Q: What is the compatibility of this upper?
A: All of our complete uppers are compatible with mil-spec lower receivers.
I inherited a good AR-15 the had a "built" upper. I ordered the STAG ARMS M4 upper to replace the built one. Now I have a complete AR-15 M4. Both upper and lower are a great match. Fires well. I am very pleased with my traditional AR-15 M4.
As always fantastic quality and shoots like a dream.
