556-NOGO : 5.56mm NATO Caliber Headspace No-Go Gauge for AR15 / M16 Armorers Kit
SKU
154488
This high quality machined steel gauge determines excessive headspace in the barrel's firing chamber, as well as too much chamber depth, or an undersized bolt.
A bolt that closes on a No-Go gauge means that a chamber is close to the maximum chamber size. Etched with caliber marking, and "NO GO" designation. Machined to SAAMI specifications.
Made in the USA.
