Carbon Pre-fits (Barrel Nut Style)
Unlock Your Rifle’s Potential with IBI Precision Prefit Barrels
Transform your shooting experience with our precision-engineered prefit barrels. Designed to utilize a robust barrel nut system, our barrels allow you to perform a full caliber swap in just 5 minutes—right in your own shop. Whether you're switching from .308 to 6 Creedmoor, you can master multiple disciplines using the same action, chassis, and scope.
Key Features:
- DIY-Ready: Easily fit up at home with standard tools and headspace gauges.
- Ultimate Versatility: Maximize your investment by running one rifle platform across multiple calibers.
- Compatibility: Pair with our premium barrel nuts, wrenches, and muzzle brakes for a complete setup.
Important Build Notes: Barrel nuts are not included with the barrel; please add them to your cart if needed. When ordering for Savage platforms, note that shank sizes are not caliber-specific. The Savage small shank tenon is 1.06″; any measurement above this is a large shank.
(Please note: Due to the specific production process for our carbons, all barrels must come with muzzle threads)
