TFB Review: SIG CROSS PRS in 6.5 Creedmoor

Designed with precision in mind, SIG’s new CROSS PRS in 6.5 Creedmoor is packed with new features. Using the existing CROSS chassis, the PRS features a prominent new 24-inch heavy contour barrel underneath a new ARCA-equipped handguard. I was curious to see how this new longer-barreled variant was, and SIG was kind enough to send over a completely decked-out copy for me to review.

TFB Review: SIG CROSS PRS in 6.5 Creedmoor

The CROSS PRS features the same skeletonized folding stock as the original rifle. A slight redesign adds a bag rider to the bottom of the stock for smoother follow-up shots when using a rear bag.

Folding the stock is easy by pushing down the button at the rear and pulling the stock up and to the right. These stocks are a little stiff from the factory but have absolutely no wobble when locked in place. The stock also has tool-less adjustments for the butt pad, length of pull, and comb height.

While the CROSS features an AR-style safety, the CROSS PRS has a new safety design. When the safety is off, the oversized safety on the right-hand side acts as a thumb rest, allowing you to float your thumb for precision shots.

New to the CROSS lineup is the addition of this full-length steel ARCA rail underneath the handguard. With tripods and ARCA bipods all the rage, this is a very welcome addition to the CROSS PRS.

The barrel on the cross PRS is as heavy as they come with a thickness of .9 inches (23mm). SIG was kind enough to send this rifle over with their new SLH 7.62 Inconel QD suppressor that I quickly attached to the 5/8×24 muzzle threads on the cross.

For glass, I’d be using a SIG-supplied Tango 6, specifically the new 5-30x56mm. This first focal plane optic features SIG’s MRAD DEV-L reticle with 0.1 MRAD adjustments for both windage and elevation. With the rifle bore sighed, it was time to zero the rifle and get some data on the ammunition SIG provided.

Accuracy and Velocity

With the rifle bore sighted it was time to get some data on the SIG OTM Match 140 Grain ammunition. With the help of my trusty MagnetoSpeed, I was able to gather the following information based on a 20-round string of fire.

SIG CROSS PRS 24″ — SIG OTM 140 Grain Match Grade 6.5 Creedmoor

• Shots – 20
• Minimum – 2677 FPS
• Maximum – 2714 FPS
• Average – 2696 FPS
• Standard Deviation – 12 FPS

*Box listed muzzle velocity for this ammo is 2690 FPS.

My initial three-round group didn’t look like a three-round group at all. I had to actually walk downrange to find this ragged hole in the paper. It’s one of those groups that say “This gun shoots better than you, so if you miss, it’s your fault”. With this in mind, I went ahead and shot 5 more five-round groups, and here’s the result.

• Group 1 – 0.736 MOA
• Group 2 – 0.585 MOA
• Group 3 – 0.362 MOA
• Group 4 – 0.296 MOA
• Group 5 – 0.484 MOA

Average – 0.492 MOA

*Note: The best group of 0.15 MOA was not counted as it was only three rounds. Rifles like this mean the shooter is usually the weak link.

Range Time

Before we get into how the rifle performs, please understand the intended audience for this rifle. Out of the box, this rifle weighs 14.2 pounds, and as pictured it weighs in at 18.6 pounds (unloaded). It is a purpose-built precision rifle designed for PRS shooters or bench rest enthusiasts. And in that regard, it is fantastic.

I’ve never been fond of ambi safety selectors as I’m corrected-handed. I will however admit that this thumb rest on the CROSS PRS is a fantastic design. The fluted bolt is incredibly smooth and precise follow-up shots can be done incredibly fast once you’re used to the rest.
