Best M&P 15 Scopes

Holosun 510C - Best Overall

Why use this optic - If you are new to AR15s, the Holosun 510C is the best entry level M&P 15 red dot scope. For beginner this is a great starting point before upgrading to a EOTECH without spending $780.

Large Field Of View – Instantly place the dot on the target with unobstructed field of view while shooting on the move or transitioning with both eyes open

Extended battery life –  Solar Failsafe system keeps the reticle alive even if the 50k hours battery life runs out

Cycle through them by pressing "-" for 3 secs

2 MOA Dot + 65 MOA Ring - Use 2 MOA dot for unobscured precise aiming, and 65 MOA serves as range estimation & big enough for fast sight acquisition.

Interestingly, I find the 65 MOA ring helps for users with astigmatism without the center dot in the middle. It's a subtle thing that shooters can learn to appreciate for close up shooting

Unlimited Eyebox - Shoot around corners, barricade without the eye box restriction for fast transition

Vortex Spitefire 1X Prism Scope - Best For Astigmatism

Why Use A Prism Scope? This is by far the best for shooters with astigmatism, open division shooting competition and use as a truck rifle setup without worry about the battery life or the reticle disappearing. 

Works For Astigmatism - See reticle clearly almost like a pair of corrected lens. No blurry reticle or image for precise aiming

Better Reticle Centering -  Eye box constraint forces the shooter to have consistent cheek position for precise long distance shots by reducing parallax offset

Works For Crossed Eye Dominance - Use tall mount to tilt the gun to aim for crossed eye dominant shooters

Why Use The Aimpoint Patrol - The Aimpoint Comp series optics is by far the best tube style carbine red dot sights on the market under $480. It's as good as Aimpoint COMP series minus couple mil-spec features, but it's as rock solid as every other high end optics.

Precise Aiming Reticle - 2 MOA dot is fast to pick up and precise enough for accurate target engagement at all distances up to 200 yards.

Always Ready & Always On - The sight runs on one single 3V type 2L76 or DL1/3N battery that lasts over 3 years. It's always on without fumbling with brightness dial before use.
