While we’re on the subject of the button: it’s got a great feel to it, with a very short throw that makes the EMI Avenger very easy to activate. Firing of the mod was very consistent, and we did not experience any misfiring. We were also rather impressed with the reverse-threaded locking ring. While this type of lock design is quite common on bottom-button mods, the ring on the Avenger is quite tall and easy to grab, and turns very easily. While using this type of lock can often be a bit cumbersome, and can frequently lead to accidentally unscrewing the bottom of a mod, this happens to us less often on the Avenger than most mods with a similar locking system, because the ring turns so smoothly that it’s easy to tell when you’re at either the fully locked, or fully unlocked, positions.
