| Im a about to purchase a EOTECH 550 seris model, do I need an optical mount or does it come ready to mount on flat top? What are the differences between the difference between more expensive models to the slightly cheaper models? Just battery and night vision compatablility? |
Eotech's come with an internal mount that mounts directly onto flattops. u are also correct about the price differences in models |
|
Yes. All EOTech come ready to mount right to the rail. Short rule of thumb: 51x = Civvie. No Night Vision. Not warrantied for more than 10feet of water, etc. 55x = Military Grade. Night Vision. 66ft. submersible (I think). 511/551 = N Cell. Standard Mount 512/552 = AA Cell. Standard Mount 553 = CR123 Cell. Dual ARMS mount 555 = AA Cell. Dual ARMS mount 516/556 = CR123. Raised Standard Mount 557 = AA Cell. Raised Standard Mount. 62gr M4 ballistic reticle There are a few other colors, reticles, etc. but these are the basics. |

I found this to be a handy little chart. -Chris http://photos.imageevent.com/smglee/cltactical/huge/EOT-workchart.jpg |
I have, it's a troubling thing when your PAQ4 goes down due to a pressure switch going tits up and you can't remove the laser to flip out the control lever (good thing it was only training). Also mounting the NODs behind or in front of the sight during a long OP. But then again thats just my experience. But if all you are going to do is shoot paper then this really isn't much of a issue. |

Personally, I wouldn't waste my money on any mount. The OEM moun t system is great and can be unscrewed wit a coin. I got the 552 but wish I would have saved my $$$ and got the 512 instead. It is a great sight, but NV? I should have just built an IR laser system when/if I can ever afford NV. |

I have aimpoint and eotech 551 I went with the NV model 551 because I didnt like the 11 like SCREW HOLES ALL OVER IT and only good to 10ft of water so I went with the NV model 551 If I run DURACELL N it will run 100% with no trouble But I had trouble useing ENERGIZERS 3 times I found it DEAD with New batts install I wish I got the model with 123battery type I think its a 553 model I also like mine mounted as is on my LMT M4 14.5 FLAT TOP |
..ahem!  Works phenomenally well too, FWIW. A lot easier to aim with the EO reticle at long range than the IR laser. |
Damn, there goes my deep sea hunting safari, and I hope that any boating accidents happen in shallow water.

? it's been my experience that cco's/aimpoints have WAY shorter battery life than eotechs. and one more question, everyone here(ar15.com) swears by aimpoints, but all of my nco's say that CCO's ARE GARBAGE. anyone care to chip in?? |
are you really going to go diving 10 feet underwater before you go to the paper target range??? NO. as long as it is waterproof enough to keep out the rain or an accidental drop in a mud puddle YOU ARE FINE. |
551 eotech - 200 hours 553 eotech - 1100 hours M2 aimpoint - 10,000 hours M3 aimpoint - 50,000 hours M4 aimpoint - 80,000 hours Even if you look at an older M2, probably the cco you're referring to, it was rated 10,000 hours on a med setting. Even assuming the max setting might cut it down to even 25% of that, it's still 2500 hours and eotechs with cr123s or lithium AAs are rated at 1100. I like things about the eotechs, especially the ret, but I'm selling my 551 in favor of an M3. The last set of n-cells I put in had the unit flashing right away. So I put in new batteries and I don't even know if I could trust the thing to last a week of heavy use if I needed it to. I'll be able to leave the M3 on for years. I know it's not 'fair' to compare the battery life of the weakest eotech with the much more expensive M3. If I would have gotten another eotech, it would have been the 516 or 553 probably, and I VERY nearly did go that route. Either should be a very good optic. I may even get this aimpoint and hate it, who knows. I will forever steer clear of the 5x1 models though. |
the specs might say that, but i have personally seen aimpoint batteries go bad just from leaving them on OVERNIGHT, which is definately less than 80,000 hours if i did my math correctly. |
Then I'd say something was just seriously wrong with whatever unit/s did that, since no one else has reported such problems and people often leave them on for months/years. |

The Eotech, if turned on with the ^ button, will turn on and stay on for 8 hours, then turn off automatically. If turned on with the v button, it stays on 4 hours, then turns off automatically. If it is killing your batteries there is something wrong with it. Simply box it up and send it in for repair. They'll fix it. |

In addition to what A_Free_Man posted the EOTech shut off time will reset anytime you adjust the brightness. So if you adjust the brightness in that 4-8 hour period your shut off timer will move up. The auto shut off will only be an issue if you never adjust your brightness settings. At least for me, I find that I've always adjusted my brightness sometime within 8 hours so I've never had a auto-shut off issue. |
i'm not trying to be an @$$hole here man, but you are going to be disappointed! go to iraq with an aimpoint and ONE set of batteries, i GUARANTEE YOU WOULDN'T!!! on a medium setting YOU CAN NOT LEAVE AN AIMPOINT ON FOR MONTHS/YEARS. I PROMISE. |
I've heard the 10,000 hours for the M2 is not always the case over there, maybe the heat has something to do with it? Seems most Aimpoints that get left on in the comfort of North American safes live up to these 10,000, 20,000 hours claims  Or maybe the batteries that Aimpoint (the company) ships the Aimpoints with are better than the issued ones? |
