King Arms SIG 556 DMR

The real steel SIG 556 is a semi-auto rifle based on the SIG 55X series. With semi-auto action and converted to take STANAG magazines, it is targeted at the civilian market; its longer variant DMR (designated marksman rifle) is its more recent model designed for match shooting. In the case of Airsoft, this translated to an AEG with a whopping 550mm inner barrel. A fully trademark licensed weapon; this AEG does a fairly decent job of replicating the look of the real steel. 

With an electro-pneumatic blowback system, this weapon cycles the dummy bolt on each shot. The bolt cycle has a distinct metal on metal sound making it rather different then most blowback electric rifles. 

The combination of metal and polymers do a good job of giving it a nice rifle heft but spreads out the weight to keep it fairly well balanced. The rather heavy PRS stock actually works well to balance out the long front with front wired battery storage. 

The receiver has a flat top rail and the foreguard has a long rail on the bottom for bipods and / or grips with short rails on the sides towards the front for lasers and flashlights. Selectable of semi and full-auto which is not realistic strictly speaking but is useful for Airsoft games and if you do not like it you can always just not use it. 

It does take King Arms M4 magazines in this case coming with a short type 190 round high capacity version. Technically, as such, it is compatible with Marui magazines but it is a tight fit probably requiring some minor filing; it is recommended just to use King Arms magazines which is easy enough considering there is a massive variety of them and they are all more then good enough for gaming. 

It comes with a Magpul style PTS PRS stock which is highly adjustable and just the right stock for a marksman style weapon. The weapon does make use of an M4 style stock tube to attach stocks so for those who want to know it can indeed take M4 style stocks if you intend to change it although you should always ask to double check if your proposed stock will fit this AEG. 

Equally so, with 360 fps its good enough for outdoor use but if you want to crank up the power you can look into getting a juicer spring. This weapon does not come with a battery or charger, nor does it come with a scope or bipod either so if you want to pick one up take a look around the website, you are sure to find something you might like.
