I'm on my second complete build, and unable to locate the typical DD buffer tube I have in my other ARs. I've heard good things about LMT buffer tubes, but can't find them in stock either.

Joebobs, who I typically go to for several AR parts online, currently has milspec buffer tubes available for $20 less than the seemingly unavailable DD or LMT buffer tubes I've used or been seeking out. They don't list who produces their buffer tubes, but I'm sure they're quality knowing how they operate.

I have been able to locate some Vltor milspec buffer tubes, but they're 5 position instead of 6.

The last tube I purchased was a UTG pro and it's machining and finish are the best of any tube I have ever seen.

No, stick with known quality.  That or end up like the guy a few months back with a broken ATI tube.

If it's a mil-spec tube that's 7075 aluminum I'm sure it would be good to go!

Stick with a quality tube.  There are plenty out there...

Commercial size tubes are a crap shoot... Pretty loose tolerances.

The only brand milspec tube I have heard of with consistent issues are ATI

Cheap tubes can be noisy.  Quality tubes are made of 7075 aluminum and are polished or coated on the inside,  which makes them quieter as the spring moves inside.

Huge differences between real Milspec and much of the aftermarket. Cheaper aluminum, rolled threads, extruded, all make for an inferior product.

I just got the PSA Premium stock kit on a daily deal for $40, normally $60.  It's milspec, 7075, and has the inner coating.  Should arrive today.

Go with the JoeBobs one,you will be fine. No need to spend twice the money or more on a buffer tube.

JoeBob - 6061 aluminum - $24.95

PSA - 7075 aluminum - $29.95

Winner winner chicken dinner.

The Vltor tubes are excellent.

You already know, buy once, cry once- that's why you prefer Daniel Defense.
Go with the 7075 and know you did the right thing, it is worth the difference.

It is not a buffer tube. It is a lower receiver extension.

Fwiw, I have a dsa mil spec tube that is too short for the BHO. I replaced it with a PSA and it works great

What you need to know:

Milspec is smaller than commercial. The commercial tubes were made thicker so they could use cheaper aluminum. Which is fine as long as you know that.

Where it gets tricky is buying a milspec sized tube, because they come in both types of aluminum. A mil sized tube does NOT always mean mil spec. Mil spec is the size AND it is made of 7075 aluminum. The cheaper aluminum is 6061. The cheap aluminum is HALF the strength of 7075. Its still tough and for range or hunting use would be fine. For a shtf or defense weapon buy a 7075 tube.

Also, if getting 6061, commercial is stronger because its thicker. A little. And you must match your stock to the buffer. So if you already have a stock, then your choice of tube size is already made.

I was able to track down an LMT receiver extension today and castle nut so I'm G2G.

Yes, and I DO NOT like...  Put one on a buddy's build and after about 100 rounds the bolt carrier locked up.  After getting it apart, I found there was a rubber buffer inside the stock (an intergral part of the PWS assy) that had come apart and jammed the whole tube up. Called PWS and they sent a new "improved" rubber buffer...but in the end I have no confidence in this tube.  Stick with Mil-Spec...

Does anyone else make a mil-spec tube in 7075 that has the extensions to support piston carrier tilt like the PWS does?
