Checked with Wilson Combat today on a complete 556 Wylde I've had on order since mid January. Told it will most likely one year before it ships due to a few parts but mainly the bolt carrier. I've also lack a bolt carrier for another build. Would take any 223 bolt carrier but prefer NP3 coating. Have not been able to find any bolt carriers. Seriously thinking of having a bolt carrier made at a local machine shop. Has anyone done this?
