    I just purchased a used Bushmaster AR-15 and I'm having trouble figuring out what kind it is. I have checked several websites and it seems I might have a mix of different kinds. I'm a first time AR-15 buyer, any help would be much appreciated.

    Looks like a do it yourself build, it's definitely not all bushmaster. That isn't a bad thing though, It is possible that all the major parts are bushmaster with an aftermarket stock and quad rail.

    Pics of the markings on the barrel, the upper and the bolt carrier group could help determine the origin.

    the quad rail, front grip and stock are aftermarket parts. the make/model should be stamped on the side of the lower receiver same as the serial number.

    do you have an idea of the year?

    A2 type upper with fixed carry handle, and carbine length hand guards. Looks like the heavy barrel.

    The last stamped line on the receiver is the model number, something like XM15- ???. Somebody named Bubba changed out the original stock and hand guards
    .

    looks to be a Bushmaster with an aftermarket quad rail handguard and aftermarket stock. possibly a M4A2 Carbine.

    It has no M4 profile on the barrel. Probably the heavy barrel.

    Agreed with what's been said.

    You have to remember---AR's are the Lego of the gun world.
    Anybody with ANY mechanical ability, the capacity to follow
    simple instructions and a couple of cheap tools can make an
    AR anything they want. HUGE aftermarket in any parts you
    might desire, 15 seconds to swap to a different upper.

    I know a LOT of people with AR's, and I'll bet less than 5 of
    them are still exactly as they came from the manufacturer.

    Yep. Much of the AR's appeal and why it has become the hottest selling rifle in the country is because of its modular construction. They are just so easy to customize.

    Don't be concerned about identifying a specific model number because it's likely impossible to tell. However, try to get to know the parts.

    What kind of barrel does it have? That can tell you what kind of ammunition is appropriate and will work best.

    What kind of buffer tube does it have? That will tell you what kind of stocks can be put on it.

    Thanks for all the replies! I have done a lot more research now and many of your comments helped me narrow down what I have. My main concern is the carry handle. I would like to replace the upper so I can have a rail. I hear with the right tools it is easy, I'm just a little worried to give it a go.

    It would be much easier to buy a new barreled upper than swap out A2 to A4 receivers. You could sell the mixalot upper instead. And get the barrel/profile/gas length/twist you really want along with the A4 upper.

    And you'd know exactly what you have!
