Ensure your firearm’s safety and accuracy with the Forster Rimmed & Belted Headspace Gage for 8mmx57 Mauser. This field gauge measures 1.884” in length and is crafted from durable steel. Designed for precise testing, this gauge helps you determine if your rifle’s chamber is within SAAMI specifications. It identifies critical headspace conditions: a GO gage indicates your rifle can safely accept standard ammunition, while a NOGO gage warns of potential excessive headspace. Use the FIELD gage to check if your chamber is dangerously close to the maximum size, ensuring your safety on the range.
