When it comes to mounting a red dot sight on an AR-style rifle, there are a few things you need to take into consideration. Of course, where you mount the sight will depend on the specific make and model of rifle you’re using, as well as your personal preferences.

That said, here are a few general tips to help get you started:

  • If at all possible, try to avoid mounting the sight too close to the barrel of the gun. This can cause sighting problems and also create excess heat around the red dot sight that could damage it over time.
  • It’s generally best to mount the red dot sight towards the rear of the rifle, opposite from where your thumb would naturally fall when holding the gun. This will help you keep a natural shooting grip while still being able to see the red dot sight.
  • Make sure that the red dot sight is properly secured to the rifle before firing. This is particularly important if you’re using an AR-15 style rifle, as the recoil can cause an improperly mounted sight to come loose and potentially fall off entirely.
  • Be aware that using a red dot sight will change your point of impact (POI) compared to using iron sights. This means that you’ll need to make appropriate adjustments to your zero before taking your rifle out to shoot with the red dot sight attached.
  • Always remember to turn off the red dot sight when you’re finished shooting for the day. Leaving it on can cause the battery to drain unnecessarily, and it’s also just good practice to get in the habit of flipping the switch off whenever you’re done using it.

By following these simple tips, you’ll be well on your way to getting the most out of your red dot sight on an AR-style rifle. happy shooting!

It depends on the type of red dot sight you’re using.

If it’s a tube-style sight, such as an EOTech or Aimpoint, then it goes above the barrel, just in front of the rear sight. If it’s a reflex-style sight, such as a Trijicon RMR or Vortex Venom, then it goes on top of the slide, directly in front of the rear sights.

Most optics are designed to be mounted in one specific way, so consult your optic manufacturer’s instructions to be sure you’re mounting your red dot sight correctly.

Also, be sure to check that your gun is compatible with the mounting system that your optic uses – there are many different types of rails and mounts, and not all red dot sights will work with all of them.

If you’re unsure about which red dot sight to buy, or how to mount it, then speak to a qualified gunsmith or firearms instructor. They will be able to advise you on the best way to set up your gun for use with a red dot sight.

The best place to mount a red dot on an AR-15 is typically just forward of the rear sight, where you have the most clearance and can still get a good sight picture. Some shooters prefer to mount them slightly higher on the receiver, but this can sometimes lead to problems with getting a good cheek weld. Ultimately, it’s up to the individual shooter to experiment and find what works best for them.

It depends on the type of red dot sight you are using. If it is a tube-style sight, it will typically mount on the top of the receiver. If it is a reflex-style sight, it will typically mount above or below the barrel. You should also consider what type of ammo you are using and how that may affect your point of impact. For example, if you are using FMJ ammo, you will want to mount your red dot lower on the gun so that your point of impact is not raised by the taller bullet profile. Conversely, if you are using a hunting round with a ballistic tip, you may want to raise your red dot so that your point of impact coincides with the point of aim.

It depends on the type of red dot sight you are using and the type of mount you are using.

If you are using a fixed red dot sight, then it can go on just about any flat surface on the gun.

If you are using a detachable red dot sight, then it will typically come with a mount that will allow you to attach it to a specific location on the gun. For example, many ARs have a Picatinny rail system that allows you to attach various types of mounts and accessories.

So if your red dot sight comes with a Picatinny-style mount, then you would attach it to one of the slots or rails on the top of the AR’s receiver. Other types of mounts can be used, such as those that clamp onto the barrel or ones that replace the rear sight.

It’s really up to you where you want to put the red dot sight on the gun. Just make sure that it’s mounted securely and that you have a good field of view through the sight.

If it’s a reflex sight, then it should be mounted as close to the bore axis as possible. This will help to keep your head down and minimize the sighting time necessary. If it’s a holographic sight, then mounting it higher will allow you to have a more “heads-up” orientation when sighting. However, be sure to remember that the further away from the bore axis that you mount your sight, the greater torque that will be applied to it when firing, which could result in accuracy problems.
