    Perfect fit and look for my EPS Carry. Delivery was fast.

    I have never lost an optic battery screw before and when it happened the battery, battery tray and screw went flying. I looked everywhere for the screw, could not find it and was done shooting for the day. This is a perfect replacement screw, but does need a really small hex wrench to install. I bought a couple of extra just to have on hand. I think that the EPS Carry which comes with the battery installed, is prone to not having initially a tight screw and I didn’t think to tighten that little screw before use. Thankfully Tacrig had them on hand and immediately shipped them to me.

    Does exactly what you need the screws to do — hold the battery tray for the EPS Carry in place. Will need an 1.5mm allen/hex key for install, the screw(s) don’t come with one.

    Screw head diameter is about 1-1.5mm too large to sit flush with tray. Fixed this by throwing the screw head into the chuck of my drill and sanding the outside profile down. Not the greatest solution for most people. Since this is my carry gun I am now concerned that I’ll start to see rust on the screw where the black oxide coating has been removed.

    Arrived within a couple days of ordering. The fit is very good.

    After installing my eps carry, I bought it as a backup because you just never know, and you won’t find this at the local hardware store. I think it was shipped before I bought it because it arrive in a day and a half. Tacrig ships faster than the a-mazon. Thank you for another great purchasing experience!
