What’s Included
- Allen BakTrak padded rifle sling
This Accumark features Weatherby’s 9-lug Mark V action with a short 54° bolt lift for smooth cycling and generous scope clearance. The spiral-fluted bolt reduces weight while enhancing debris clearance in harsh conditions.
The stainless #3 contour barrel is fluted for heat dissipation and threaded 5/8-24 to accept the factory-installed Accubrake ST or a compatible suppressor. A 1:10 RH twist stabilizes heavy .338-caliber bullets, making full use of the .338-378 Wby. Mag.’s high velocity.
An externally adjustable TriggerTech Field trigger allows the shooter to fine-tune pull weight without disassembling the rifle. The three-position safety offers secure operation while permitting bolt manipulation on safe.
The hand-laid fiberglass Monte Carlo stock includes aluminum bedding pillars and a palm-swell pistol grip for a solid, repeatable shooting platform. A Pachmayr Decelerator pad further mitigates recoil, complementing the brake’s effectiveness.
Finished in graphite-black Cerakote over stainless steel, this rifle is built for durability in demanding environments while maintaining Weatherby’s SUB-MOA factory accuracy guarantee.
