The Proof Research 284 Cal 22" Bolt Action Barrel Blank is engineered for shooters building a custom rifle around one of the most versatile medium-range cartridges in the field. This carbon fiber wrapped barrel blank arrives ready for a gunsmith to chamber and thread to your exact specifications, giving you control over headspace, twist compatibility, and final barrel profile. The Sendero Light contour balances weight savings with rigidity, making it a smart choice for hunters and precision shooters who need to carry their rifle without sacrificing performance over distance.
Built with Proof Research's reputation for accuracy and durability, this 22-inch blank features a 1:8" twist rate suited to a wide range of 284 caliber loads and bullet weights. The carbon fiber wrap adds strength while reducing overall weight compared to steel-only barrels, an advantage whether you're glassing a ridgeline or settling into a shooting position. Five groove rifling provides reliable bullet engagement and is a proven design across match and hunting applications.
This is a barrel blank—not a complete assembly—so your gunsmith will handle final chambering, threading, and fitting to your action. If you're building a rifle from the ground up or refreshing an existing bolt gun, starting with a quality Proof Research blank sets the foundation for accuracy and longevity.
| Caliber | 284 |
| Barrel Length | 22" |
| Twist Rate | 1:8" |
| Contour | Sendero Light |
| Grooves | 5 |
| Barrel Breech Diameter | 2.5" |
| Shank Diameter | 1.20" |
| Weight | 2 lbs 12 oz |
| Construction | Carbon Fiber Wrapped |
This is an unfinished barrel blank, so it requires professional gunsmith work. Your smith will need to chamber it to your desired specifications, cut and thread the muzzle end, and fit it to your bolt action. Do not attempt to install an unchambered blank yourself.
The 1:8" twist is a standard rate for the 284 caliber and will stabilize a wide range of bullet weights and designs commonly used in hunting and precision shooting. Your gunsmith or ammunition supplier can recommend specific loads once the barrel is chambered.
The carbon fiber wrap reduces weight compared to a traditional all-steel barrel of the same contour, though the exact savings depend on the final configuration your gunsmith creates. At 2 lbs 12 oz, this blank is already a relatively lightweight option in the Sendero Light contour.
Compatibility depends on your action's bolt pattern, threading, and headspace requirements. Work with your gunsmith to confirm fit before ordering, as barrel blanks are custom-fitted during the chambering process.
