The M40 bolt action sniper rifle is used by the United States Marine Corps and is based off the Remington M700. Tokyo Marui have done an amazing job with this rifle, the stock is sturdy and textured just like the real one and the cheekpiece can also be adjusted by two low profile bolts on the right hand side. The rifle comes with 4 spacers which allow you to change the thickness of the butt plate to assist in eye relief when aiming down a scope. It has a cool cocking indicator which shows if the rifle is cocked or not and the short-stroke bolt allows you to operate the rifle accurately and quickly. Furthermore it has an adjustable trigger unit so you can set the 'biting point' for the rifle to fire.
Just like it's competitors, namely the VSR-10 & L96 it has a large number of upgrades available should you want to push it to the famous 500.
