Definitely recommended

Brownells USA Necessary Tool 16/12/2017

Checking head space was easier than I thought. These gauges were quick and easy to use and the findings gave me a confident feeling about the new bolt that I installed on my AR 7.62x39. They should be handle with care as to not put any dings or scratches on them.

Definitely recommended

Brownells USA Only way to b shure 30/03/2017

Ordered this gauge set to check my ar build. They come nicely packaged and they proved their purpose. I really prefer to know if headspace is acceptable before I pull the trigger the first time. Maybe a bit spendy, but I'm guessing you could probably sell them and recoupe most of the cost. Gonna keep mine, kinda got the bug now, might just build another one.
