Sig Sauer Cross Cross27720B Cros 277 20 5R Blk

The Sig Sauer Cross in 277 SIG FURY is a modern bolt-action rifle built on military-proven cartridge technology and engineered for hunters and shooters who want magnum performance without the weight. This 20-inch rifle delivers velocities over 3000 fps with 150-grain ammunition—enough power for medium to large game—while staying light enough to carry all day. At 7.3 pounds with magazine, the Cross 277 SIG FURY balances capability with practicality, making it equally at home on a long-range precision range or glassing for elk in rough country.

The Cold Hammer Forged Steel barrel is threaded 5/8"-24 for suppressor compatibility and features a tapered profile that promotes superior alignment. The one-piece receiver design keeps things simple and rigid. A 15-inch free-floating M-LOK handguard gives you flexibility to attach gear exactly where you need it, while the folding adjustable precision stock lets you dial in your fit and collapse the rifle down for transport or storage. The 2-stage adjustable match trigger breaks cleanly, and comes set up ready for an optic—there's no iron sights here, just Picatinny optics-ready mounting.

Shipped with one 5-round AICS-pattern polymer magazine, the Cross is ready to head to the range or field immediately. Its compact footprint (38.5 inches overall length, 3 inches wide) and anodized receiver finish mean it'll handle rough conditions without fuss. Whether you're a precision rifle competitor, a serious hunter, or someone looking to explore what 277 SIG FURY can do, the Sig Sauer Cross delivers modern rifle engineering in a package that doesn't ask you to compromise on capability or convenience.

Frequently Asked Questions

What optic should I mount on the Sig Sauer Cross 277?

The Cross is optics-ready with a standard Picatinny rail receiver—any modern riflescope with standard Picatinny rings will work. For a rifle built on this platform, we'd recommend something appropriate for your hunting or shooting style, but the choice of glass is entirely up to you.

Can I use a suppressor on this rifle?

Yes. The barrel is threaded 5/8"-24, a common magnum diameter. You'll need a suppressor rated for that thread pitch and capable of handling the 277 SIG FURY cartridge. The tapered barrel profile supports superior suppressor alignment.

What magazines work with the Sig Sauer Cross 277?

The Cross accepts AICS-pattern magazines. One 5-round polymer magazine is included with the rifle. Additional AICS-compatible magazines in various capacities are available separately.

Is the stock adjustable, and can it fold for storage or transport?

Yes. The precision stock is both adjustable for fit and designed to fold, giving you flexibility to customize your fit and compress the rifle's profile for transport. Overall length is 38.5 inches in shooting configuration.
