Even though the Aimpoint Comp M4 has established itself as a top-tier optic, I think it’s important to give readers a balanced view by talking about the issues that users have reportedly encountered. 

I’ll share my expertise and recommendations in this article based on what I’ve learned and researched to make sure you fully comprehend the capabilities and potential drawbacks of the optic. 

So, let’s get started.

Aimpoint Comp M4 Problems To Be Aware Of

1. Battery Blues: When Your Power Source Fizzles Out

The Comp M4’s battery runs out of power unexpectedly or doesn’t last as long as it should.


  • Make sure the power source is installed correctly and with the proper polarity by checking it twice. A loose or incorrectly installed battery may occasionally be the root of a power problem.
  • Check to see if the battery contacts are clear of debris and dirt. If required, use a soft cloth or swab of cotton to clean the contacts.
  • Use new, high-quality batteries because old or inferior ones might not perform as well as you would like. Check the expiration date before use and spend your money on reliable brands.
  • Make sure the o-ring on the battery pack cap is in good shape and that the battery cap is properly sealed to prevent moisture infiltration. If necessary, swap out the O-ring.
  • Having extra batteries on hand is always a good idea, especially during prolonged shooting sessions or emergencies.

2. Dot Dilemmas: When the Reticle Doesn’t Play Nice

The red dot looks blurry, deformed, or has uneven brightness levels.


  • To carefully eliminate any dust, fingerprints, or marks from the lens, use a lens cleaning fluid and a microfiber cloth. Avoid using anything abrasive that might scratch the lens.
  • Try different brightness settings to determine what works best for your shooting environment. To keep a reticle crystal clear and visible, adjustments may be necessary depending on the lighting situation.
  • Make sure the optic is free of any obstructions or debris that might affect the reticle’s clarity. If necessary, carefully clean the interior parts by the manufacturer’s instructions.
  • Contact Aimpoint’s customer service if the issue continues for more guidance or to look into possible warranty coverage.

3. Mounting Mishaps: Keeping Your Optic Secure

The mount on the Comp M4 doesn’t keep zero or feels flimsy.


  • Mounting the optic on your weapon requires that you adhere to the manufacturer’s instructions. Make sure the mount is positioned correctly and tightly tightened.
  • The mount screws should be tightened according to the manufacturer’s instructions using a torque wrench or screwdriver. Under- or over-tightening can lead to a loose fit and damage the optic, respectively.
  • To help maintain a tight fit, add just a tiny bit of thread-locking compound to the mount screws. This can stop them from slipping loose as a result of vibration or recoil.
  • Check the mount screws regularly to make sure they haven’t gotten loose over time. To keep a tight fit, re-tighten them as necessary.
  • If the mount consistently gives you problems, think about spending your money on a superior, dependable mount made especially for the Aimpoint Comp M4.

4. Rainy-Day Woes: Battling Water Intrusion

When moisture or water seeps into the optic, it degrades performance.


  • Make sure all access points, including the battery cap, adjustment caps, and any others, are properly sealed and tightly fastened. Examine the o-ring seals and replace them if they are worn out or broken.
  • Even though the Comp M4 is waterproof, it’s nonetheless essential to keep it out of water or avoid immersing it for an extended period in heavy rain or water.
  • Remove the battery and let the optic air dry if water does get inside. Wipe away any moisture with a soft cloth. The use of heat sources should be avoided because too much heat can harm the optic.
  • Contact Aimpoint’s customer support if water intrusion occurs and impairs the performance of the optic for additional advice and possible warranty coverage.

5. Rainy-Day Woes: Battling Water Intrusion

The red dot’s illumination settings don’t correspond to the environment’s lighting well.


  • To change the brightness level to suit the lighting, use the buttons or rotary dial on the optic. Find the environment that offers the best visibility without causing annoyance or distractions by experimenting.
  • If you regularly utilize night vision equipment, think about purchasing a Comp M4 variant that is compatible with night vision gear. For dimly lit environments, these models provide additional brightness settings.
