🔧 NEW PRODUCT RELEASE: Rifle Headspace Shims 🔧
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:
✅ Place the shim and GO gauge on the bolt face
✅ Insert into the chamber and close the bolt
✅ Increase shim thickness until the bolt no longer closes
✅ 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.
