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. |

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. |

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... |
