EOTech EXPS2 Problems

Last Update:

Welcome to my blog about EOTech EXPS2 problems.

Today, I’m delving into a subject that has been generating a lot of discussion among gun enthusiasts: the Eotech EXPS2 issues. 

Instead of simply repeating the same dull facts that you can find elsewhere, I won’t do that here. I’ll tell you everything that happened, along with my suggestions for fixing the Eotech EXPS2 problem.

EOTech EXPS2 Problems To Be Aware of

There are indeed some prevalent problems to be aware of. But do not worry, as many of these problems can be quickly fixed with a few easy fixes.

1. Zero Shift in Extreme Weather Conditions

Have you ever been frustrated while trying to aim at a target only to discover that your sight has been forced to zero by bad weather? When moving from a cold to a hot environment, this problem is frequently experienced. 


  • Allow your sight to become accustomed to the temperature changes before using it. 
  • To prevent damage to your sight from sharp temperature changes, use the thermal shield or sight hood, respectively. 

2. Battery Drainage

Users of the Eotech EXPS2 beware! Have you ever been dissatisfied by a dead battery right when you needed your sight the most? If your Eotech sight is not turned off completely after use or is left on for a prolonged amount of time, battery depletion may result. 


  • To prolong the life of the battery in your sight, be sure to correctly switch it off after every use. 

3. Washout in Bright Light

Every shooter had once experienced this: you line up for the ideal shot, only to lose sight of your reticle in direct sunlight or other intense light sources. 

Avoid letting bad visibility undermine your hunting trip! In these circumstances, the reticle on the Eotech EXPS2 may appear scrubbed out or challenging to see. 


  • With your sight, employing a kill flash or sunshade can help lessen glare and increase reticle exposure. 

This will enable you to maintain your focus and consistently hit your target. 

4. Mounting Issues

Don’t let a bad mount destroy your shooting! Incorrect mounting or an unsecured mount could prevent the Eotech EXPS2 from mounting correctly or cause it to come loose while in use. 


  • Be sure to mount the sight according to the directions provided by the manufacturer. 
  • Before using it again, inspect the mount for damage or signs of wear. 

You can make sure your sight is firmly in place and prepared to assist you in hitting your target every time by doing this. 

5. Blurry or Distorted Reticle

Have you ever found yourself straining to see a fuzzy or distorted reticle? This frequent problem can be aggravating for any shooter. 

Things to consider first, a dirty lens is frequently to blame. 


  • A microfiber cloth can do wonders by just wiping the lens. 
  • Stay away from harsh cleaning agents because they can ruin the lens and make the problem more severe. 
  • It may be necessary for the maker to substitute or fix the reticle if it is broken. 

You can get an unobstructed view with your Eotech EXPS2 and never fail to take a shot once you follow these easy steps!

6. Parallax Error

Have you ever been annoyed by the fact that despite having your sight on a thing, you still missed it? A parallax error might be to blame. This frequent problem happens when the shooter’s eye is not lined up with the optical axis of the sight. 


  • Proper sight alignment and eye relief adjustment can help assure that the reticle is centered in your field of view. 

Spend some time setting up your sight correctly before your next shooting session to get the best outcomes. Your targets won’t have any idea what struck them!
