Biggs's Review of CMMG, Inc M4 Forged Mil-Spec Upper Receiver

I ordered this and paired it to a PSA lower. The fit was great. The finish is a little more matte than the lower but only on really close inspection. No play between the upper and lower. Everything fit together well. I am very pleased with it and would definitely recommend it and purchase it again
