516 Patrol    
	
One of the most tested and proven weapons systems in the world achieves
ultimate refinement with the introduction of the Sig 516 rifle. With its
ambidextrous selector switch, chrome lined, nitride finished, military
grade barrel and adjustable, three position gas regulator, the Sig 516
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 bases rifle available.
