Very good fit overall 5 stars

Got it for the Ec4s it is Awesome.

I purchased the Nitecore Tactical Crenelated Bezel specifically for my SRT7. The SRT7, not being as compact as the MH12 or MH20, serves a a backup which I keep on my night-walking pouch instead of in the neoprene wrist holder.

As a backup, it is readily accessible in the event that I have to use it for self defense. The crenelated bezel is more than substantial enough to fend off a pit-bull bezerker, more intimidating than holding a flashlight up to my mouth and flashing a set of fake vampire teeth and growling like a werewolf! Ha Ha!!

As well, it may also be used for breaking auto glass in the event I have to rescue a drunk driver wrapped around a tree! The way these people drive down here in West Palm, they may be 'distracted' by the shiny lights coming off of Buddy's and Skippy's (my Havanese and PBGV) safety vest! An ironic possibility as hilarious as it may seem!

Durable and looks like it would more than handle a given situation if needed.

Turn your Nitecore SRT7 into a self defense tool with this attachment and increase damage protection from drops.
