Quick Shipping, works

by -

Quick shipping and works to replace my Eotech 512 A.65 terminals. they got damaged from leaky alkaline batteries. learned my lesson and will be using lithiums from now on. This is only for the terminals and gasket inside the unit, if you have a worn battery box, you'll need to buy a new one (Pre or Post 2008 style), or buy the 9-N Bumper Kit, which EoTech used to sell but it's no longer on their website or on Primary Arms. From what I've been hearing, the replacement battery cover does not have the EoTech logo on it, so that's a bummer if you need to replace it.

Simple fix!

by -

Hadn’t been to the range in a while and my 512 started flaking out, I thought maybe it was done for. Pulled it apart and could see the contacts were corroded due to neglected alkaline batteries. Checked one that was on another gun and it was the same way. Two of these kits fix them both for cheap! Easy install.
