EOTech EXPS3 HWS - Best Overall

daniel defense m4a1 eotech exps3 fde

The EOTech EXPS 3 is the best operator grade holographic sight to go with the M4A1. Many military and LE units are currently using. It's combat proven, good aesthetics and has great CQB aiming performance.

Best Passive Aiming Performance - Large window allows the shooter to easily acquire the target with both eyes open. This is extremely helpful while shooting on the move, over barricade and around corners.

CQB Holdover - Use the bottom of the 68 MOA ring for fast close range holdover to compensate CQB sight over bore offset.

Fast Target Ranging - Range a 5'8" tall human size target inside the 68 MOA reticle to quickly estimate relative target distance. In addition, use a magnifier behind the optic to engage up to 600 yards

Raised Height - The sight already sits at 1/3rd co-witness height for better cheek position for most AR15 shooters

  • Magnification: 1X
  • Objective Lens: 30 X 23 mm
  • Eye Relief: Unlimited
  • Reticle Type: 68 MOA Ring + 2 MOA Center Dot
  • Color: Black or FDE

Holosun 510C - Best For The Money

daniel defense m4a1 holosun 510c

Why people love this one - Holosun 510C is a great entry level red dot sight that is very well made for most shooting applications without breaking the bank. On top of that, the 510C offers an unique look among other optics on the market.

3 Reticle Choices - Cycle through simple point and shoot dot or with a 65 MOA holdover for distance shooting.

Fast Target Acquisiton - Large CQB 65 MOA use for fast target acquisition and range estimation.

Solar Fail Safe - Solar panel extends the battery life longer to keep you in the fight longer even when the battery dies

Quick Detach - Mount and de-mount the optic without any tools in the field. QD lever locking is mechanism built in so it never just unhooks randomly on its own in the field

You’ll save a ton of money for other accessories. 

  • Magnification: 1X
  • Objective Lens: 32 X 23 mm
  • Eye Relief: Unlimited

Aimpoint Micro - Best Durability

daniel defense m4a1 aimpoint micro red dot

Why Pros Use Aimpoint Micro - Aimpoint Micro is the best red dot sight on the market. It's the optic that sets the benchmark for every other small size red dots out there. Get this optic to make your M4A1 as operator grade as possible.

Point & Shoot - Shoot CQB targets fast with both eyes open even in improvised shooting positions. The window maybe small than EOTECH EXPS, but wider situational awareness

See Through Flip Covers - Just like the Aimpoint Pro, it protects the optic from dust, and no need to flip up the lens covers before aiming

Built Like A Tank - 7075 T6 aluminum to handle battle stress. Survives hard drops, holds zero and even near miss explosions

Simple 2 MOA Dot - Uncluttered POV for precise dot aiming at night & doesn't obscure the target like the 68 MOA EOTECH ring reticle (See more 2 MOA red dot sights here)

Ton Of Mounts Available - Uses any aftermarket Aimpoint Micro mounts you like with various height options

  • Magnification: 1X
  • Objective Lens: 20mm
  • Eye Relief: Unlimited
  • Reticle Type: 2 MOA
  • Battery: CR2032
  • Turret : 0.5 MOA / Click
  • Length: 2.44 inches
  • Weight: 3.74 oz

Vortex Spitfire AR - Best For Astigmatism 

daniel defense m4a1 vortex spitfire ar

The Vortex Spitfire is by far the best for shooters with astigmatism, open division shooting competition, and for a truck rifle setup.

Illuminated DRT Reticle - See reticle in low light conditions like a red dot without worry about the battery life or the reticle disappearing.

Perfect For Astigmatism - See glass etched reticle clearly even if you have astigmatism (Not the same as looking at a dot reflected on the lens)

Better Reticle Centering -  Eye box constraint forces the shooter to have consistent cheek position for precise long-distance shots up to 700 yards on 1X by reducing parallax offset

Works Without Battery  - The glass etched reticle is always there even without battery power. Use illuminated reticle or non illuminated reticle

  • Magnification: 1X
  • Objective Lens: 25mm
  • Eye Relief: 3.8"
  • Reticle Type: DRT MOA
  • Battery: AAA
  • Turret : 0.5 MOA / Click
  • Length: 4.3 inches
  • Weight: 11.2 oz

Leupold Mark 6 1-6X20 - Best For Distance Shooting


daniel defense m4a1 lpvo

The Leupold Mark 6 LPVO is the best 1-6X scope for this American made M4A1.  The first focal plane reticle is much more accurate for target PID at longer distances.

Premium Grade Glass  - Super crisp edge to edge glass clarity with minimum abrasion or bend (Better 1X). This is an unmatched light transmission performance to outperform in the most challenging lighting conditions like other high end 34mm scopes

5.56 C - Calibrated 5.56 BDC reticle combined with vertical auto ranging scale to quickly estimate known target size distance & moving target holdover to hit targets accurately

Fast 1 - 6X Transition - Very smooth magnification ring dial without any stiffness. Also accepts lever for better grip (Sold separately)

Zero Stop Locking Turrets - Never get lost or inadvertently adjust the turret to throw off the zero

Super Lightweight - 4 lbs lighter (~19% weight reduction) than the popular Vortex Razor & NightForce ATACR

m6c1 reticle
  • Magnification: 1-6X
  • Objective Lens: 20mm
  • Focal Plane: First Focal Plane
  • Eye Relief: 3.7"

Vortex Micro 3X Magnifier - Extends Range

q? encoding=UTF8&ASIN=B07WVXMXTS&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=rugerar556 20&language=en USir?t=rugerar556 20&language=en US&l=li3&o=1&a=B07WVXMXTS

The Vortex Micro 3X enables your Daniel Defense M4A1 to see targets much further away without getting into an LPVO.

Fast Sight Transition - Go between 1X and 3X in no time for better target acquisition

Much More Compact - Recommend using this for users who like mounting their red dots slightly more towards the rear to optimize eye relief distance

Better Zero - Greater degree of precision +/- 0.2 MOA on 3X than 1X when zeroing the red dot. Very helpful when zeroing a dot at night

Quick Detach - Mount & demount the magnifier off without any special tools
