The Composite Stalker configuration pairs a matte black/blue metal finish with a black composite stock featuring a straight comb, molded texture panels, sling swivel studs, and a recoil pad. Length of pull is 14.0 in, offering a straightforward fit and clean shoulder mount.
The action uses a three-lug bolt with a 60-degree lift, a design that keeps bolt travel short while maintaining solid lockup. Feeding is via a detachable box magazine with a 4+1 capacity in .270 Win, and the tang-mounted safety includes a bolt-lock override for controlled operation.
The 22 in sporter-profile barrel is button-rifled, free-floated, and capped by a recessed crown. It is unthreaded and set up from the factory without iron sights. The receiver is drilled and tapped, and this rifle arrives with a one-piece Picatinny base and rings already installed.
Proof marks indicate manufacture by Miroku in Japan, with Browning's serial code prefix YW denoting 2024 production and the 358 model code identifying the AB3 series. This aligns with the rifle's recent-release status and current factory configuration.
