The MANSON PRECISION 300 PRC GO Headspace Gauge ensures firearms have the SAMMI-recommended minimum chamber depth for safety.
Mixing brands of headspace gauges can lead to inaccurate readings due to tolerance stacking; it is advised to use gauges of the same brand and caliber together.
The gauge is made from M7 high speed steel, is in-the-white, and hardened for durability and a long service life.
