SIG Sauer has updated the Cross bolt-action system for a more tactical feel, while keeping the rifle’s weight in check for when the user needs to be more mobile. 

It has the same receiver and stock as the standard Cross series rifle, but that's where the similarity ends. The new Cross STX ships from the factory with SIG's SLH/SLX suppressor-ready QD flash hider installed on 5/8x24 TPI threads on the muzzle of a 20-inch heavy barrel. Also, it carries an extended free float M-LOK handguard with a full-length 20-MOA top rail, rather than the short rail seen on the legacy Cross. This frees up real estate for things like modular optics and night vision.

The new SIG Cross STX, with its 20-inch heavy barrel and QD flash hider, runs 41.5 inches overall. However, keep in mind that the fully adjustable PRS-style SIG Precision Stock is side-folding, which drops the OAL to just 30 inches. (Photo: SIG)
