Ok, I ordered this kit http://dsgarms.com/ProductInfo/MGMOEKITOD.aspx and assumed I got a true mil spec 7075 buffer tube. In the description it doesn't state the type of aluminum but it does say mil spec not "mil spec diameter"

Now, the lower is already assembled and I just got word from DSG that the buffer tube is in fact 6061. What would you guys do?

My gut is telling me remove the tube and replace...thoughts?

My thought would be to not lose sleep over it but to each, his own.

What's the intended use of the gun?

Unless it's going to be some hard duty use, I pretty much echo Ryno's sentiment.

HD. I don't plan on throwing it off buildings; but I do prefer to do things the right way with the right parts.

I hear ya & I'm the same way but honestly, I doubt you can tell the difference between the two. If it bugs you & you can return it at no cost to you, have at it. Otherwise, I'd roll with it.

Then I would send it back and proceed with doing it your/the right way with this and not look back.

You don't want that nagging little voice going off your head, if you know what I mean.

I ordered that RE before I knew better. I'm still running it a few thousand rounds later but it's being replaced by an A5 kit. Never had any issues with it but I feel the same way you do OP, might as well do it right.

I say replace it, you'll have the confidence in it and if you ever have to strike something with the stock or be hard on it an any other ways you won't have to worry. It's not an expensive part but it's an important one.

What if you get, for example, a round stuck in the chamber and you have to mortar the rifle to clear it? I've had to do that on occasion to every one of my rifles (of course, I knowingly shoot some real crap surplus ammo). The buffer tube takes a pounding if and when that occurs.

That nagging voice is exactly why I went with an LMT tube on my "Now know better" rifle.

Get a better RE OP. Trust me.

I started a built were I only purchased what I considered the very best of each component, that way after I proof the rifle there will be no doubt in my mind that nothing was sub standard on my go to defensive long arm.

A few extra dollars equals peace of mind.

Per the TDP, the Receiver Extension must be made out of 7075 and hammer extruded. The inside is to have a dry film lube as well. From what I have seen only Colt, LMT, KAC and BCM follow this to the letter. There maybe others, but I don't know who they are.

I had a nagging voice in my head over this too, it went eventually being that I never noticed after a couple thousand rounds. Now its back again, though I am planning on switching to the A5 to see what it is all about.

How can the buffer tube fail if not 7075?

What about the VLTOR MilSpec Five Position Buffer Tube? (http://dsgarms.com/ProductInfo/VLRE-1.aspx)

DSG is out of stock for the LMT. If I hadn't already placed this order I'd be all over your Colt RE.

They used to have them made at a place that used the correct alum, but nothing else. I don't know if that is the case still (sorry).

Does anybody remember the stock failure test where they dropped a metal pipe with a RE and stock screwed on the end, weighting the equivalent of a loaded AR-15? Was it Weapon Evolution? They tested a dozen or so collapsible stocks.

They used 6061 RE's and they were pretty surprised at how well they took the abuse thrown at them.

EDIT: found it. It was the Military Times Gear Scout: http://blogs.militarytimes.com/gearscout/2012/02/01/buttstock-bashfest-gearscout-finds-out-just-how-far-tough-talk-goes/

7075 is about twice as strong as 6061

The biggest problem I've seen with REs claiming to be mil spec is interior finish. Like grant said, darn few have the dry lube, and some look like they had their interiors reamed with a handful of 8d nails glued to a dowel rod. I've never seen one fail, though, 6061, 7075, comm or mil, for whatever that's worth.

I'm pretty weary of the term "mil-spec" being thrown around in general. It's generally been abused beyond meaning. MIL-Spec? Really? So if some armorer wants to order by NSN, those parts are completely built to TDP, with all the appropriate QC, materials, processes, hardness, etc?
