None of the Forster Rimless Headspace Gage's are available in 450 Bushmaster. And unfortunately, we do not carry any other options for 450 Bushmaster.

Helpful Positive Review Head space gauges by K1847, November 28, 2017
Best tools when a new barrel is being to your rifle. Best used with an A15 or SR25. Simple to use, just follow the instructions provide with each gauge. Have fun with your next build. It is recommended toe gauge your new barrel before installation.

I've always been satisfied with all the Forster products I have. This is no exception. Nicely finished and packaged.
Most Recent Reviews perfect companion for the go guage by slkzic, Verified Owner, December 14, 2023
Just used it last night to head space a new 22 Creedmoor barrel. Now I’m ready for some coyotes. Will probably get out to the range to break the barrel in next week sometime. Next purchase will be a thermal or NV scope.

Product Info for Forster Rimmed & Belted Headspace Gage

Headspace is the distance between the face of the breech and the base of the cartridge when the action is closed, and excessive headspace can be dangerous as well as impair accuracy. For instance, unsupported brass fired in a rifle action with excessive headspace can rupture, allowing gas to blow rearward like rocket exhaust. Because your safety is on the line, Forster Headspace Gages are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifle's chamber.image

If a rifle closes on a GO gage, the rifle chamber will accept any ammunition that is made within SAAMI (industry standard) specifications. If a rifle closes on a NOGO gage, the rifle chamber might have excessive headspace. Most gunsmiths chamber a rifle's headspace between the GO and NOGO dimensions. If a rifle closes on a FIELD gage, the rifle chamber is dangerously close to or already over the SAAMI specified maximum chamber size.
