This is, without a doubt, the highest quality tool of its type. This is not a piece of plastic, but a lathe-turned piece of aircraft-grade, color-anodized aluminum with heavy-duty O-rings to center and retain it in the upper receiver while cleaning through it. The newest design is now equipped with a solvent hole located at the ejection port. Avoid damage to the chamber, throat, and crown of your expensive rifle. This cleaning rod guide is ridiculously overbuilt. Use it once, and you will not clean without it.

Unlike other case gauges, ours is cut with an actual match chamber finish reamer so it not only checks head space but also case diameter. A common problem for reloaders with high-grade rifles with tight chambers is out-of-spec ammo that will not go into battery. If you have a high-grade barrel with a tight chamber, this is the only sure way of assuring that your ammo is compatible. Most gauges only check head space. Some also indicate minimum and maximum case length. Only the JP gauge checks min/max headspace, min/max case length and case diameter relative to typical match-grade chambers.
