Im getting the parts together for my first AR build. I have most of the lower parts but the one thing I havent gotten yet is a buffer tube. I do have a mil-spec magpul stock, so I know ill need a mil-spec buffer. Are they just a pretty anonymous part where one brand fits all? No high low or middle range of quality?

There are a lot of mil-spec diameter tubes out there, usually 6065 aluminum.
Then there are the mil-spec buffer tubes which are 7075 aluminum. Finish can vary by company. It's up to you whether you want all mil-spec parts and the amount of money you want to spend. If you really want to splurge check out the PWS buffer tubes. |

Pws buffer tubes are a fancy looking waste of money.
A proper mil spec RE is made from hammer extruded 7075. The best options are LMT, BCM, Vltor, and Colt ($). My recommendation is LMT, if it is good enough for KAC to use it is good enough for me. Last time I checked they were in stock at boltcarrier.com |

PSA just had 7075 6pos mil-size sets with carbine buffer, spring, etc for 28$ course, you have to wait until your hair falls out before they ship chalk it up as a lesson learned.... Will this work? That looks like everything I need and im not in a rush for it. |

If that just the tube or does the spring and white "plug" piece come with it? It looks like its just the tube. Quoted:

That looks like everything I need and im not in a rush for it. Looks fine, the only difference between that and the "Premium" one they had is it's probably made of the "cheaper" 6061 aluminum and only has 5 positions instead of 6. |

If you don't want mil-spec, it's fine. Colt, Vltor, BCM, LMT, Spikes. Rinse. Repeat. |

buffer aseembly
$25 at primary arms. Fast shipping as well. I've always been impressed by them. I dare you to find a single person on these forums which had a 6061 buffer tube which broke in some way, and a 7075 would not have. The firearms world as a whole loves to make it seem like if you don't have the best of the best, it will fail, and you will die. Meanwhile all these top companies have ridiculous profit margins because they brand their items as best of the best and at a high price, because to the tiny consumers brain, spending more means higher quality. |

1-You probably won't die if you buy a 6061 buffer tube.
2-Yes there is a difference. 7075: Tensile Yield Strength 503 MPa 73000 psi AA; Typical 6061: Tensile Yield Strength 276 MPa 40000 psi AA; Typical ETA: If 6061 is adequate, why do so many companies who sell "Mil-Spec diameter" tubes hide the fact that they are 6061? |

Havent you ever taken a marketing class? ETA: with that said, find me the person where 6061 was proven inadequate. they could develop some sort of carbon nano-tube buffer tube for $100 and it still wouldn't be worth it because you will never even come close to using the potential of a 6061. Its like buying a $20,000 car which has a bumper to bumper warranty for 250k miles and no time limit.. then paying an additional $10,000 to extend the warranty to 400k. |

How many people would even know what there buffer tube is made from? What if you are building a rifle where your life might depend on your rifle, you run your rifle hard, or you want the very best ar15 parts out there, etc. TERRIBLE ANALOGY. Mil- Spec 7075 buffer tubes are $20-$30. You are paying more because 7075 costs more. Many 6061 mil spec tubes are about the same price or $5-10 less - at the most. Typically companies who have a mil-spec tube that is 6061 doesn't mention what it is made from. Sorry but I'm not trying to attack you or start a fight.. I'm sure your a good guy. And yes there probably isn't too much difference between the two tubes for the average AR owner. But I do think your analogy sucks...no offense. |
