Eotech EXPS3 initial Cold Weather test

[azoutdoorsman]

I did a little experiment with my EO today:

No zero shift that I could discern. The front and rear lenses on the EOtech were a little fogged up from condensation, but it was on the OUTSIDE of the lens and wiped off easily.

Sight was outside approximately an hour. Checking the zero against the sights eliminates ammo as a variable, but is less precise than actually firing the rifle. However, I am confident that I could have hit a torso at 300 yards before and after the temp change.

UPDATE: I left the upper in the trunk of my car overnight where it reached 23F last night. No shift. I didn't take a pic because it looks like the other two, and it's not THAT much colder than the first test. When it gets closer to 0F I'll do it again.

What are you still doing with an EOTech??

Yeah, I've used mine in temps from the mid 90°s to the -10°s and never experienced any zero shift either.

There are thousands who cannot say the same. When all of this happened, I was amazed how fast people turned on the products they had been standing by for years.

Got it,all of the EOtech issues are made up.

I'm positive that's not what the OP meant. EOtech clearly had issues, hence the findings of the Government, but that still does not translate to every shooter using their products.

Before this recent hubub, I had never heard of zero shift problems, had you? Battery terminals failing, dimming reticle yes, but never the temperature dependent zero shift.

Then, the report comes out and suddenly thousands of users return their (still functioning) units for a full refund.

I like your comment "I am not a freeloader".So anyone who has had a issue with there EOtech like I have had with mine and sent back to EOtech to make it right is a freeloader?Just curious? If your EOtech is trouble free good for you.Don,t lump all folks into one basket who have had issues with there EOtechs.

The same crowd who bought them because of the .mil use are now returning them because of the lack of .mil use, regardless of issues.

I'm keeping mine.

No there were few, if any, reports of zero shift before this report because "most" people will never use them in those conditions.

Regardless, it is a free country for the time being and people can do as they see fit.

Let me see, the company lied, committed fraud, covered up and built iffy sights but still has happy end users. Well I hope when they finally fail it will not be at a time when they are truly needed but knowing Murphy.......
