SIG SAUER SIG516
One of the most proven and proven weapon systems in the world achieves maximum refinement with the introduction of the SIG516 rifle. With its nitride-treated military grade barrel and adjustable four-position gas regulator, the SIG516 incorporates all the most desirable mechanical improvements. Add to these a free floating guard, and you have the most advanced and versatile AR rifle available. The SIG516 family of tactical rifles is the latest product of the US armaments division SIG-Sauer. Aimed mainly at the North American market, this family of weapons includes two basic semiautomatic versions, oriented to the civil and police market and another version with automatic selective fire destined to the government. The SIG516 is closely linked to the Ar-15 / M16 family of assault rifles, albeit with a number of improvements, such as a gas regulator for the piston recoil system.
The SIG516 uses a gas-driven recoil system configured as the Ar-15 / M16, with a mechanism drawer made of aluminum alloy with two sections, upper and lower. The Ar-15 / M16 style rotary bolt system has been upgraded with a short travel piston that moves inside the handrail, over the barrel. The gas group is equipped with a manually adjustable gas regulator. The trigger group, manual override and feed system are similar to the Ar-15 / M16. The SIG516 Patrol has a 16-inch chrome barrel and an adjustable M4 stock. The optical equipment is installed on the integral Picatinny rail above the gearbox or on the 4 additional rails of the handrails. The tactical world is full of ARs. But only a select few are tough enough and accurate enough to call themselves GIS. The SIG516 is the natural evolution of the platform, with a series of improvements designed to survive anything, anywhere.
This was designed for tough tactical environments, its advanced SIG SAUER short push lever system reduces carbon inlay, excessive heat and unburnt dust in action, ensuring unmatched reliability and function, a camera and a diameter of NATO Nitride 5.56mm guarantee a reliable function in any environment, It also has an adjustable gas valve that allows operators to increase gas flow when lower pressure ammunition is used or when adverse conditions require additional power. Reduced flow and off position improves the use of suppressors. The barrels have an A2 flash suppressor and are threaded 1/2 × 28 TPI, allowing the SIG516 to accommodate a range of replacement accessories and suppressor brackets. Whether you are left-handed or right-handed, there should be no compromise in shot performance, as the SIG516 features an ambidextrous selector, pin release, charger release, and load handle.
The SIG516 has a safety lever on the left side, to be used by the thumb of the firing hand. The gas block integrates an adjustable gas regulator. The front gas block has a bar to accept the front view with a rotating sight lamp post. The SIG516 models are equipped with a flash device with bird cage M16A2. All SIG516 models, except the Marksman, are equipped with 16-inch barrels wrapped in a floating M1913 Picatinny rail, as well as folding iron sights (BUIS) manufactured by SIG Sauer. The models N56 SIG516 of 5.56 × 45 mm accept magazines type box AR-15. These magazines are built in variants of 5, 10, 20 and 30 rounds. SIG516 Russian rifles should use a different charger, as they have a 7.62 × 39 mm camera. The Russian SIG516 uses chargers designed for AR-15 7.62 × 39 mm rifles. The rifle is a hammer and has a two-stage trigger mechanism in the Marksman SIG516, while all others have a single-stage military-specification trigger. A bolt retention device locks the bolt carrier assembly after the last magazine cartridge has been expended and is released by depressing the bolt retention lever located on the left side of the receiver. Alternatively, a left-hander may release the bolt by pulling the loading handle a short distance back.
