Why is there a difference in carbine buffer tubes? i.e. different lenths...

You mean mil spec vs commercial length of the carbine buffer tubes?

Aren't mill spec a different diameter?

There's four position, then there's six position. Six position being naturally longer.

Then there's mil-spec dia and then there's civ dia. Civ dia being larger in dia.

How about a 5 position?

Vltor has a 5 pos

I can't find a good Milspec 6 position tube for sale to save my ass. Good luck or buy new.

LMT


I guess I should have specified a used 6 pos tube. I already have the end plates and buffers, I just need a used tube, spring and nut. Not too many used ones floating around.

I use both terms but tonight I'm lazy and it's faster to type buffer tube rather than receiver extension.

Damn, I can't believe I just typed all of that out.

I'm spent!

I wasn't aware that the number of positions determined the length of the receiver extension. (thanks for the reminder Forest)

For example an LMT 6 position is the same length as a VLTOR 5 position, LMT just milled in more "holes". I made myself a custom 9 position fooling around in class which is pretty easy to do if you have access to a mill.

Now why in the hell the commercials are longer? I have no idea; just because I guess.

How much longer are they?

I'll go take a picture
VLTOR (5 pos) - LMT (6 pos) - Commercial (6 pos) and SamColt Custom (9 pos)

VLTOR and LMT are the same length. The commercial is about 3/4" longer. Picture doesn't show that too well and it doesn't show the angled end to match the angle of the commercial buttstock.

Looking at the threads on the bottom one it looks like a commercial version. I haven't seen a mil-spec receiver extension without the rolled over threads before.

BUT - looking at the stocks there it certainly looks like an issue stock.
