The SIG SAUER CROSS Magnum 300 Win Mag 24" rifle is a bolt-action hunting rifle built around a user-changeable stainless-steel barrel, folding precision stock and free-floating M-LOK/ARCA handguard. Its adjustable two-stage match trigger, 20 MOA Picatinny rail and six-round AICS steel magazine provide a versatile configuration for field use and precision-oriented shooting.
The SIG SAUER CROSS Magnum is chambered in 300 Win Mag and fitted with a 24 in stainless-steel medium-contour 5R barrel with a 1:9 twist. The user-changeable barrel uses 5/8 in-24 threading with a 90-degree shoulder and is equipped with a radial brake. Its free-floating handguard combines M-LOK and ARCA interfaces, while a 20 MOA Picatinny rail provides an optic-mounting platform. The folding precision stock is adjustable and reduces the rifle to 35.8 in when folded for transport. A forward-angle PRS-style grip, ambidextrous PRS thumb-rest safety and two-stage adjustable match trigger with a 2.5 to 4 lb pull support shooter adjustment. Feeding is handled by an AICS-compatible six-round double-stack steel magazine. The rifle weighs 8.7 lb in this 300 Win Mag configuration.
