Simple & useful - EOTech M3X & M6X LED Bezel Upgrade Kit

Who wouldn't want to improve the run-time of their tactical light? It's a simple way to upgrade to LED technology for a moderate cost. Simply remove your old bezel, put on the new one and you're ready to go. You must use care when screwing on the new bezel so you don't strip the threads or damage the rubber O-ring seal. Also make sure it's tightened fairly snugly.
Pros: Easy to upgrade, improves product
Cons: Be careful when installing
