SIG Sauer Cross STX tactical features

The stock of the SIG Sauer Cross STX is foldable and adjustable.

“The Cross STX is the result of input the from professional end-users looking for extreme performance in a lightweight, long-range platform,” they say at SIG. The Cross was designed from the start as a modular design, and the STX variant uses in fact the same receiver and stock as the standard Cross, but with the addition of some tactical features starting from the 20” heavy barrel equipped with an SLH/SLX suppressor-ready flash hider in QD configuration and the free float MLOK handguard with full length 20 MOA top rail. This means that you have a one-piece rail extending from the rear of the rifle up to the front of the handguard, ready for the mounting of scopes, night vision or any other accessory you want.

The ambidextrous external paddle release of the SIG Sauer Cross STX
is located inside the trigger guard.

The folding precision stock has an adjustable cheek rest and Length-of-Pull (LOP), and when folded the rifle's overall length is just 30 inches (762 mm). The two-stage match trigger is adjustable too.
