So apparently you can't buy a stainless buffer tube for an AR? I guess people are too worried about weight? Still it would look great on the gun.
I guess you have to make your own.

3 positions for the stock. Screw heads retain the stock.

I made a design improvement so no threads show when installed. The stock does not collapse as much as the original but that was my choice.
If these are commercially available please give me the link!

Cool machine work but I'll stick with aluminum. You could always just bead blast aluminum and clear coat it if you wanted a silver look. And then there is Cerakote. I doubt anyone makes one because no one wants one. Good work though, enjoy it.

Clearly the photos above illustrate the incorrectness of that statement.

(i also realize you meant a large group of folks, just had to throw that out there)

may not be everyone's thing, but what good is it having the stock and the lathe without doing anything with it?  

Nice work OP.

Looks heavy, I could see using it on a .50 upper where the weight can be beneficial.

Wut?  

At this point you could make a key-mod dildo or put rails on a pistol grip and it will sell...

There is a buyer for every product.

V7 Weapons makes a Heavy Buffer tube out of 4140 steel that weighs 9.6oz.

Some guys want the old S/S lowers to come back for the extra weight also.

OP how did you attach the end-cap to the tube?

Some prairie dog guys I know out in SD have AR's and bolt rigs, the lightest of which is 14 pounds.  Having a gun that doesn't move allows one to see impact through the scope......and with prairie dogs and light bullets that move *REALLY* fast, that can be hilariously fun to watch.

The tube is about 1/2" longer than stock. The end cap is flanged and goes inside the buffer tube by 1/2" so the spring compression does not change. The machine screw at the rear goes through the stainless tubing wall and into a threaded hole in the end cap. It holds both the end cap and the rear of the bar in place.
How did you know about my next project with the rails on the pistol grip???

Anything stupid enough to think up, is stupid enough to try.

I think someone already did (read: put into production) the rail on a grip thing to attach a light.

I give kudos to anybody who can make anything themselves. Sometime it as much fun to make the parts with the knowledge you will have something no one else can have. Looks great having a mix of black and silver parts. I try to make my unfinished parts from titanium whenever possible even thought I know they will weight slightly more than aluminum. I just make them thinner or lighter in some other way since titanium is much stronger than aluminum.

I was just hunting google for a stainless buffer tube, so don't say no one wants one, but your right, this s the only one I could find

props

I have a lathe, but geez, not sure if I wanna do that much work, especially for a pistol tube

let me know when your ready to sell one

ARRobert:  Very nice work.  I like it.  What's the wall thickness back where the screws are located?

I think I'll put one of these on my 1lb 5oz welded steel lower.  Perhaps the new goal is not a complete rifle less than 6lb but one heaver than 15lbs.  LOL!!

I think it looks good. If a reputable company sold "in the white" 7075-T6 mil spec diameter receiver extensions I'd buy some.

If one wants a shiny look but doesn't want the weight of stainless steel. I came across a NiB Coated Buffer Tube.

The wall thickness of my SS buffer tube is about 0.085". I will weigh it next time it is off the gun. This is a target rifle only so I am not worried about the added mass.
I like the NiB coated idea. (Now you tell me.)

.085 is not too much thread engagement.  Are the screws holding the detent bar staying in place OK without stripping?  Perhaps you could have the bar TIG welded on.  A good welder can make some really small fillets on SS.  Just welding the ends of the detent bar to the tube would be adequate strength-wise and would not interfere with the stock movement along the bar.

Again, nice work.

Thank you for the compliment. My original plan was to TIG the front end of this bar in place. Most of the recoil can be carried by the rear screw which goes well into the aluminum plug. I realized that I needed the machine screw head up front to limit the stock travel so I decided to drill and tap it. So far it has held nicely. Now that you mention it, it deserves some red Locktite! If it ever comes loose I will TIG it in place.
