    First time ordering from B Kings. I ordered this kit after shopping around for lower build kits, they had the best price of any site I’ve found( about $40 cheaper than even PSA after shipping and taxes), and shipping was cheap and very fast arrived in 3 days after checkout!!! Kit was as expected, good quality mil spec trigger, sba3 brace fit the buffer tube nice and tight and the toolcraft bcg is perfect. Overall very impressed with B king and will def order again.
