    M4A1 is going to be select fire. I believe it has a 14.5in barrel. You can easily make a fake M4 with the exception it won't be select fire unless you have the means of going through the necessary processes to do so. You basically need either a 14.5in with a added muzzle brake for postban or flash hider for preban to make it the necessary 16in in length to avoid it becoming an SBR. Also the uppers have the M4 feed cuts. M4 handguards and if you want...a non collapasable pinned postban carbine stock or a collapsable preban carbine stock. Depending on the date of the lower's creation determines whether or not the rifle can be in preban or postban form.

    Thats most of it. Hopefully it makes sense to you :) Others will have plenty of info as well.

    Here's my AR-15 in M4 configuration (minus full-auto parts):

    Also, the M4 has a 14.5" barrel, ramp cuts in the chamber, and the "step down" for mounting a M203. There is also the following:

    M16A4 which is a flat top with a 20" barrel and the modular handguards.

    Also, AR-15s come in many configurations. You can go with the A1 style that has basically fixed sights and can have full auto in the M16 varient; this can be 16 or 20 inches.

    The A2 style has an A2 sight system that allows for windage and elevation adjustments. In the M16 varient, they went to 3-round burst instead of f/a fire. Also available in 16 or 20".

    Then, the A3. This is about the same as the above except this has the removable carry handle so you can mount optics. This is 3-round burst in M16 designation.

    Oh yea.. Heres mine.. [​IMG]

    Mine is a Rock River Arms upper with a 16in barrel and fake flash hider pressed over the end of the barrel which keeps it at 16in.

    Stripped pre-ban Olympic lower: $750
    DPMS parts kit: $55
    Pre-ban Bushmaster M4 upper: $500
    Bushmaster telestock: $100
    Knights RAS: $275
    Knights panel kit: $75
    Knights single point QD sling attachment: $20
    Knights Aimpoint mount: $110
    A.R.M.S. #40 BUIS: $99
    GG&G front and rear QD Sling Things: $80
    GG&G single point sling attachment: $25
    Hogue grip: $10
    Surefire M900A: $550
    Aimpoint CompML: $325

    Hot damn! Worse than I thought -- $2,974.00 (plus shipping charges on almost everything).

    I look at it this way: the stuff was bought piece by piece so it wasn't like I laid down $3k all in one pop. If someone had offered me a rifle just like mine for that price all at one time, I would have passed. However, that is what makes the AR great, you can build it as you go and swap parts here and there between other rifles. Hell, I have probably been through 5 or 6 lowers with 8/9 uppers. Now, I am down to two ARs...

    Its the preban lower and Surefire M900 that add so much of the cost to his rifle it looks like. It all does look very nice though :)
    Without the M900 and Preban lower you are looking at a little under 2k which is alot. I think I spent around $1600 on my setup.
