EGW Case Gauge Ammo Checkers are machined from solid 6061 T6 aircraft grade aluminum.
While some companies use boring bars to make chamber checkers, we use the actual Clymer reamers that are used to chamber barrels.
Anodized matte black for durability.
Measures min case diameter.
Measures max overall length.
Note for 223/5.56: The difference between the .223 and 5.56 case gauge is the 5.56 has a longer throat. The bullet is still seated to the same depth.
