Like said before, Building is addictive, and upselling yourself, as " For blank more dollars, Free Shipping", next thing you know, your $ 100.00 order, morphs into $ 300.00! Between that and" Buy once, cry once" and telling rhe wife its an "investment", only works for the first 2 or 3 builds! If you can wait for black friday deals, its amazing how much more quality you can justify, for the budget price. BCM are my work horse uppers, and with competant milling, iVe turned out some nice work IMHO. Now 308 builds are different, as there isnt a milspec standard, thus causimg some minor fitment issues. My current build is Aero precision M5 upper, 80% Lower, Rock Creek 20" ultra match barrel, CMC 2 stage trigger, Supurlative Arms Adjustible gas block, Sprinco Orange spring, Griffin Arms , SOB buffer, Suppressor taper mount flash/comp, Lantec BCG, Spuhr mount, US Optics 3.2-17 B-17 scope, PRS Magpul stock, and although Only 12 round through, once getting on paper, and overgassing problem, last 7 rounds touching at 100Meters. Its what i feel a drug high would feel like!
