EGW USPSA Magazine Length Gauge

The Evolution Gun Works magazine length gauge is the official manufacture for the USPSA. The EGW gauge is constructed of 6061 aircraft aluminum with a durable anodized finish. The gauge features a 140.25mm measurement for "Limited Class" magazines and a 170.25mm measurement for "Open Class" magazines. This is the same measuring device used at all major USPSA events for checking magazine length.
