This thing is great. I can now put together my AR15 without worrying if the head space is up to par. Just be careful and don't slam the bolt home. And for better insurance, take the extractor and ejector off the bolt before you check. This is the NO GO gauge, so the bolt shouldn't completely close on it.

I bought the as a set of "GO, "NO GO" & "Field" from another vendor. If you are on a limited budget, you can do the headspace job with just the "GO" & "NO GO" gauges.

When I'm doing builds for clients, these are a MUST have item to insure head space is correct. These have saved me from building a unsafe AR platform firearm on more than one occasion when BCG bolt was found to be a few thousandths off spec which would have resulted in case rupture exposing the shooter to serious injury & damage to weapon.

The set I got had full instructions on how to use properly & what the reject/unsafe specs are. I recommend to those who do more than several AR builds a year have these gauges on-hand. For those who rarely do a build, a competent AR 'smith has these guages on-hand already & normally the labor cost is minimal. For those starting out, I suggest reading up on firearms chamber head spacing. These are precision, quality gauges & care must be taken with handling & cleaning for accurate tests. Prices seem to vary considerably among vendors. REMEMBER: If it is out of spec, DO NOT FIRE!

It is a precisely machined tool to make sure your gun is correctly machined and spaced for safe operation. It is well made.

Expensive but worth it. These will make you confident your headspacing is correct and that your rifle is good to go.

Very easy to use and handy to have to check all your AR rifles, or .223 caliber rifles for safety issue.
