Heckler & Koch MR556A4 5.56NATO 16.5" 6 lands & grooves, right twist, 1 in 7 Rate of Twist Barrel 18" Barrel Including the Length of the Flash Hider Adjustable Stock 4.5-5.6 Pound Trigger Pull Optic Ready mounting rail Comes with one 30 round capacity magazine Arrives in the factory original box with a HK branded soft range case Quote from HK's Website- “Its short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components than direct-impingement ARs. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.”
