About
What it is, and why it matters
The Sig Sauer Cross is a lightweight bolt-action precision rifle designed to bridge the gap between backcountry hunting rifles and long-range precision platforms. Weighing just 6.5 pounds, the Cross features a folding stock, one-piece aluminum receiver, and SIG's two-stage match trigger in a package significantly lighter than most chassis-based precision rifles. It was developed by the same SIG Sauer engineering team responsible for military programs including the XM7/MCX SPEAR.
The Sig Sauer Cross was developed in response to a growing demand from backcountry hunters who wanted precision rifle accuracy in a package light enough to carry on extended mountain hunts. At just 6.5 pounds, it challenged the notion that chassis-system precision rifles had to be heavy, and its launch coincided with SIG's expansion into virtually every firearms category following their U.S. military M17/M18 pistol contract win.
The Cross was unveiled at SHOT Show 2020 and represented SIG Sauer's first entry into the bolt-action precision rifle market. The rifle uses a proprietary short-action receiver machined from a single billet of aluminum and accepts standard AR-15 pattern magazines in its short-action chamberings. The two-stage Matchlite Duo trigger is adjustable from 2.5 to 4.4 pounds. The stock folds to the left side for compact transport.
