The Forster 220 Swift No-Go Gauge (brand part no. HG0220N) is a precision steel headspace gauge that checks for a 220 Swift chamber cut too deep during barrel fitting. Forster Products machines it to a fixed 1.81-inch length marking the upper edge of acceptable new-build headspace; if the bolt closes easily on this gauge, the chamber needs correction before the rifle is fired. Used together with a go gauge, it brackets the safe headspace range for this high-velocity varmint cartridge during a rebarrel or custom build. Add it to the rest of our gunsmithing tools and gunsmith supplies for precision rifle builds.

Frequently Asked Questions

What does it mean if the bolt closes on this no-go gauge? The chamber has been reamed too deep and the barrel work needs correction before the rifle is safe to fire regularly.

Is a no-go check necessary on a factory 220 Swift rifle? It’s mainly used to verify custom chamber work rather than an unmodified factory rifle, though it can confirm a factory chamber is within spec if there’s a concern.
