Helps Prevent Ammo-Related Malfunctions
Precision machined aluminum gauge is the quick, accurate, easy way to check reloaded ammunition—or suspect factory ammo—to verify that it is dimensionally correct for proper function in your rifle. A majority of semi-auto jams are caused by oversized cases; if your ammo doesn’t fit the case gauge, it won’t fit your chamber. Anodized red or blue for easy caliber identification. Red .223/5.56 Wylde gauge fits .223 SAAMI and 5.56 NATO. Blue .308/7.62 gauge fits .308 SAAMI and 7.62mm NATO.
