The SIG 516 Tactical Patrol by King Arms is an exquisite airsoft gun. Other than the fact that it is another M4 variant, the body design and front assembly are quite unique. The lower receiver of the SIG 516 contains licensed trademarks as well as a different lower receiver design. Another great addition to this airsoft gun are the ambidextrous features which is a great plus to left handed shooters. The ambidextrous mag release features a similar design to the MK16 and MK17 variants, easy to access and manipulate. There are four QD mounts located on the left and right side of the gun which allows the user a wide array of options to securing their rifle. The upper rail platform is similar to the monolithic rail systems, providing the user with an uninterrupted platform for mounting their optics at the proper distance. Internally, the SIG 516 contains high quality performance parts from King Arms such as a reinforced steel gear set, polycarbonate piston, ported piston head, and more. Overall, this is a unique airsoft gun designed to provide one of the best performance on the field.
