BCM upper assembly with laser T-markings has excellent fit and finish. T markings are laser etched clean and consistent. Forging shows BCM quality. M4 feed ramps cut correctly. Standard mil-spec dimensions throughout.
anodizing has a slight variation from the other receivers in my build but quality is there
BCM upper assembly with laser T markings drops in cleanly with any quality lower. Forging is reinforced around the pin lugs. M4 feed ramps cut correctly. Laser T markings are crisp on the receiver. Solid duty-style upper.
BCM upper assembly with the laser T markings is what you want for a duty style build. The T markings are laser etched not stamped which keeps the surface flat. Forging is clean. Standard mil spec dimensions, accepted my BCM BCG without any fitting.
BCM upper with laser etched T marks, alignment of the marks is precise. mated to a BCM lower with the takedown pin slipping clean. machining inside the raceway is smooth, BCG glides without drag
