    Can I interchange different stocks on the same tube? Assuming a commercial stock goes on a commercial tube and vice versa for Military spec.

    They're are either milspec or they're not. AFAIK there is no secondary "commercial" standard that non-milspec tubes will adhere to. In other words I don't think that there should be any expectation that non-milspec stock from Company A will fit a non-milspec tube from Company B.

    mil-spec have looser tolerances to allow for dust/sand

    There are two sizes of buffer tubes for stocks. Mil-spec and non-mil spec. If you're replacing a stock, you need to replace with the proper ones. If a stock is non mil spec, it will fit a non mil spec buffer tube, it is standardized.

    Mil spec is a smaller diameter, therefore a mil spec stock will not fit a non mil spec tube and a non mil spec stock will be too loose on a mil spec buffer.

    Most are non mil spec, RRA, Bushy and most of the other popular ones are non mil spec. Colt and a few other use the mil spec buffer.

    More detailed question. I have a CAA Stock that had a non mil spec tube included with it. Can I remove the stock and keep the tube and instead put say a Mag Pul stock on the CAA tube? Will it fit or is it like a 50/50 chance?

    You can keep the buffer tube and put the Magpul stock on it IF you get the non mil spec stock.

    If you're talking about the CTR stock, they make versions to fit both tubes, so just get the correct one.

    Far as I know, there are two buffer tube flavors - mil-spec and "commercial."

    The commercial tube seems to be a universal standard and has a greater outside diameter.

    Conventional wisdom is to get a mil-spec buffer tube and be done with it. I believe that the commercial tube is fading from the market (I want to say that RRA is switching to mil-spec, as well as a few others).

    it really doesnt matter either way. Just get a tube that matches the stock. Your commercial CAA (im 96% sure) will fit the other commercial diamter buffer.
    Theres no detriment to have the commercial, except you're not a cool as someone with a mil buffer.

    mil-spec tubes leave more room for the stock, this allows for sand/grit/etc

    pick up a les baer 1911 and compare it to a springfield "milspec" 1911 and you will bitch about the loose tolerances in comparison

    you guys pick up an ar-15 and you want military shit written all over it

    If you ever noticed a difference I'd be amazed, we're talking about thousands of an inch if I remember right. Get a stock to fit the tube you have.

    I don't plan on roaming the desert for five years so a commercial stock will work and even if I did a commercial stock would still do the job. :)

    Thnx for the help I plan on getting a CTR Stock to replace mine. ;)

    It's a rare aftermarket stock that fits commercial tubes unless it's a cheap basic collapsible stock just like the ones the manufacturers equip their rifles with.
