I am building my first AR on a budget. This will be used as a range toy and if a SHTF scenario ever comes up. I already have a MOE PSA lower kit built on an Anderson lower. I plan on shooting about 50-100 rounds every month so I probably would never wear it out. I have selected two options that I like PSA 16" Mid-length Freedom Stainless MOE BLK - Without BCG or Charging Handle - 48199 or PSA 16" CHF 5.56 NATO Mid-length Premium MOE BLK Upper - without BCG or Charging Handle - 507440. I know the FN barrel is much better and would last forever but it isn't the best for accuracy. The stainless "SHOULD" give better accuracy but it won't last as long and isn't as good as a 410 SS. There isn't much more info on the SS kit but it usually runs $100 cheaper at $219. That saving would get me the BCG and have a functional rifle that much quicker. Any advice would be appreciated.
