Sometimes optics come down to personal preference. Our two red dot choices for carbines are the Aimpoint T2 (or M5) and EOTECH series. The EOTECH has the clearer glass of the two options, which becomes particularly useful when engaging at longer distances.

The EXPS3 sits at a lower 1/3 co-witness height. Back up ironsights can be seen inside the window, but in the lower 1/3 of the optic. Buttons on the left side allow you to toggle through the 20 daylight brightness settings, and the NV button switches to a dim mode for use with night vision. The optic can be seen in NV mode by either running a PVS-14 mounted to the rail behind the EOTECH, or by getting a cheekweld while running bino NODs.

So, what is the difference between the EXPS and the XPS?
Watch this video that covers the basic differences between the two. The biggest difference is the height at which they sit on a rifle.
How does the EOTECH EXPS 3 compare weight-wise to a T2?
An Aimpoint T2 with a Scalarworks LEAP is 4.97oz, the EOTECH EXPS3 is 11.2oz. If you want to know more about how the EOTECH compares to the T2, you can read our article about it here.
You can’t leave the optic on all the time. Is this a problem for home defense? What’s the auto shut off like?
It could be. The EOTECH is definitely a more intensive product. You have to manage it more than an Aimpoint. If you turn on/adjust the optic with the up arrow brightness setting, the auto shut off is 8 hours. If you turn on/adjust the optic with the down arrow brightness setting, the auto shut off is 4 hours. The 8/4 hour shut off is toggled by the last push button used. And resets once a button is pressed. Pretty cool actually.
How clear is the glass?
In our opinion, the EOTECH series appears to have the clearest glass of any optic available right now. Making it very handy for longer range shooting. Combine that with the crisp 1 MOA center dot and you’re golden.
Are the EOTECHs good now? Wasn’t there some sort of scandal?
There was. The responsible parties were dealt with, reparations were made to both the military and commercial market. The question shouldn’t just be: “Was there wrongdoing?” The question should be: “How was it dealt with? Were things made right?” If things hadn’t been made right, we wouldn’t be selling EOTECH products.
