Aaron Cowan over at Sage Dynamics has some of the most extensive information available on the topic of pistol optics and their durability in a realistic duty sense.
Not every optic is meant to be an M&P rated item, yes that is more than just a Smith & Wesson trademark. They are all not meant for the military, the police, serious competitive events, training, or hard use ccw gun. They aren’t and they do not have to be. I don’t need an RMR on a 10/22 that mostly exists for my kid to enjoy range time or for a task no more serious than controlling damaging critters.
Thus enter the EOTech EFLX.
Now EOTech is a well known and well respected duty optic brand. The HWS line has served and continues to serve as an excellent optical series in the reflex sight category. Their magnifiers are exceptional glass quality. Their LPVO and high power rifle optics in the VUDU line have all seen well respected success.
Their VUDU 1-8x SFP is one of my favorite LPVOs, arguably my favorite SFP one. However, their initial 1-6 offering left a lot to be desired in its design. I feel like, and Aaron’s report here supports that belief, the EFLX is going to be another proof of concept optic where a follow on variant solves many of the deficiencies of the first version.
Does that mean you should avoid buying an EFLX? Maybe. You can arguably get a dot with better performance under harsh handling conditions for similar spend, so why wouldn’t you. However if you want it just because [reason] and its limits are not detrimental to what you are trying to do with it, then pick it up now. If you want to wait or buy something more suited to your task, then do so.
