The lower is beautiful. I have several and love the precision. The lower deserves a 5. However, Zev (maker) did not include an ambi bolt rod in the parts kit that comes with the lower. And they are making it a pain in the…to get. So lower 5 customer service 2

Excellent receivers. I’ve used three matched sets of the MEGA ARMS upper and lower receivers. Excellent fit and finish and well worth the funds. AR10 builds.
Q: Are these lower receivers compatible with Armalite AR-10 upper receivers and parts?

A: They are not. These are SR-25 pattern which while visually similar is not compatible with Armalite uppers. At this time we do not carry any Armalite compatible uppers, sorry.
