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
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
Zero at 36 yard for the tightest 5" shot group (25 - 100 yards)
Unlimited Eyebox - Shoot around corners, barricade without the scope shadow getting in the way for fast transition
Mount on any M1913 Rail – Mount on M&P 15 and any other guns as long and the user can also manually tighten the clamp on out of spec rails

Easy To Pick Up Reticle - The 3 MOA reticle with unlimited eye relief provides fast target acquisition and get on target fast
Shockproof Construction - Built to withstand bumps, bangs, drops and the rough-and-tumble environment of the field.
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
Always Ready To Go - The glass etched reticle is always there without battery power during daylight use.
Illuminated DRT Reticle - See reticle in low light conditions without corrected lens like a red dot and even sharper image on 1X
Built In Eyepiece - Adjust diopter image clarity to the shooter's particular eye sight
5.56 BDC - Shoot up to 700 yards
Holosun 503GU - Best Lightweight Option
Why Use Holosun 503GU - This is the closest optic that assembles the feel and look of an Aimpoint Micro but at 1/3rd the price.
Recoil Proof - Hard anodized 6061 T6 aluminum housing that protects the optic internals from recoil and drops without losing zero on small bore rifles
The optic can retain zero perfect when handling 9mm, 40SW & 5.56mm recoil, so use this with confidence on your Smith Wesson AR15.
Versatile Reticle System - Cycle between a 2 MOA center dot and 65 MOA ring for faster CQB target acquisition and provide better holdover aiming reference
Accepts Aimpoint Mount - Use the same mount footprint as Aimpoint Micro. Different designs, heights and brands all work on the Holosun 503GU
Aimpoint Patrol - Best Durability
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.
Even Survives Fire - The hard anodized aerospace grade aluminum alloy housing protects the optic internals from hash combat environment and fire to keep the fight on!
Included QRP2 Mount - No extra money spent on buying mounts, It comes with a mount!
See Through Flip Covers - Shooter can still engage with both see through lens covers closed in an emergency situation. It protects from dust and doesn't hinder the shooter
If I had to choose between using an Aimpoint Micro or The Aimpoint Comp for a compact setup, I would choose the Aimpoint Patrol Optic for just under $480.
Vortex Viper PST Gen 2 1-6X - Best Mid Range Scope
Why Pick The Vortex Viper PST Gen 2 1-6X24 - Combining mid range and CQB capability into one package! This is by far the best low power variable scope for the M&P 15 for $800.
Fast 1-6X Transitions - Dialing between close range targets and mid range targets fast within half a second. Its an two-in-one aiming solution for any rifle applications.
Crystal Clear Sight Picture - Vortex glass gives excellent edge-to-edge image detailing for a minimum of glare distraction.
