This has been answered numerous times I am sure  but please forgive my ignorance. What is the benefit of a $70 tube kit over a $20 one. Is it the spring, the tube or the buffer or are they just the same since they are mil spec anyway ??  I know some will say brand X,Y or z but what is the real benefit of the more expensive one.

7075 aluminum alloy has almost twice the yield strength of 6061.  And more than likely a better spring.  And sometime the buffer will actually be aluminum instead of plastic etc etc.  Cheaper ones will work, but not battle ready.  I do not know your needs so I make no comment on what to buy.

Vltor A5 system is a mid length system. Id go that route if it was in the budget.

Just paper punching. Just see so many price points and wondered what the main difference was. Thanks

The Vltor A5 system uses a tube that is longer than the standard carbine tube. It also uses a longer buffer, and spring. The tube is a 7 or 6 position depending on which A5 tube you get.. It allows you to extend your stock out a little longer than the fixed rifle stock. It also helps dampen recoil / muzzle rise.

In this video he compares the 7&6 position A5 tube to a standard 6 position carbine tube.

The 6&7 A's look to have the same length when fully extended but the 7 position has the first hole closer to the threaded end. I run a regular Vltor Imod stock on a 7 position A5 tube and it only collapse down to position 2, which by the video would appear to be position 1 on the 6 position A5 tube.

Here is some more info about the A5 system.

Yea I am aware of all that, you used a term relating to gas system length that was very confusing.  I don't own the Vltor A5, I have read about it on a few sites.  I know the size, and know you can get like 5 different buffer weights with it, it has a rifle length spring, but I have never seen or heard of it called a midlength.  Maybe I am sheltered and if so cool.  I was just commenting that using the terms interchangebly is a bit confusing.  No crime, just curious.

Yea sorry I was just referring to the fact that is shorter than a rifle extension, but longer than a carbine extension.
