M8 got give you credit i use to have an ion and hate the ****ing thing look so ulgy but this is one of the smartest ions i seen before nice job and good look with the sell if i had spare 300 notes i would buy
just to clarify from a few pm's i've received, the stage 5 replaces the entire top half of the marker (breach, firing can, eyes) and makes it a bolt out back so you no longer have to take your ion apart to get the bolt out.
