I used to be instantly intrigued by the Sig Cross at SHOT Present 2020, the place we have been simply starting to see the explosion of sunshine, folding-chassis looking rifles, and the Cross turned an enormous participant in that market. Regardless of wanting nothing like a standard looking rifle, combining AR and precision rifle ergonomics in a conveyable, fully-adjustable platform made the Cross an interesting alternative for hunters and shooters of all sizes. In actual fact, our Taking pictures editor John B. Snow has advised me tales of getting to wrangle a prototype pattern in 6.5 Creedmoor again from a buddy who was lower than prepared to half with it due to the absurd quantity of elk the rifle had killed. 

There hasn’t been loads of selection within the Cross rifle, however in typical Sig trend, they’re increasing the road to fill within the gaps, making the Cross line extra versatile, user-friendly, and now appropriate with magnum cartridges. Just like the AR, the Cross is a machinist’s gun. The platform is good for potential modifications and elements compatibility. Sig formally launched the Cross Magnum, chambered in .300 Win. Magazine, in late 2023. I jumped on the likelihood to get one, and have burned over three kilos of gunpowder attending to comprehend it. I’m not reducing the Sig Cross Magnum any slack — extra on that in a bit — however I feel it’s a platform that opens a wide range of potentialities to magnum rifle followers.

Fundamentals of the Sig Cross Magnum

There aren’t any shockers for shooters who’re aware of the Sig Cross lineup. The Sig Cross Magnum isn’t a lot completely different from the primary one we checked out again in 2020. It contains a strong anodized aluminum receiver, AR-compatible grip, and AR-style thumb-select security. It’s received a fully-adjustable folding inventory and free-float aluminum handguard. The rifle pairs with AICS magazines and has a single-piece Picatinny rail atop the receiver that extends barely out over the handguard. Like the unique Cross, the Sig Cross Magnum is easy, glossy, and versatile. This new mannequin does embrace a number of key updates too, and never only a magnum-length motion and longer barrel.

The Inventory

The folding inventory on the Cross Magnum is intuitive and straightforward to regulate on the fly. It’s adjustable in 4 planes and, with out instruments, will be match to simply about anybody in a matter of seconds. Size of pull will be modified by loosening the wingnut-like screw on the starboard facet of the inventory, then transferring the butt in or out and retightening. The butt pad will be moved up or down between 5 completely different settings by urgent the small triangular button on its facet and transferring it the place you need it. Butt pad angle will be modified by loosening two set screws and rotating the pad clockwise or counter-clockwise. The comb pillars are spring loaded and when the toggle lever is launched, the comb pops as much as its full top. You possibly can modify on the fly by merely urgent the comb down together with your cheek till your head place is right, then lock the toggle. I discovered this adjustment to be useful for various shooters and on-the-fly-adjustments for awkward taking pictures positions.

The largest distinction between the Cross Magnum inventory and the one on the unique Cross is the hinge launch. The Sig Cross Magnum’s hinge makes use of a button latch that, when pushed, permits the inventory to swing to the folded place, over high of the bolt deal with. The unique Cross used the basic push-pin-downand-lift design to unlock the inventory. This new one is sturdier and simpler to function.

The Handguard

Glossy accent compatibility is without doubt one of the Cross rifle’s strengths. The essential Cross rifle options an aluminum float tube with M-Lok slots for attaching bipods, QD sling mounts, or different equipment. The Cross Magnum does all that, but additionally incorporates a full-length ARCA rail on the underside. Shooters can connect an ARCA or M-Lok bipod, and nonetheless have loads of ARCA close to the receiver for mounting on a taking pictures tripod. The handguard attaches to the receiver through three pairs of T15 screws at 10 o’clock, 2 o’clock, and 6 o’clock.

Grip and Controls

Although the grip is appropriate with different AR grips, it’s good to see Sig go for a chunky, vertical PRS-style grip for this rifle somewhat than one thing extra generic. The up to date fashion of security levers that the Sig Cross Magnum makes use of are an ergonomic praise to the grip. Like the unique Cross, the rifle employs an ambidextrous AR-style security lever, however the Cross Magnum has one with inbuilt thumb rests on either side. The combo units up a pleasant, ergonomically sound grip, and permits good set off management.

The magnum-sized AICS journal can accommodate cartridges as much as 3.850 inches in size. seats simply and securely within the receiver, and the journal launch is a low-profile twin paddle contained in the entrance of the set off guard. It’s intuitive to function with the set off finger for both right- or left-handed shooters, however will also be depressed with the off-hand thumb whereas pulling the journal free. Every tab has good ribbed texturing, however is rounded and doesn’t protrude outdoors the width of the journal properly — an amazing characteristic for a hunting-focused rifle.

The Sig Cross Magnum’s Versatile Bolt

Many key options of the Sig Cross and Cross Magnum rifles lend to their potential versatility. The bolt is simply a kind of parts. The bolt physique has the identical diameter because the three locking lugs, which makes for a reasonably slick motion. It’s received a 60-degree bolt throw that’s crisp and lightweight on the carry. 

The firing pin meeting and bolt deal with are simply faraway from the bolt physique with out instruments, as is the bolt head and retaining pin — making it a possible shoe-in for pre-fit barrels and bolt heads for different calibers. The barrel is connected to the receiver much like an AR. It has a barrel extension that slides into the receiver and is secured by a barrel nut. A variety of corporations already make pre-fit barrels for the unique Cross, and that i’d count on to see them right here too.

The bolt head contains a small Sako-style sliding extractor in one of many lugs, and makes use of spring ejection. One factor I seen about my pattern is that the bolt head solely employs a single ejector. The Sig Cross Magnum consumer handbook exhibits a twin ejectors.

 I had no operate or ejection points with my take a look at rifle however, when drawing the bolt again very slowly, the ejector would typically spin instances round within the receiver somewhat than spit them out on the bench or taking pictures mat subsequent to me for straightforward assortment.

Adjustable Two-Stage Match Set off

The set off is my solely actual dig on the Sig Cross Magnum. Maybe I simply drew a foul one — such issues occur — however it’s a element I’d pay shut consideration to if shopping for one. I actually like two-stage triggers for precision work, in all probability a results of my service rifle days. I’ve two huge points with the set off on the Sig Cross Magnum that I’ve. First, the set off on my take a look at pattern is just too gentle. For a looking rifle, the 1 pound 3 ounce set off weight is just too gentle — I’d go so far as to say dangerously so. Second, an much more alarming problem is that the distinction in weight between the primary and second stage is just too small. 

The Consumer handbook particulars the set off as being adjustable between roughly 2.5 and 4 kilos. As shipped, mine broke at 1 pound, 3 ounces as measured by my Lyman set off pull gauge. The distinction between the primary and second levels at any given adjustment level was solely 2 to 4 ounces.

If you happen to’re unfamiliar with how a two-stage set off works, it’s fairly easy. The primary stage of the set off is slack. As you add weight and press the set off, it strikes again easily till stopping abruptly in opposition to a wall of resistance. The second stage is including power in opposition to this (hopefully) inflexible resistance, lastly working the sear firing the rifle. A clean first stage and heavier second stage enable a shooter to softly add strain to the set off till it breaks. 

The Sig Cross Magnum set off adjusts through a T15 screw within the entrance of the set off guard. On the gentle finish of the adjustment vary, the primary and second levels have been tangible and distinct. A number of occasions although, I misplaced focus and blew proper via the primary and second levels, firing a shot earlier than fully prepared. I explored the complete adjustment vary, and on the heaviest setting, the set off pull measured 2 kilos, 12 ounces. Nonetheless, as a result of the levels are solely a pair ounces aside, I may now not really feel the cease on the second stage and it simply felt like a long-pulling set off. A set off with these traits is just not one which I would like.

Taking pictures the Sig Cross Magnum

Within the discipline and on the vary, the Cross Magnum captures a lot of what makes the Cross platform a fascinating rifle. For a 24-inch-barreled precision-styled rifle, it’s fairly compact — solely 36 inches lengthy when folded up. As talked about, it’s extremely adjustable and appropriate with all kinds of taking pictures aids. With little or no effort, it may be arrange for stomach taking pictures metal arrays, clipped right into a tripod for standing pictures, or bagged for assist. The price of going to a magnum-length motion? It’s a lot heavier than the compact Cross fashions. 

With no journal, the naked weight of the gun is just below 9 kilos, and fitted with a cantilever mount and Sig Whiskey 6 3-18 x 44 scope, it’s 11 kilos, 2 ounces. In comparison with most mountain rifles, that is absurdly heavy, however inside its peer group, the Cross Magnum isn’t extreme. That bit of additional weight together with its vary of adjustment and radial muzzle brake make taking pictures this rifle a pleasure. Even and not using a brake, the recoil impulse isn’t too sharp.

With a titanium suppressor, the Sig Cross magnum is even nicer to shoot. I shot the rifle with three completely different suppressors: a Silencer Central Banish .338, Banish Backcountry, and a Silencero Scythe Ti. The endcap brake on the Scythe made it the softest-shooting of the three, however for carrying across the mountains, the Banish Backcountry is equally as interesting.

Accuracy

I used to be initially underwhelmed by the Sig Cross Magnum’s accuracy however, all issues thought of, it’s not as dangerous because it sounds. I recorded 37 5-shot teams throughout 9 various kinds of ammo and located the rifle to be choosy. Most manufacturing facility ammunition averaged teams within the 1.5- to 2-inch vary, and the gun solely shot one manufacturing facility load properly. 4 teams of Barnes Vor-Tx 165-grain TTSX averaged .975 inches. 

Two of the three hand masses I examined averaged higher than many of the manufacturing facility stuff. The most effective-shooting of these was one I developed for my Fierce CT Rival, taking pictures 212-grain Hornady ELD-X bullets with 69.5 grains of RL 22. They averaged 5-shot group sizes of 1.16 inches (5 teams) with the manufacturing facility muzzle brake and, apparently, .79 inches (5 teams) whereas utilizing the Silencerco Scythe Ti suppressor. It’s a small pattern measurement, however each units of teams have been fairly in step with .22- and .23-inch commonplace deviations. The primary solely had one sub-inch group, and the second solely had one group that measured greater than an inch.

One other good-shooting load used Lehigh Protection 175-grain Managed Chaos copper bullets atop 79 grains of H1000. My 10-shot experimental group with that load measured 1.06 inches. An combination of the very best 10 5-shot teams, which we’ve got been utilizing to indicate a rifle’s potential, is .800 inches.

My takeaway from accuracy testing with this rifle is that it’s able to actually good accuracy, however you’ll have to sift via the canine to search out what it likes. That’s not out-of-character for a production-chambered .300 Win. Magazine. In comparison with my Fierce CT Rival, which averaged 1.02-inch teams general and averaged .599-inch teams with the 212-grain ELD-X load, the chamber within the Cross Magnum has roughly .030-inch extra freebore till the bullet hits the lands.

What the Sig Cross Magnum Does Nicely

The Sig Cross Magnum is an correct, extremely versatile platform that may pull precision-rifle responsibility whereas remaining fairly gentle and compact when folded. Essentially the most thrilling factor in regards to the platform is the potential of simply switching between magnum barrels and calibers.

The place the Sig Cross Magnum Might Be Higher

The largest fault of my take a look at pattern was the set off. Although with nice focus it allowed exact taking pictures, it’s too gentle for a looking rifle, and the second stage wants a bigger distinction in pull weight. As a looking rifle, the inventory parts are a bit snaggy in comparison with a clean artificial inventory. 

Closing Ideas on the Sig Cross Magnum

In itself, the Sig Cross Magnum is a cool rifle that’s clean to function, acceptably correct, and extremely adjustable. It’s not as nimble because the quick motion, however I feel it’s well worth the cash. Seeing the markets which have emerged for OEM and aftermarket Sig upgrades for his or her pistols, I’ve little doubt that shooters will begin seeing them for the Cross Magnum. Pre-fit carbon barrels and easily-swapped bolt heads would enable this platform to deal with nearly any affordable magnum. It’s a pleasant rifle, and I feel its versatility and utility will solely get higher with time.
