    First-time Eotech owner: What do I need to know?

    It's time for another case of "The Newb Asking For The Hive Mind's Wisdom." Bear in mind I have almost zero experience with optics (frankly, almost all my experience is iron sights regardless of platform), and I recently got made a too-good-to-pass-up offer on an Eotech 552 with the laser (single beam, not IR-capable DBAL) add-on, so I need to ask for you guys to give me an "Eotech Boot Camp."

    1. What are the minimum add-ons and spare parts I should get ASAP? I already have a lens cover and QD adapter from GG&G on the way, and I found a compatible tape-switch on eBay. I know spare terminals/contacts and springs for the battery box are a good idea.

    2. Are there any special tips and tricks not mentioned in the manual that I should know about?

    3. Anything else not covered in the above two?

    Honesty the stuff you have coming in sounds unnecessary to me, though I donít know what you mean about the laser. I had the covers on my 512 when it was mounted on a paintball gun in 10th grade. Never really saw a need for them when I was old enough to start shooting. The battery contacts can be a PITA, Iíd hope they have that fixed by now though. My 553 had the issue years ago IIRC, pretty sure I sent it in and never had another problem.

    Iím waiting for someone to come in here and proudly declare that youíll need spare batteries.

    Thanks, Wake. Already have a nice brace of Energizer Lithiums for a start; the laser I have is the discontinued LBC.
    https://www.eotechinc.com/holographi...er-battery-cap (as opposed to LBC2, which has both visible and IR laser assemblies)

    Covers may not be necessary, but as a fumble-fingers who invariably ends up grabbing my glasses by the lenses when I'm trying for an earpiece they're a "peace of mind" investment and will hopefully help keep bag/case-crud away. (The GF picked GG&G's "Front Toward Enemy" version, we're trying to mimic a buddy Up North's setup when Canadians deployed to the Rockpile.) Hopefully they got it debugged well before mine even started on the factory floor, it has a March 2019 build date.

    For spare parts I'd say next time you're at Sams Club buy the biggest bulk pack of AA's you can find and then make sure you have a good set of back up irons to compensate for all that thermal drift you're about to experience.

    You can attach hand warmers to the optic to alleviate the thermal drift that was mentioned above.

    We run 552's and 512's at work. You must get lithium or use rechargeable batteries. The alkaline batteries always leak over time and ruin the electronics. I have a whole drawer of ruined Eotechs in the Armory. Also for cheap insurance if you can, store the rifle muzzle down. That way if the batteries somehow leak they will not leak into the sights. All of our rifles in the cruisers are muzzle up and all of the racks in the Districts hold the weapons muzzle up. When the batteries leak and the rifle is muzzle up the liquid gets in the body of the sight and ruins it. Our Eotech's are all between 8 to 15 years old. I ran Eneloops AA batteries and changed them every quarter and never had a problem. We issue low bidder GSA batteries and they corrode all the time. David

    Good to know, thanks--I'm running lithiums right now, though the optic isn't mounted on its host rifle; I'll mount it when the time comes to sight in and zero. I've been looking for USB-rechargeable AA's that'll work, but so far haven't been happy with any of the candidates' milliamp-hour ratings. On the other hand, half the runtime doesn't matter as much if I can recharge it...

    IMHO, what you need to know is you need to sell your Eotech and buy an Aimpoint T-2.

    It will be just fine. It is a good optic. Only thing you may want to look at getting is a riser mount to get the optic to a lower 1/3. YHM, LaRue and I think that MidWest Industries makes them. You would want one the normal lower 1/3 risers and not one of the stupid super tall ones.
    In no way do I make any money from anyone related to the firarms industry.
