Is it high enough to see over front sight Expert Answer

Yes, the Trijicon ACOG 4x32 Scope w/ Illuminated Red Crosshair .223 Ballistic Reticle will sit high enough to see over an A2 front sight. However, I recommend using a flip down front sight.

Awesome optic by Smokewagonokc, October 6, 2018
Never thought I would spend this much on an optic. Once I saw my buddies and how clear it was I had to have one. The hogs better look out. I mounted it on my 6.8 SPC with a 12” barrel that I just built.

Very nice sight by Tai, February 15, 2019
I have this mounted on my ar15 for target shooting. The clarity of the lens is very nice. What I like the most is that the reticle illuminates via fiber optics and doesn't use batteries. I do not regret buying this sight at all!

Acog 6.8 spc by Eric Branstine, Verified Owner, June 22, 2020
This is by far the most expensive scope I have ever bought, that said it is well worth it! This thing is built like a tank. I have this on my 6.5 Grendel and can switch it out with my 6.8 spc with no real ballistic disadvantages. My only complaint, a...

Features of Trijicon ACOG 4x32mm BAC Rifle Scope - .223 / 5.56 BDC

  • Always On, Always Ready: Most ACOG models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.
  • Take Control: Several ACOG models are designed with a user-adjustable brightness setting powered by a single AA battery. The 3.5x35 LED and 4x32 LED models both offer six adjustable brightness settings.
  • Rugged, Reliable Housing Design: Fixed-power design allows for minimal moving parts to create a nearly indestructible sighting system.
  • "Both Eyes Open" Design: "Both eyes open" shooting using Trijicon's Bindon Aiming Concept (BAC) feature allows for improved situational awareness.
  • Outstanding Clarity: The quality of the glass and multi-coated lenses maximize light-gathering capabilities and clear field of view with zero distortion.
  • Exact Target Distances & Holds: Most ACOG models feature a bullet drop compensating and target-ranging reticle for decisive aiming.
  • Combat Proven: No other magnified optic has been used more in combat than the ACOG.
  • Shock-Resistant: Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.
  • Waterproof: Exceptional waterproof performance that exceeds military standards. Dry nitrogen-filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry-nitrogen filled housing that mitigates fogging.
