Eotech VS ACOG

[HK Dave]

From what i hear, new Eotechs were hardened to meet sopmod requirements to survive a much higher recoil pulse. It also seems L3 did something about thermal drift. I’d personally not hesitate to run one and for cqb, it and the Vortex UH-1 are probably the fastest on target optics currently around. IMO of course.

I just sold all 3 of my Eotechs 512. The short battery life was a major issue. Plus they just didn't feel right for me. I love the Acog and aimpoint.

Acogs are nice, but not a fan of the Eye Relief. As far as Eotech, Love em. Eye Relief and Parallax Free.

I have a cogs and Eotech. For my money, the Eotech is much faster for target acquisition.

Lots of options for ACOG’s. It’s not just TA31 that is available. For CQB, look at the TA44-C (1.5x). Super small and lightweight. Perfect for my lightweight AR-15. TA31 is great for target ID’ing with its wide FOV and beautiful view, but it sacrifices eye relief. TA11 is best all around at 3.5x, but it is the largest and heaviest of the options. TA33 is a good 3x for range and CQB but it has an extremely narrow FOV....like looking through a pipe, and it doesn’t feel like 3x.

If you want true CQB, Eotech is a good choice for that (and I’ve owned a 512 and an EXPS3.0) and the reticle is amazing, but both my samples exhibited eventual reticle disappearing around the edges. I’ve seen it in multiple samples, and read a ton of other people getting the same issue, which leads me to conclude it’s not an optic I would choose if my life depended on it. It’s fine for a range optic, or maybe a SWAT member when you know you’re going to engage.

But for those “bumps in the night”, even though it’s just a dot, I’d go with either a Trijicon MRO or an Aimpoint. Both are bulletproof, and the batteries last for years. I leave my MRO on mode 4, which is medium brightness, and it’s been a year and a half without a glitch. I expect it to last another 2 years before needing battery replacement.

As much as I like the Acog and run it with a RMR on my primary rifle, I recently found the negative of the shirt eye relief of the TA31. It never bothered me and with a offset-rear mount was fine with my cheekweld, never a issue for me regarding shooting. But I noticed recently my $100 Oakley shooting glasses scratched up in the middle and didn't know why. Then I noticed my second pair of Oakley's were also scratched up in the middle, while doing a run and gun I noticed during some positions shooting around baracades that the short eye relief TA31 was hitting my glasses. Maybe time to go back to my $20 shooting glasses when using the Acog.

Could always put something around the back too! Plasti dip and a q-tip?

[Rubes&Spike13]

Own both and a few varieties. Yes, if you want a eotech go for it. Yes you could add a red dot to the acog but if you want to factor weight and ergonomics in then a simple eotech or even a aimpoint will work for you. But try before you buy if you can. All down to preference.

Holding on center, with a 50/200 yard zero, I shoot steel silhouettes at Angeles out to 300 yards with my old Eotechs.

Kinda sucks their steel doesn't begin until 200 yards, unless you're shooting a PCC, so kind of hard to practice CQB shots with an AR at Angeles.

Haven't heard anyone in here mention magnified prisms. I have astigmatisms and nearsightedness, and a magnified prism with a diopter solves both problems. But is the FOV too limited for CQB?

I like the EOTech, but it is a donut of blur without my glasses on.

BTW, I just bought some new lithium AA rechargeables for my EOTech 512. That's right, lithium, 1.5v's. Haven't had time to test the charge life yet. These Tenavolts AA's go on sale for like half price regularly on Amazon.

Good thread.

I love my combo: EOTech EXPS3-2 backed you with an EOTech G33 Magnifier. At close-in, the two dots blend together. Pop up the magnifier, and those two vertical dots with the 65 MOA circle make a weirdly accurate distance targeting system.

[Kmai24]

Ta44 (1.5x16) with the ACSS reticle. That will fill all of the niche for the setup you’re going for.

I chose an EXPS2-0 for HD/SD, because the high visibility of the 65MOA reticle is hard to beat. The battery life, and the need to press a button to activate it are non-issues for me. If the batteries die, I can just use BUIS for 1/3 co-witness, or simply use the QD to detach. Also picked up the G33 since there's currently a $100 rebate from Eotech. This meets both my CQB/HD/SD and range/competition needs.

The Aimpoint PRO model is quite beefy, loaded with features, and is proven. Consider that as a cost effective option. Otherwise, the T2 series (T1 if you want) or any of the COMP variants will do you just fine.

I like the EOTechs and don't have an issue with battery life if you have a standard service interval, but consider astigmatism if you have it.

Holosons also seem to have proven themselves as of late. They have a variant with the ACSS reticle which would pair nicely with a magnifier.

That's actually a very good point. I own Aimpoint, Eotech, and Acog, and Eotech is my favorite recticle but even though I have 20/20 vision I have astigmatism unfortunately and it makes the Eotech looks like a fiery sun and the Aimpoint a shooting star. Acog due to its prism looks fine even with my astigmatism and is a big part of why I primarily use it. Without astigmatism I'd probably go back to a Eotech.
