Great Match To My STAG ARMS Lower
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.

Solid and reliable
I've had this upper mated to a early production Stag lower (27xxx s/n) for over two years with more than 20k rds of steel and brass cased, 223 and 5.56, with over half being suppressed. I've punished this upper and have never had so much as a hiccup with it. Bottom line, I would trust my life with it.
