    ok ok... so i got this DPMS lower right, and it has commercial buffer tube/stock. I was wondering if a mil spec buffer tube would fit onto my DPMS lower because i want to move onto the mil spec set up. I heard the difference between the two is 0.02". Is it going to be a real struggle screwing the mil spec tube into my lower receiver?

    All lowers are Milspec.
    Some come with commercial tubes.

    I'm sorry, if you read through the thread, it basically says that the buffer tube spec, is irrelevant. You can use either spec. Comm, or mil. It further goes on to describe that there may be differences, but not necessarily any advantage. Low price mil spec, is not as good as high priced comm spec, for example. What ever spec you use, you are going to get what you paid for.

    To answer your question directly, yes, you can use a mill spec stock on your DPMS lower.

    Is that better?

    The main difference on which buffer tube is important to you is the what type of stock you want to install. Some manufacturers only make Mil-spec stocks. I believe the LMT SOPMOD is one example.

    yip answered my question. I didnt know if my lower can accept a mil spec buffer tube. But from the infos given, all lowers are able to accept both comm and mil spec tube.

    Yes, it'll fit. And I'd go with a mil-spec buffer tube. It'll give you a wider range of stocks to choose from.
    Watch out for the rear takedown detent spring that'll pop out when you unscrew the tube

    My spring can't pop out. I tapped the hole for a 4/40 set screw, cut off the length of the set screw from the spring, inserted the detent & spring, and screwed in the set screw. Got the idea from this lower building guide
