Here are some of the 7 best prism sights at 1X and higher magnifications.

Shooters with bad astigmatism are finding them more useful with better reticle clarity than red dot sights. In addition, prism sight inherently forces the shooter to center the eye behind the optic to eliminate all parallax shift for more accurate shots.

Vortex Spitfire AR - Best Overall 1X

Why Use A Prism Scope? This is by far the best prism scope for AR15 at a decent price. This is for any users with astigmatism, open division shooting competitors, and truck rifle setup without worry about the battery life or the reticle disappearing. 

Clear Glass Etched Reticle - See the reticle clearly even if you have astigmatism using the diopter adjustment. It works differently than a red dot!

Trijicon ACOG 3.5X - Best Durability

Trijicon ACOG 3.5x35 Dual Ill Riflescope w/Mount, Green Crosshair .308 Reticle

Why Use Trijicon ACOG - The Trijicon ACOG scope is the standard-issue fixed magnification optic for the US military. It's built like a tank to survive any damages that a new 18 yr old military recruit could possibly do, knowing that they don't usually take care of their issued gears. So it's bombproof.

Improved Eye Relief - Unlike the ACOG 4X where the shooter has to get very close to the ocular lens. The 3.5X model gives more eye relief distance for better cheek position.

Tighter Shot Groups - Aim with the Chevron tip as fine as your eyesight allows is as fine as you can zero the sight without a minute of angle

Various Reticle Options - Tons of fast aiming reticles to pick from. We recommend the ACSS reticle for fast ranging and target acquisition.

Daylight Reticle Illumination - Fiber optics illuminates the reticle even in low light conditions as long as it's not completely dark.

Aim Both Eyes Open - Trijicon's Bindon Aiming Concept allows shooters to aim with both eyes open for improved situational awareness.

  • Magnification: 3.5X
  • Objective Lens: 35mm
  • Eye Relief: 2.39"
  • Reticle Type: TA11 BDC
  • Turret : 0.33 MOA / Click
  • Length: 8 inches

Why Try This One - If you want what the U.S. special forces use in real world applications, the dual role (1-4X) ELCAN prism sight must be on the list for CQB and mid range applications.

Built Like A Tank - Raytheon Technology built the ELCAN for the warfighters in the field as tough as their aerospace defense weapon systems to win fights. It survives drop, kick, bump, shear and other physical abuses to retain zero.

Dual Role Missions - Shoot like a red dot on 1X with generous eye box and 4X for Target ID, all in one package

1-4X Instantly -  Skip 2X and 3X that shooters don't need anyway. Just flip the magnification between 1X and 4X prism scopes like a switch.

BDC Reticle - Calibrated for the NATO 5.56 up to effective 1000 yards (100 yd zero) with fast ranging scale to estimate target distance without a rangefinder

Clear Glass & Large FOV - On 4X feels like looking at the target on a 50" TV through the scope right in front of the eye.
