Bear Creek Arsenal's Bear Bolt Pro Puts a Turn-Bolt in AR-10 Dress
Bear Creek Arsenal is putting a turn-bolt action inside AR-10 architecture with its new Bear Bolt Pro, a 2026 rifle aimed at shooters who want manual operation without giving up MSR modularity.
Snapshot
American Rifleman reports that the Bear Bolt Pro replaces the multi-lug AR-style bolt of Bear Creek's earlier bolt-action with a one-piece, two-lug bolt requiring a 70-degree lift. It's offered as a complete .308 Winchester rifle or as an upper for existing AR-10 lowers, bringing conventional bolt-gun mechanics to a mil-spec-compatible platform.
Key points
- New bolt design: The redesigned upper houses a one-piece, two-lug bolt with a 70-degree lift and an out-of-battery safety that keeps the rifle from firing unless the bolt is fully locked.
- Two buying options: Bear Creek Arsenal lists the complete rifle at $674 and the upper-only version, compatible with most AR-10 lowers, at $399.
- Barrel and handguard specs: The initial chambering is .308 Winchester, with an 18-inch SOCOM-profile, 1:10-inch twist barrel in black nitride, paired with a 15-inch free-floating M-Lok handguard.
- Complete rifle build: Full rifles mate the new upper to a forged BC-10 lower with a Luth-AR MBA-1 adjustable stock, with total weight at 8.2 pounds.
- Future plans: American Rifleman notes Bear Creek intends to expand the Bear Bolt Pro into additional AR-10 configurations and eventually AR-15-compatible versions.
Quick take
This is a genuinely different approach to combining bolt-action shooting with AR parts compatibility rather than just another AR-10 clone, and the mil-spec parts support means owners can build it out with existing stocks, triggers and magazines. Worth a hands-on look once units reach dealers to see how the 70-degree lift and new ejection system feel in practice.
