When it arrives in the spring, SIG Sauer's SIG516 tactical rifle line for law enforcement officers will offer semi-auto and select fire variants, according to the company.
SIG introduced the rifle line at SHOT Show in Las Vegas, and will also make a civilian version.
The SIG516 rifles are gas-piston operated with a three-position (four-position optional) gas regulator; the design keeps the receiver free of firing residue for optimum reliability under adverse conditions and extended firing, according to SIG.
An optional three-burst mode is accessible with the fire control/safety selector that includes an ambidextrous design.
The line includes the SIG516 10-inch Close Quarters Battle (CQB), the SIG516 14.5-inch Tactical Patrol, the SIG516 16-inch Patrol, the SIG516 18-inch Precision Sniper, the SIG516 20-inch Precision Sniper, and SIG516 7-inch Personal Defense Weapon (PDW).
They come with a free-floating, aluminum quad rail fore end with four M1913 Picatinny rails for lighting and laser-mounted options. Barrels are chrome-lined and cold-hammer forged with a Nitride finish for durability and corrosion resistance.
The 18-inch and 20-inch Precision Sniper models feature heavy match barrels. The muzzle is threaded with a standard (0.5x28TPI) pattern to accommodate a variety of flash suppressors, muzzle brakes, and sound suppressor devices.
The lower and upper receivers are machined from aircraft-grade aluminum forging. The upper provides an M1913 Picatinny rail to accommodate a variety of optical sights. The upper and lower receivers feature a black, hard-coat anodized finish. Optional backup iron sights are available.
