Aimpoint Micro T-1 2MOA or 4MOA

[VoxVeritasVita]

Ok....getting ready to order a Aimpoint Micro T-1 from LaRue.

Which dot is better and why, 2 or 4 MOA?

Also decided on Tall (LT660) LaRue Mount
Allows a 1/3 cowitness with the Iron Sights. Any argument here?

Any help,advice and otherwise greatly appreciated!

I got the T1 in 2 moa. The smaller dot is easier to see on targets farther out and turning the brightness down making the dot seem even smaller, kinda needed if you ever put a magnifier behind it. The smaller dot also allows you turn up the brightness with out putting a huge fireball dot(it does blaze red on 12). It still gets big but not as big as 4 moa. I can't comment on the height you picked, think that along with dot moa is preference. I have absolute co-witness on mine.

I like absolute co-witness but everyone has their own take. Personally I think it makes it nice and easy to get everything lined up. I personally feel as though the reason for buis is to use when or if your optic isn't working. If that is the case, then it doesn't really matter but is simply personal preference.

Regarding the 2 or 4 moa dot, that would probably depend on whether you plan to shoot longer range (over 100 yards) or with a magnifier or not. If you plan to shoot distances greater than 100 yards or use a magnifier, then get a 2 moa dot. If you plan for shorter distances then get the 4 moa.

I personally would go with a 2 moa dot, with a 3x magnifier flip to the side la rue mount.

Personally, when I shoot to 100 yards I want a 4 MOA dot. at 15-25 yards, I don't care as much, 2 moa is fine, 8 MOA is fine. 16 gets to b a bit much at any distance.

Caveat: I'm not magnified at all. Just red dot. But 2moa is no good IMO for daylight shooting @ 1x @ 100 yards. at any brightness.

Personal opinion. Worth every penny you paid.


----------

The "secret" to shooting tight groups with a 4 MOA dot is to shoot the NRA standard 25 yard rapid fire pistol target. The 2 MOA dot is really hard to center in that target and group size suffers. The 4 MOA dot fits very nicely and makes it very easy to line up the dots concentric. Leads to potentially deceptively small groups. Far smaller than calgunners would lead you to believe.

Then for non NRA Target targets (bottles and steels) it's just easier to pick up the dot and go. When go-nogo accuracy is enough.

If your suggesting you "line up" buis & a T1 etc, you are doing it wrong. You look through the aimpoint, period. I can see my FSB through mine, it aint "co-witnessed" It's simply called that due to different heights. I have a Larue QD tall & an Aimpoint T1, I love it, get the 2MOA. You can turn it down to make the dot smaller for zeroing purposes.

I have both. I have a 4MOA Micro T1 on a LaRue 660 on an LMT M4 upper that sits on a Mega Zedu/Stag LPK lower. I also have a 2MOA micro T1 on a LaRue 660 mount on my Colt 6940 M4 so feel I can comment. I can think of no reason to buy the 4MOA over the 2MOA unless there was a big price delta. If the ability to pick up the dot fast is important, you can crank up either and let it bloom and get a bit bigger for fast acquisition, but if precision is required, you can never make the 4MOA dot smaller. Neither present a true dot if you look closely. Both have a bit of a tail from the main dot if you look closely, but the 2MOA allows you to resolve a smaller aiming point than the 4MOA. All are S/N verified as real Aimpoint devices.

I like the LaRue 660 as the optic is pretty comfortable and easy to acquire. I feel like going to a true co-witness might drop the line of sight low enough to make it harder to see, but that is speculative as I haven't tried it. The LaRue mounts have been very repeatable.

I have an Aimpoint 3X MAG that sits on the Colt, but has been tried with both and the flaws on the larger dot on the 4MOA are more apparent on the 4MOA T1. It is on the stock Aimpoint QD mount, but I have been looking at upgrading to the LaRue mount. It doesn't turn even the 2MOA T1 into a precision optic, but allows me to shoot smaller groups at 100 yards and continue to hit the steel repeatedly without too much trouble out to 300. The longer shots are more challenging with the 4MOA, but 200 yards is still pretty achievable.

I also have an Aimpoint 4MOA Micro R1, which is a silver version of a Micro H1 (not waterproof or NV compatible version of T1) mounted on an Ultimak rail on a stainless Mini 14 Ranch model and am very pleased with it. The lightweight Micro platform and compact form factor work nicely on the Mini14 mounted in a scout position.

The little Aimpoints are good stuff!

As an aside, if you get one, try and find a Kight's Armament (KAC) battery compartment cap (http://www.knightarmco.com/shop/inde...products_id=87) . It's much better than the stock cap as far as grabbing the knob to quickly change illumination settings, but also allows you to carry a spare CR2032 battery. One of the high points of the newer Aimpoint Micro line is their ability to run for a long time on a battery, but batteries will fail and having a spare on hand can never hurt.

[Press Check]

I have both 2moa and 4moa and see no difference at 50y and under. At 100y, I use an ACOG.

Valid points all across the board, though.

Thank you everyone........Aimpoint Micro T-1 2MOA/M4 Tall (LT660)QD Mount Combo ordered! Can't wait, have wanted this for awhile.

[teflondog]

The 2MOA was a good choice. If you adjust the brightness up, the dot will bloom into a 4MOA in case you ever need it.

Red State Tactical has a better price that Larue direct, and ready to ship as I post this.

This might belong in another post but since I also recently acuired a 2MOA Aimpoint T1 with Larue 660, my question is the mount and optic should be placed above the ejection port or slightly in front of it and why? Also if you can reference rail number if applicable. Im mounting mine on a DD M4A1 Mil Spec+. Thanks all.

I like to place mine as far forward on the upper receiver with out bridging the upper and hand rail. That way its as far forward away from face, and will keep the most constant zero. If put on handguard or bridged the guard could twist and your off zero.

@pureR00R thanks for the input.

[VoxVeritasVita]

......after a very long day at our range Saturday wand well over 500rds, I am very very pleased with the performance of the 2MOA Aimpoint T1 with Larue 660 mount on my Noveske GenII, Vltor upper, Geissele S3G, JP FMOS BCG, Noveske "Skinny Moe" barrel rifle. Absolutely my lightest rifle and the T1 rocks! Super-fast to get on target and performs flawlessly. We have many fantastic optics, and I am overwhelmed by how much I love the T-1....I want another one. Thanks again to everyone that helped with the decision.
