Re: How easy is it to build an AR15?
My 13 year old son and I put one together recently. I purchased all the stuff locally, TNW stripped lower, DPMS lower parts kit, Tapco collapsable stock, and a DS Arms complete upper. I have somewhere north of $650 (probably closer to $700) into it, plus a few tools I bought. Other than the pivot pin (the one that could launch the spring into oblivion), my son did all the work on the lower.
My intent was not to build a 300 yard tack driver, but to assemble a rifle with my son and take him out shooting. Mission accomplished. The only downside is, I may have to build another one so I have one to shoot.
Here is a photo of him shooting it yesterday.
