đź”§ NEW PRODUCT RELEASE: Rifle Headspace Shims đź”§
Take the guesswork out of setting and measuring rifle headspace.
Our new Headspace Shims are designed for use with a GO gauge to accurately measure headspace when chambering a barrel, fitting a prefit barrel, or verifying chamber dimensions during installation.
How they work:
âś… Place the shim and GO gauge on the bolt face
âś… Insert into the chamber and close the bolt
âś… Increase shim thickness until the bolt no longer closes
âś… Add the shim thickness to the GO gauge dimension to determine actual headspace
Perfect for:
• Barrel chambering
• Prefit barrel installations
• Barrel nut systems
• Precision rifle builds
• Gunsmithing applications
Available for Small Bolt Face, PPC, Standard, and Magnum bolt face cartridges.
Whether you're building a competition rifle, installing a new prefit barrel, or dialing in chamber dimensions, our Headspace Shims provide a simple and repeatable way to achieve precise results.
