I have been kicking around the idea of building a 243 or 25 wssm AR. I don't reload (yet) but I am thinking that the 243 will be the one that most likely takes hold the best. This will probably be a scratch built setup w/ a budget of 1000-1200 I am looking for the best bang for the buck. Low weight in a very portable package. I am looking at the olympic arms upper at the moment but certainly open to other options. I would really like a 20" barrel and colapsible stock in a flat top configuration
which one 25 or 243 and why?
where to buy upper?
what trigger assembly and parts for lower?
What tools to do a nice clean build without maring the finish?
Good magazines for the WSSM ARs?
Does it matter if the lower is stamped 5.56 and that is not the cal it shoots? I assume that it doesn't at least outside of commi-fornia.. I have heard of lowers being marked "multi-caliber" but don't care to pay extra for a stamp if it doesn't matter.
