Okay, finally decided to take the step. It'll take a month or so to get all the parts together, but I just ordered my lower. Realized I'm never going to get this damn thing done if I don't go ahead and, pardon the pun, pull the trigger. http://palmettostatearmory.com/index.php/firearms/receivers/psa-ar15-lower.html Looked just about everywhere for a Spikes, but no one seems to have one, and PSA seems to have a good rep, so I decided it would work. I'll keep a running tally on parts and tools, until I get it finished. Currently, counting S&H, I am at $89.95.
