Any recommendations for buffer tubes?
The PWS EBT Mod 2 seems good to go. Expensive though. |
|
Several quality receiver extensions available.
Weapon role? Milspec sizing or commercial? Budget? |
|
So long as it's 7075 and mil-spec dimensions, I have no brand loyalty on receiver extensions.

It really does not matter who you get it from, if it is a .mil spec tube they all work the same way.

Colt/LMT/BCM/Spikes/ALG/Aero Precision off the top.
Colt/LMT are my preferred. You may like something different. Buy 7075 from a reputable company and you are gtg. Past that it's bells/whistles and finish to choose from. |

I'm in this camp. Toms tactical has 7075-t6 mil spec 6 position buffer tube kits for like $36, it's so budget friendly that I never run any 6061 buffer tubes except for a few rifle length buffer tubes View Quote |

I'm going to give the Magpul receiver extension a try when I can find one for sale.

ALG makes a good 7075 tube for a decent price.
Doesn't really matter much, though. Buy the cheapest 7075 tube from a known manufacturer you can find and it will work fine. |

I am ok with the Brownell’s house brand tube.
I have one in use, but not many rounds through the weapon. |

Bought a buffer tube made by POF. Has similar features to the PWS EBT Mod 2 at a lower price.

I have enjoyed the Vltor A5 tube. I run it in on a 14.5" build.
Yes, it takes a proprietary buffer but it really has made shooting a carbine more liken to shooting a rifle in terms of softness and recoil jolt. https://www.vltor.com/shop/ar/stocks/aebk-a5-vltor-a5-stock-combo-kit/ |

It won't matter to most people, but there's a difference between mil spec size and actual mil spec. IIRC, true spec tubes are extruded, with rolled threads for strength.

You do have to be careful, there are a lot of tubes on the market right now that were made in China and even if they say they are 7075, I am willing to bet the majority are actually 6061. I have run into a few of them over the last couple of years.

My Partner with his machine shop also has the ability to test different metal materials to see if he is getting what he orders for many critical jobs he does for government contracts, part of the contracts he signs, he has to be able to guarantee they are what they spec out.

This above, you would have to destroy a buffer tube to figure out if it were 6061 or 7075. View Quote Flame photometry or atomic absorption spectroscopy are closely related methods, but involve destructive testing. These methods are most commonly used in material composition testing. |

XRF (X-Ray Fluorescence) is non destructive but about $10k investment. Flame photometry or atomic absorption spectroscopy are closely related methods, but involve destructive testing.

But again, I never claimed it was non destructive... LOL |

I never said it was non destructive, where did you guys get the idea I did? virtually ever single piece of metal he tests is destroyed, including the buffer tubes we have tested.. 10K is nothing, he has several millions dollars of machines in his shop.
