Made to precise tolerances, the SIG716 Patrol is an accurate big bore ready for critical missions. Built with an adjustable piston operating system, the SIG716 runs reliably, even in harsh environments.

The weapons industry has introduced a plethora of new rifles chambered in 7.62x51mm NATO (.308 Winchester) for military, law enforcement and civilians alike. Many are based on the AR platform, with guns running the gamut from designated marksman rifles to battle rifles and carbines. Now in production and making its way to the market is Sig Sauer’s SIG716 series of guns. The SIG716 is the larger sibling of the SIG516 in 5.56mm NATO, and I couldn’t wait to get my hands on it to see what it could do.

Sig Sauer is known for reliable handguns that are used by law enforcement, many of the government’s “lettered” agencies and the U.S. Navy SEALs. They also produce high-quality rifles. For “tactic-cool” folks, the SIG716 looks like an M4 on steroids, merging the familiar AR platform with the 7.62mm round’s punch. The rifle comes in a hard gun case with a cleaning kit, a manual, a gun lock, a Magpul PMAG, a sling fitted with a pair of quick-detach swivels and a set of Sig Sauer-designed front and rear folding sights. Out of the box, you’ll immediately notice the SIG716’s superb fit and finish, something you’d expect with a Sig Sauer weapon. The rifle is solid and leaves no room for doubt that you’ve surpassed the realm of 5.56mm weaponry. The base rifle weighs in at 9.3 pounds without a magazine. As with many of the piston rifles I’ve handled, it felt just a little bit nose-heavy; however, the rifle is well balanced overall. The SIG716 is available in black with black furniture, black with OD green furniture, and Flat Dark Earth with matching furniture.


Specs At A Glance

The rifle is chambered for 7.62x51mm NATO and is compatible with .308 Win­chester ammunition. The receiver is mach­ined from a forging. This semi-automatic’s fire control selector is clearly marked with a “safe” or “semi” on both sides of the receiver, with a traditional 90-degree throw. The lower receiver also features an ambidextrous magazine release. The triggerguard can be opened by depressing a spring detent to facilitate trigger accessibility for a shooter wearing gloves.


The SIG716 uses an ad­­­vanced short-stroke gas piston operating system. According to the company, “the short-stoke piston system provides for lighter recoil, a faster cyclic rate, and it does not negatively affect accuracy like a long-stroke system would.” With the short-stroke gas system expelling gas at the piston, you may be wondering if there are any issues with mounting tactical accessories like optics, lights, lasers, etc. over that position, but very little gas is released—most of it is used to operate the rifle.

At the front of the quad-rail forend, just above the barrel, the SIG716 gas adjustment valve has four positions: normal; adverse, for conditions when there may be fouling; suppressed, which is the setting for use with a sound suppressor (the partial gas cutoff allows the weapon to cycle); and off, which allows the rifle to function as a single-shot weapon. The 16-inch, free-floating, match-grade heavy barrel is chrome-lined with a 1-in-10-inch right-hand twist. The A2 birdcage flash suppressor is affixed to the muzzle end of the barrel via a 5/8-24-TPI thread pattern. This is the industry standard for 7.62mm NATO rifles, which allows the shooter to change or remove the muzzle brake as needed.
