    I’m good with my bcg, but I got to tell the crap I went thru to get it. The price was good , so i jumped on it. It was Shipped out in a couple of days, then It disappeared off the radar. I work for usps so l knew something was up. So I emailed b king about the package being possibly lost, to my surprise I got an email back with in an hour. For every email i sent i got a prompt email back. Finally by mutual agreement it was decided that it was indeed lost. B king gave me a refund and I reordered. I got the bcg in 4 days. This was for a .224 valkryie upper i was putting togethet. I wanted a good but inexpensive bcg, because i was building an ar15, no gas tube, side charge, single shot,upper ( I live in commiefornia, this is how I get around featureless). I needed to drill and tap the bolt carrier, so i didn’t want to spend big $ on a bcg.
    Thanks b king
