Other than battery life, are there any performance differences between the Aimpoint Comp M2, M3 and M4s?
 
Re: Aimpoint M2, M3, M4s - differences??

This won't cover it all, but the main differences are in battery style and life. The M4 uses AA, which is nice, as they are common. Not worth the added price for the convenience, IMHO, as the batteries in all models last a ton anyway. The M3 has a longer rated battery life than the M2, but again, it's not that big a deal, particularly in a civilian application.

Other differences are some modest weight differences, as well as weather or not they come with the "ruggedized" rubber cover. I do also think there at MOA/size of dot differences within models. You'll have to read up before you select a particular one.
 
Re: Aimpoint M2, M3, M4s - differences??

the reason i don't like aimpoint because of those chinese clones. A lot of chinese aimpoint make a lot 100% like a real deal. I can't tell the differences

Re: Aimpoint M2, M3, M4s - differences??

I think I noticed a slightly less blue-ish hue to the image on the M3 vs. an M2. Something that was definitely noticeable between the old gen Comp XD and an M2.

So far I haven't really had any good reason to upgrade any of my old M2's and ML2's.
 
Re: Aimpoint M2, M3, M4s - differences??

The M3 is what I recommend. You have the option of the 2Moa Dot.......which I prefer. Plus it has a cool rubber cover to keep the optic from getting beat up. Batteries last a few more "years" over the M2....ha ha!! The M4 is nice, batteries last a life time in dog years, but is much more expensive than the M3.
My next red dot will be a M4s though.
 
Re: Aimpoint M2, M3, M4s - differences??

I used to be a Supervisor in the Trijicon ACOG Department. Now I'm a Military and Law Enforcement Equipment Retailer.

It basically comes down to differences in "Battery Life" and "Environmental Specs" (like water depth test).

The Aimpoint CompM4 and CompM4S are the only two that are truly "different" in several respects.

Aimpoint CompM4 / CompM4S
+ Uses AA batteries (instead of traditional Aimpoint batteries)
+ The Housing is Aircraft Grade Aluminum (instead of High Strength Polymer Plastic)
+ Comes with a Picatinny Rail Mount and Killflash (the other Aimpoint scopes come without mounts)
+ Comes with Bikini style lens covers (You can add the normal Aimpoint Flipup Lens Caps separately)

----------------------------

From another part in the thread:

Sometimes it is hard to figure out the "cheap chinese knockoff" vs "real authentic product" sites are. The best way is to see if they are a legitimate Aimpoint Dealer. You can do an Aimpoint Dealer search here:

http://www.aimpoint.com/where_to_buy

The bottom line is......you have to do the research about the businesses you deal with. Only buy from legitimate companies. Check to see if that business is a "dealer" of the product line you're buying.

If you have any other questions don't hesitate to ask. This forum doesn't have automatic notification so please use the contact email address listed in our profile.
 
Re: Aimpoint M2, M3, M4s - differences??

seriously your going to ask a question that can easily answered by going to the manufacturers website and doing some reading?
 
Re: Aimpoint M2, M3, M4s - differences??

Love my M4S and don't have any regrets whatsoever about not getting one of the micros. You can't go wrong with any Aimpoint: reliability is everything and Aimpoint has it in spades. I did replace the bikini covers with flip-ups. But now I have a greater appreciation for the bikini cover and think it is a good choice also.
 
Re: Aimpoint M2, M3, M4s - differences??

The main difference is the price. You can get an Aimpoint CompC3, which is just as good as the others for hundreds of dollars less.

Sorry but the M4s is not nearly the same as the C3. If you think that price is the only difference you need to go back and read up too.

I have the M4s. Should have bought the M4 instead. My friend has the C3 with the rubber boot cover and flip-ups. Shooting them side by side, there is no difference between the C3, M3, or my M4s.

Re: Aimpoint M2, M3, M4s - differences??

Paulo why would you rather have the M4 over the M4s? After comparing the 2 units for awhile I figured having the battery tube on the lower portion of the unit was a better configuration. Curious to hear your take on it--unless you meant one of the earlier models like the M3 or M2..

A couple of reasons.
1. If you use a magnifier, you will loose 1 rail of space because of the battery compartment being on the lower right hand side.
2. If you use a magnifier, the battery compartment on the lower right hand side is harder to get at to adjust/turn it on with the magnifier mounted.
3. I bought the Larue Medium mount and once installed, I was no longer able to adjust the Larue mount because the battery compartment got in the way. You will need very thin wrenches to adjust the Larue mount. I didn't have any problems when I had the high Larue mount.

And when I actually tried the M4 and the M4s side by side, I didn't notice much of a difference as far as field obstruction (I don't like to use field of view because guys will jump all over me telling me that red dots are supposed to be used with both eyes open).
 
Re: Aimpoint M2, M3, M4s - differences??

the battery compartment got in the way of the larue mount on the M4s??

I think you got the lever on the wrong side brother. The lever goes on the opposite side from the battery compartment.

umm, and yes red dots are both eye open optics.

I think the point of the M4s is not field obstruction, but to have a lower profile. less snagging, etc

Having said that love my M4s.

When I had the high mount it worked perfect, but it was too high for me. When I got the Medium Mount, the battery compartment sat right on top of the adjustment nut for the throw lever. It is a known issue. If you don't believe me, call LArue or order a Medium Mount for yourself.

I stand corrected. And yes I happen to own an M4s with a Larue mount.

I see no reason why not to use the tall mount compared to the medium. I have never heard someone say it's "too high" for them before. The rest of us just prefer either an absolute or lower 1/3 co witness. Not one or the other because one is too high or too low.

I go with the lower 1/3rd. End of problem

I'm still confused why the battery compartment on top of the throw lever is a problem? you have some big ass hot dog fingers or something?? Whole damn point of a co witness is not to have to remove the optic, so what is your rush?

The battery compartment doesn't sit on to of the throw lever, it sits on top of the adjustment nut. The throw lever is on the opposite side.

The high mount (lower 1/3) was too high for me because I'm short and have a short neck (or as my wife says, no neck. LOL). So for me a lower co-witness I had more of a chin weld than a cheek weld position and it was painful for me to shoot off a 30 round mag in the prone position because I had to lift up my neck so high. With the medium mount (regular co-witness), my head is in the upright position and I'm still able to get a cheek weld position. So for us vertically challenged folks, a medium mount is like a tall mount for the taller guys. Not everyone is 6'2" tall.
 
Re: Aimpoint M2, M3, M4s - differences??

yeah yeah, like I said, I stand corrected on the side the lever is on.

How much of a difference is there in the mount heights?

Maybe 1/2 inch??

Hey, rock on with what works for you.

My point was the different size mounts weren't developed to accomodate different height shooters. They were simply for those preferring an absolute or lower 1/3 co witness.
 
Re: Aimpoint M2, M3, M4s - differences??

I have 2 CompM4 models on 2 ARs and an M3 on my SOCOM. Besides the attributes mentioned above like the battery life, battery type and size. I like the M4 because there are more brightness settings and more NV settings if you will use that feature. Also I like the standard features like it's own mount, killflash and scope covers. But it is heavier than the M3 and I have Larue mounts for both but because of the battery and other features the M4 feels heavier. Also because it has it's own mount there are not a lot of mounting solutions. My M3 is hanging on a Leupold low 30 mm QD rings. You honestly can't go wrong with either but given the choice I would stay with my M4.
 
Re: Aimpoint M2, M3, M4s - differences??

Thanks guys, I found a deal on an M3 with LaRue mount, so I went for it.
