About This Firearm
The Sig Sauer 716i Tread is a direct-impingement semi-automatic .308 Winchester built for range shooting and hunting. It has an MSRP of $1,519.99. Sig built it by taking the features of its SIG516 onto an AR-based rifle in 7.62 NATO, with a free-floating barrel inside an alloy fore-end.
One 20-round magazine comes with it. The receiver rail is M1913 Mil-Std and the fore-end is M-LOK, and the SL-K stock has six positions. The trigger is a single stage with a polished hard-coat finish. The 5/8x24 muzzle comes bare, so a brake or a suppressor mount is a separate purchase.
If you’re cross-shopping, the Ruger SFAR is a used buy at 6.80 lbs, 1.7 lbs lighter, with a fixed mid-length gas system and a brake on the same 5/8-24 thread. The FN SCAR 17S has an MSRP of $3,999 and runs a short-stroke gas piston under a telescoping side-folding stock, at 8.90 lbs. The Sig is the one built on an AR lower, so the controls and the parts are the ones AR shooters already own.

Strengths & Limitations
- Sig’s Infinite Guarantee covers the rifle with no receipt and no warranty card, and it transfers to the next owner with the gun.
- The M1913 rail runs the length of the receiver, so a magnified optic and a red dot behind it both have room.
- The barrel is carbon steel under a hard coat anodized receiver, and the whole rifle is AR-pattern, so a gunsmith who knows an AR knows this one.
- No sights are fitted, so an optic is the first thing the rifle needs.
- There is no gas adjustment, so running it suppressed means living with whatever comes back.
- One magazine comes with it, and at 8.50 lbs the rifle is already heavy before glass and a loaded magazine go on.
