Here's the final look of Mikhail's signature gun: the Special Operations Forces Combat Rifle- Heavy or SCAR-H which is a Belgian-American battle rifle chambered for the hard-hitting 7.62mm NATO round, for Mikhail though the standard 7.62 round wasn't enough for him. So he started to use the M61 150.5-grain armor-piercing variant of the 7.62 NATO round. And to tell the difference between the standard ammo and his Armor-Piercing ones, he marked them with red tape on the magazines.
For attachments it's got an EOTech Hybrid Sight system which allows him to transition between long to medium and short range engagements easily, a vertical foregrip to reduce the kick felt by the weapon and a PEQ-15 laser emitter to help aim the rifle. Also he modified the standard flash hider of his SCAR-H by cutting out vents on the top of it to act as a compensator for the gun's recoil.
And two of the most unique modifications on his weapon is that the gun is under-gassed, meaning that the gas pressure lower than normal, slowing the guns rate of fire from 625 rpm to a stable 580 rpm. And the most unique is it's Super Select-Fire trigger system by Giessele Automatics.
