Poor quality control. Sent two “max” no “min” unfortunately was discovered after return window expired. Buyer be warned. One star is too much!

Hard to imagine anyone completing or trouble shooting an AR build without these gauges. Must have items to ensure the safety and reliability of a hobby/home build device.
wayne Blankenship Verified Buyer – 14 January 2025

Returned. Both gauges exactly the same length! That is terrible quality control considering what these are used for. Spend a bit more and oeder fosters

Just added to my “MUST HAVE” tool kit for DIY AR15 build. Great product, quality and price.

These are good quality and work perfectly. These are an important tool for builders, or if certain parts have been replaced.
Sam Agee Verified Buyer – 4 April 2025

Gauges are not in spec at all despite being a max and min gauge, they’re the same OAL. These gauges could get someone killed with improper headspacing avoid at all cost
