The Fulfilled Potential Of The AR-15/M16

One of the most tested and proven weapons systems in the world achieves ultimate refinement with the introduction of the SIG516 rifle. With its chrome-lined, phosphated, military grade barrel and adjustable, three-position gas regulator, the SIG516 incorporates all of the most desirable mechanical improvements.

Add to these a free-floating quad rail forend and barrel, and you have the most advanced, versatile AR-based rifle available.

• Gas piston operating system
• Three-position gas regulator
• 5.56 x 45mm NATO
• Free-floating military grade chrome lined barrel
• M1913 Picatinny flat top upper
• 7075-T6 Aircraft grade aluminum upper & lower receiver with hard coat anodize finish
• Flip-up iron sights

This is a NFA weapon and requires a Form 3 transfer to your local SOT / Class III dealer and then a Form 4 transfer to you by the local dealer. Make sure this weapon is legal in your state prior to purchase.
