The SB (Short Barrel) configuration centers on a 16.5 in 4140 carbon steel sporter barrel that is threaded 5/8x24 and capped with a knurled thread protector. The setup is optimized for suppressed use while keeping overall length compact and handy.
The three-lug bolt design provides an approximately 70-degree lift for scope clearance and fast cycling. An oversized, grooved bolt knob offers positive purchase. Ejection is from a right-side port, and the action incorporates a two-position safety.
The synthetic stock features a black/gray camo finish with textured grip surfaces and a front sling swivel stud. Length of pull is factory 13.0 in and adjustable to 14 in via a removable spacer, allowing a tailored fit.
Feeding is via a detachable, flush-fit polymer box magazine for a 4+1 capacity in .300 AAC Blackout. A one-piece Picatinny scope rail is installed on the receiver to facilitate mounting. Both the receiver and barrel are 4140 carbon steel for strength and durability.
Manufacturing and markings are clear and direct: barrels are made in Spain using Bergara processes and the rifle is imported by BPI Outdoors, Lawrenceville, GA. Markings include MADE IN SPAIN and ES BPI LAWRENCEVILLE, GA.
