    you need a barrel wrench and receiver block and a bench vise and torque wrench

    you can get barrel wrench and receiver block from brownells or midway or several other gun dealers do a seach for best price if you want to save a few bucks .

    torque wrench and vise can be bought at harbor freight and should also be at fred myers walmart bimart sears ect

    you will not need a head space guage (bullet looking thing) if you are using your original working mated bolt and barrel
    from your original working upper

    you will also need a small punch to knock out the gas tube pin i get those at sears but harbor freight has them as well and maybe some of those other places mentioned

    make sure you torque the barrel nut correctly

    Also check the Bushmaster site under parts. I just ordered from them. Got the barrel blocks, receiver blocks, and barrel wrench.

    If you don't want to buy the tools,i have everything needed on hand to do the job.
    Should you want to do the work yourself with some experienced guidance let me know,we could set up a time and it can be swapped over here.
