub 6lbs without any fancy components. The fact that you're spending a grand on a barrel that isn't really any lighter than an all steel 16" lightweight profile tells me that perhaps you're going after a high end precision rig that doesn't weigh a ton like most of them.[/QUOTE

Correct I have multiple AR I want a high precision unit as light as possible. I would say money isn't of concern but 100k like mentioned previously is out of my realm

Thanks for all the info. I am Sorry I should have been more specific I don't have any off the rack ar. I have all of mine either built by a Smith or I have built.them myself. I Did not realize that titanium was poor with wear resistance that is excellent to know I will then stay away from titanium. Most of the AR 's I have are built on atrs uppers and lowers which are aluminum already. I am not really building this for a specific purpose just to see how light of a AR I can get.

"I want a high precision unit as light as possible."

"I am not really building this for a specific purpose just to see how light of a AR I can get."

I'm still not sure what you're trying to build. The barrel that you plan on using isn't any lighter than a steel one. I pretty much guaranty that you could have a steel one made that is lighter than a carbon fibre wrapped one.

"High precision" usually involves magnified optics, this will add significantly to the overall weight of the rifle.

Someone already mentioned BAD uppers and lowers, here's is a pic of their upcoming OIP rifle (ounces is pounds), sub 4lbs. Light enough for you?

I know nothing about light guns but aren't polymers suppose to be "lighter"
