About
What it is, and why it matters
The SIG Cross is a modular bolt-action precision and hunting rifle introduced by SIG Sauer in 2020. Built around a one-piece aluminum receiver with an AR-style ergonomic pistol grip, ambidextrous safety, and an M-LOK precision handguard with a full-length Picatinny top rail, it bridges the gap between a lightweight hunting rifle and a precision platform. A floating bolt head and barrel-nut system allow the user to swap barrels without a gunsmith, and the folding, fully adjustable precision stock lets the shooter tune length of pull and comb height. Chambered most commonly in 6.5 Creedmoor, it feeds from AICS-pattern detachable magazines and uses a two-stage match trigger.
SIG Sauer marketed the Cross as a do-everything modular rifle that could transition from a backcountry hunting gun to a long-range target rifle, leaning on the company's experience with the modular MCX/MPX systems and the .277 SIG Fury cartridge developed for the U.S. Army's Next Generation Squad Weapon program.
The Cross was offered in 6.5 Creedmoor, .308 Winchester, and the proprietary .277 SIG Fury. The folding stock and tool-less barrel swap system were among its headline features. Early production examples were subject to a 2021 recall related to the firing mechanism, after which an updated trigger and bolt design were introduced.
