The SIG556® HOLO features the same high-performance two position adjustable gas piston operating rod system engineered by Swiss Arms and marries it to a CNC machined from 7075-T6 grade aluminum forged trigger housing that not only cuts the rifle’s weight by a pound but is designed to accept standard AR magazines. The SIG556 HOLO features a 16” military grade cold hammer forged barrel, chambered in 5.56mm NATO, with a twist rate of 1 in 7”. The SIG556 HOLO has a proven two position adjustable gas piston operating rod system joined to a lightweight alloy trigger housing that accepts standard AR magazines. The vented non-slip polymer forearm has three Picatinny rails for accessory mounting. Sight options include front combat sight, flip-up rear sight, and a red dot style holographic sighting system that allows for quick target acquisition, with four illuminated reticle patterns with adjustable intensities. The SIG556 buttstock is collapsible and has a rubber butt pad and a number of sling attachment points. Select versions feature a folding stock with the ability to collapse, providing the best of both worlds.
