Last nite I went on a drive to pick up a EOtech 512 slightly used.
I inspected it carefully to make sure its genuine (A how-to is stickied in Gear Talk subforum)
The 2 perennial rivals, what I call ” cheapest of the professional grade” ones are the AIMPOINT PRO and the EOtech512/517.
(A short review for those new to electrooptics:)
The Aimpoint PRO , is rugged, looks great and has 50,000 of battery life on one some watch battery.
Heck carry a spare and you basically have a lifetime of shooting with you.
it works of LED technology thats why its so power efficient.
A lot of guys dont even bother to shut them off.
The EOtech 512 need 2 AA batteries which last about 1000 hrs IF you use the best AA batterys money can buy.. the energizer Ultra Lithium. So this system uses bigger/hevaier batteries and needs ot replace them more often.
And the sight doesnt look as cool as the Aimpoint POR>
Why would anyone want it?
Simple Visual performance.
The Holographic weapons sight uses a reticle that is projected by lasters onto the glas in front of you. It is 100% paralax free at all times (unlike the Aimpoint which is only 90% paralax free).
The reticle with a small 1 MOA dot surrounded by a graduated circle makes for both faster acquisition at short ranges and more fine shooting using the 1 MOA dot instead of the AIMpoints 2 or even 4 MOA dot.
So When I got this exra ET 512 I took off my AIMpoint PRO off my LWRC M6. The Aimpoint then got mounted on another gun.
So I had to zero in two rifles tonite.
The zeros were quick and uneventful but it was fun to use the EOtech again.
