This will cover the Receiver Bridge, Overall Height, and Barrel Band.
The measurement of the bridge is taken from the front of the receiver to the rear side of the bridge at the highest point. The spec range for this measurement is 3.935 – 3.925.
The overall height is taken from the front of the receiver to the highest point on the heel. The spec range for this measurement is 7.920 – 7.900
The barrel band is measured from the top/front of the receiver to the rear of the band. The spec range for this measurement is .701 - .698
It is important to note that SPEC’s are SPEC’s. There is no one better place to take a measurement other than the highest or lowest point.
The equipment that is used for this is calibrated Mitutoyo Height Master, Mitutoyo Heightmatic 600, and 2 digital Mitutoyo slide calipers on a Starrett Granite Surface Plate. This is the best equipment for this task, Not Gauge Blocks.
It will be needed to post a few reply's to get pictures loaded.
I hope this shows the right way to measure receivers.
