Sig Sauer SIG716 rifle
The SIG 716 is the new piston operated 7.62x51mm / .308 Win. rifle from Sig Sauer.
The rifle will be offered in four configurations:
- Tactical Patrol (12.5" barrel, almost certainly only on offer to law enforcement and military)
- Patrol (16" barrel)
- Precision Marksman (16" barrel)
- Precision Sniper (20" barrel)
Every model is equipped with free-floating quad rail and chrome-lined barrels. The Marksmen models feature heavy match barrels. The non-marksmen models come with backup iron sights. The 517 makes use of Armalite's AR-10 Gen II magazine.
According to pizzigr1 at AR15.com, Sig are using Armalite AR-10 Bolt Carrier Groups (BCG).
No word on pricing or availability.

Why don’t they just start making sig 550/551 ? They are stamped metal, it shouldn’t be too hard.
There’s already enough AR15 on the market.
Because this isn’t an AR-15. This is an AR-10 based rifle.
It’s very, very interesting that they chose the AR-10 (Armalite company) magazine rather than the KAC SR-25/DPMS LR-308/original AR-10 (division of Fairchild) magazine that otherwise seemed to be becoming the standard .308 AR magazine. I wonder why? And I wonder if this might prompt some aftermarket magazine makers, like C-Products and/or Magpul, to introduce .308 magazines in this design.
Because then they couldn’t piggyback on the popularity of the HK416/417 with their clever naming scheme.
Arg!!!!!!!!!!!! another AR-10 if they made M-1As id be happy.
SIG 550/551/556 is a 5.56×45mm weapon — a 7.62×51mm version would be cool but I’m not sure the folks at SIG want to create a brand-new rifle. The only recently new “black rifle” design in 7.62×51mm that I’m aware of is the Kel-Tec RFB. Everything else is a rehash of third-quarter of the 20th century designs (but there’s nothing wrong with that). I know this rifle is gas-piston vs. direct impingement but that’s not a drastic change (unless you’re scrubbing chambers a lot).
Hmmm… I see that they decided to include a forward assist. I’ve noticed alot of the .308/7.62mm AR series rifles do not have one. Interesting…
“I see that they decided to include a forward assist.”
DPMS offers them as an option on the LR-308. I had them use that version for mine.
I like that precision marksman unit, but wonder what it weighs.
I grabbed a product line catalog from Sig at SHOT and it lists this rifle as using “Standard M14 type steel magazine” on the product bullet points for it. Page 14 if anyone out there has one and wants to make sure I haven’t had one concussion too many. I was interested in a rifle that took M14 magazines, I’m not interested in this if its just another AR-10.
Sig already has made a 7.62 version of the 550/551/552. They called it the 542. Now if Sig redesigned that one to take the SR-25/DPMS/Magpul mags, that would be something.
El duderino : Well actually, there’s a SIG 55x in 7.62, it’s called the sig SAPR.
I noticed that the selector switch is not ambidextrous. In such a crowded product market, wouldn’t you want the small details like that to distinguish your product?
… I realize this may be a dumb question… but, is that a night vision apertures at the end to enhance night snipping? Be kind.
Papa, it sure is.
The sig 550 in 7.62 Nato does exist. It’s called SAPR 751, and it’s made by the real SIG, not “sig sauer in america”
It is still under devellopment (it has already been for a lonnnnnng time, for almost 3 years I’ve seen ads saying “coming late this year”)
In the latest pictures it looked like this.

The SIG716 will be very heavy due to the Magpul PRS.

Thanks Steve.

Cool
Armalite is running a sale on AR-10 magazines. Buy them now, if you are interested. I’ve never seen them this cheap.
Gimme a 542 that takes surplus G3 mags and I will sell alot of them.
well yes it will be heavy and i read that the 2 longer barrels are going to be marksman an sniper with heavy bull barrels ,so maybe an i hope sig will have a <1/2inch groups @ 100 yards. oh by the way magpul started making 308 mags i know for the dpms so they may fit this also an they was only about 20.00 bucks .i just want to see some reviews of this sig so i know where to go dpms or sig thanks
