This SR40 airsoft sniper gun is manufactured by Classic Arms airsoft and is a full 1:1 size replica of the Military issue SR40 Sniper Rifle. The SR40 is manufactured in the new UK legal two tone black and blue colours, with textured and toughened ABS anti-shock resin plastic and metal, which has been carefully balanced so that main body is legal blue and barrel and extra parts remain black. The SR40 has an internal steel barrel with a decent body weight 2400g for increased sturdiness, which also provides the user with a realistic feel to the gun, plus the gun has a great build quality and no flexing. The gun has a realistic spring powered bolt slide action cocking mechanism, and the gun is a spring powered single shot sniper which makes gun inexpensive and easily maintained; as it requires no gas or batteries to operate. The SR40 feature both top and under barrel RIS rails to allow you to add a scope and/or bipod. The Classic Army SR40 sniper gun very will be effective in target competitions, with good accuracy, an output of 420fps and a firing distance range of up to 40+ metres. We recommend only using 6mm high quality polished BB ammo with this rifle.
