3. Bushnell Trophy TRS-25 Red Dot Sight Riflescope.

Recoil is your guns’ direct reaction when a bullet leaves the barrel of your weapon.

You see, when your bullet clears the crown of your rifle’s barrel, it is normally followed by some gasses from the powder’s combustion.

It is these gasses that cause recoil as they exiting from the barrel.

Now, recoil doesn’t directly affect accuracy but if it’s greater, it does affect your follow-up shots- you may, in fact, have to re-aim.

So, we intentionally decided to add a red dot that can hold up to recoil from even big guns.

And that is where the Bushnell trophy red dot sight comes in. It excellently resists recoil.

Incidentally, it is very bright and differentiating targets in dimly lit conditions is very easy.

3.  Dagger Defense DDHB Red Dot Reflex sight, Reflex sight optic.

A red dot uses a low power LED to produce the reticle. In comparison, holographic sights use a high powered laser to create the holographic impression of the reticle.

Critics of holographic sights will tell you that they are bulkier, drain batteries much faster and perform purely in locations where temperatures change quickly like mountains.

Among the red dots that have slowly built a name is The Dagger Defense red reflex sight-a pedigree red dot build to withstand the rough-and-tumble of changing weather conditions.

Moreover, it is built from the toughest aircraft grade aluminium, thus it is quite a sturdy optic.

Furthermore, it uses a square shaped window to impose either a green or red dot based on your tastes and prevailing conditions.

Then, each of the 2 dots has two reticles so it has a total of four different designs.

Equally important is the fact that the optic has many different brightness settings, from dim to the brightest. its one of the best scope for ar 15 under $100.
