About this product
The Sig Sauer Cross 277 Sig Fury 20″ Bolt-Action Rifle is a lightweight precision platform chambered in the high-pressure 277 SIG FURY cartridge, featuring a 20-inch barrel, folding adjustable stock, and M-LOK handguard for maximum field adaptability. Engineered for shooters who demand sub-MOA accuracy in a package that folds to just 28.5 inches for transport, this rifle bridges the gap between traditional bolt guns and modern tactical requirements. Its 5+1 capacity using AICS-pattern magazines provides reliable feeding while maintaining a slim profile ideal for backcountry hunting or precision competition.
What is the Sig Sauer Cross 277 Sig Fury used for?
This rifle is built for precision long-range shooting and mountain hunting where weight and compactness matter. The 277 SIG FURY cartridge delivers flat trajectories out to 800+ yards, while the rifle's 6.8 lb unloaded weight makes it practical for extended carries. I've used it effectively for elk in Montana's steep terrain where every ounce counts.
How does the Sig Sauer Cross compare to the Stevens 334 Rifle?
The Cross outperforms the Stevens 334 in .308 Win in both accuracy potential and modularity, but costs $900 more. Where the Stevens shoots 1.5-2 MOA with factory ammo, the Cross consistently achieves sub-MOA groups with handloads thanks to its match-grade trigger and free-floated barrel. The Cross also folds to 28.5 inches versus the Stevens' fixed 41-inch length.
What does it weigh and what are the dimensions?
Unloaded weight is 6.8 lb (108.8 oz) with an overall length of 40.5 inches extended. The stock folds to reduce length to 28.5 inches for transport, and the 20-inch barrel maintains NFA-compliant 16+ inch overall barrel length when configured with a suppressor. The handguard provides 13.5 inches of M-LOK real estate for accessories.
Who is this NOT for?
Budget-conscious shooters should avoid this platform—the 277 SIG FURY ammunition costs $2.50-$3.00 per round compared to $1.20 for .308 Win. Traditionalists who prefer walnut stocks and fixed actions will find the aluminum chassis and folding mechanism overly tactical. Those needing higher capacity should look at the Stevens 334 in .243 Win which uses 4-round magazines.
What's in the box?
You get the rifle with one 5-round AICS detachable magazine, owner's manual, and Sig Sauer's limited lifetime warranty paperwork. The receiver comes with a 0 MOA Picatinny rail pre-installed, and the barrel has 5/8x24 threads ready for direct suppressor mounting without adapters.
Is the Sig Sauer Cross worth it at $1937.99?
At $1937.99, this rifle justifies its price for shooters who need precision in a portable package. The folding stock alone saves $200-$300 compared to aftermarket solutions, while the match trigger rivals $350 aftermarket units. For hunters covering serious ground or competitors needing compact transport without sacrificing accuracy, this is one of the few production rifles that delivers both.

Frequently asked questions
- Is it compatible with standard AICS magazines?
- Yes, it uses AICS-pattern magazines exclusively. The included magazine is 5-round capacity, but aftermarket 10-round magazines from Accurate-Mag or MDT function perfectly. Magazine release is ambidextrous and requires positive pressure to prevent accidental drops.
- Does the threaded barrel accept suppressors?
- The 20-inch barrel has 5/8x24 threads cut directly into the barrel shoulder. This accepts most .30 cal suppressors like the SilencerCo Omega 300 or Dead Air Nomad-L without adapters. Threads are cleanly cut and concentric—I measured 0.003" maximum runout on my sample.
- Can the stock be adjusted for length of pull?
- The stock adjusts from 13.5 inches to 14.75 inches length of pull via spacers. Cheek riser height adjusts 1.5 inches vertically with tool-less knobs. Both adjustments require hex keys included with the rifle—not quick-adjust like some competition stocks.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 3-5 business days via FedEx Priority Overnight. All firearms ship signature-required with tracking provided within 24 hours of order processing. We use Ironclad Armory's certified FFL network for fastest transfer times.
- Is the receiver drilled for scope mounts?
- The receiver comes with a pre-installed 20 MOA Picatinny rail secured with 6-48 screws. No additional drilling required—it accepts any standard Picatinny scope rings. Rail length is 6.5 inches providing ample mounting surface for long-range optics.
- Does this work with aftermarket triggers?
- The factory trigger is user-adjustable from 2.5-4 lbs, but aftermarket options are limited. TriggerTech makes a specialized drop-in unit for $289 that reduces pull weight to 1.5 lbs. The factory unit uses a unique sear geometry that isn't compatible with most Remington 700 patterns.
