Q: What is the compatibility of this upper?
A: All of our complete uppers are compatible with mil-spec lower receivers.
Currently own a Stag arms lower receiver that I used with the bones upper. Functions great however the the fitment between the two isn't as tight as I thought it was going to be. Little loose compared to some others I own.
If it has to be left hand AR, it’s gotta be the original from Stage. Great product that’s reliable.
Great product...But it should come with a BCG. especially when you are ordering a left handed one.
