The 20" barrel is cold hammer-forged steel and threaded 5/8x24 with a tapered shoulder for suppressor alignment. It uses a 1:10 twist to stabilize modern .277 SIG FURY projectiles and is paired with a free-floating system for consistent barrel harmonics.
The action is a right-side bolt with an oversized bolt knob for confident manipulation. Controls include an ambidextrous manual safety and a two-stage, adjustable match trigger that enables a crisp, predictable break.
Chassis features start with an aluminum receiver finished in black anodizing and a 15" aluminum alloy M-LOK handguard. The handguard provides M-LOK slots at 3, 6, and 9 o'clock for accessory placement while keeping the barrel free-floated.
The stock folds for compact storage and transport and includes an adjustable length of pull and cheek riser, plus a recoil pad. Length of pull is set at 13.0". The rifle uses a SIG polymer pistol grip for a secure, repeatable hand position.
For mounting solutions, the receiver carries a 20-MOA Picatinny top rail. The rifle has no installed sights and is configured for optics via the integral rail. Feeding is via an AICS-pattern detachable box magazine interface; one 5-round Magpul polymer magazine is included. The receiver is roll-marked "CROSS" and "MULTI CAL," and the factory box label matches the receiver serial. Made in the United States.
