Referenced Recoil Off Grid

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

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.


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.
