Have many of them. My fav would be my FN-15 tactical with 1-7 twist, m-lock hand guard, Moe sle furniture, Mft handguard, surefire mini scout, mbus front and rear, phase 5 nickel borron BCG, bmc gunfighter charging handle, Eotech HHS 2 hybrid sight with G33 magnifier, and socom rc-2 quick detach suppressor. One hell of a build and one hell of a gun. [spoiler]when suppressing don't forget to fill out that form 3!![/spoiler]
