How many of you have contemplated building your own AR platform rifle?

For those of you who haven't built one yet, something to consider when working up the cost of the build...the tools needed to do it right. Factor those in. You may think to yourself "hey I can buy that XYZ plastic builders wrench." Yes you can, you will end up regretting it later. As my father told me years ago, "buy it once, cry once," still rings true today. That doesn't mean ambush the Snap On truck to get what you need, but quality tools, more so the right tools, can make your build easier, likewise using a cheap wrench and a multi tool may give you hours of headaches. If your not good with tools, then put it towards the rifle you want. Too many guys go cheap, get cheap and are not happy with it later.
