I suspenct he's writing about the full length receiver extension found on Colt MT6400C carbines. The stocks are pinned in the extended position. The internals of this tube are machined in such a way that the buffer hits a block or dead-end where a normal carbine receiver extension would end.
My understanding is you could slide the stock on the existing carbine/dead-end receiver extension and have the comfort and storage of the new stock. You would still be running the carbine H buffer and spring in the same mode as before.
My opinion is that if you are going to change receiver extensions, get a Sully fixed stock, unless you must have the A1 length. Or get a carbine extension and set an adjustable stock in place and pin it in the shorter length.
Stickman,
My experience level is with my compliant MP15OR rifle bought in the summer of 2008 in a ban state. Having to struggle with upgrades due to things about my gun that I wasn't aware were different from a typical M4 when I bought it, and 90% of these upgrade problems have been a result of the buffer tube. Rather then explain it here are some quick photo's illustrating my concerns:
This is my M4 stock on the tube. Notice the allen nut.
This is with the hex nut removed, and the stock "collapsed" all the way to the castle nut. Notice the buffer tube sticking out of the back?
This is a quick measurement of the tube installed. Notice that it is 9 7/16" long installed.
This is the view of the only hole milled into the tube. This hole is threaded to accept the allen nut.
I can tell you that this tube is also not milspec in it's diameter, and I know this because I purchased a Midwest Industries rear sling attachment to install on it, and the tube is too big to accept anything that has an internal diameter for a mil spec tube.
The buffer spring for my carbine is the length of a carbine spring. And the internal length of the tube is much much shorter then 9 7/16". I am assuming that it is the same length as the inside of a Carbine tube.
Do you now see my reluctance to purchase something to install on this tube?
There is no information with the rifle regarding what the specs of this tube are, and when you purchase something for a tube, all you ever get in a description of the product regarding install information are statements like "Fits A2 Tube". I was emailing back and forth with MidWest Industries a couple of months ago trying to answer my question, and to no avail.
So there you have it, that is what I am talking about, and what I am warning people about. I haven't gotten a straight answer out of any trained professionals regarding what this tube actually is, so therefore I have to make assumptions, and I think it is valid to warn people with similar set ups in ban states that this may not be as easy of an install for us, as it is for others.

Well, that clears that up...it ain't a Colt.Interesting way they did it and similar to what my MT6400C was like, with the stock extended and pinned in the long position.
I'm saying this nicely, so please don't take it the wrong way. Your knowledge base is lacking and you are misunderstanding things. The fixed stock that this thread is talking about uses an A1 receiver extension. You are warning people about a problem that does not exist, it flat out isn't there, it never was.
If you want to start a thread about your specific piece that doesn't work with other stocks, it wouldn't be a big deal, but to come into this one and talk the way you have been has done nothing but derail the thread.
I'm sorry your current receiver extension sucks, but that has nothing to do with the EFX-A1. If you want to use a stock like this, it uses a rifle extension.

And that is what I was asking. Thank you. I was also stating that it isn't an "easy install" for ban state owners, and will require the purchase of a new buffer tube. IE increasing the cost. Considering that ban state buyers are most likely the primary civilian market for this product, I think this is something that could be addressed for us ignorant end users.
Thanks Stick for clearing that up.
