Re: School me on EOTechs
All other things being equal, I prefer Eotechs to any other comparable sight. Unfortunately, they are plagued by problems that seriously compromise their reliability. Recoil impulse damagin the battery connections is a big one. This is well documented if you do a search online, so I won't go into the boring details of every SOPMOD II and civilian 553 sight being recalled by L3.
I only use and recommend Aimpoints for reflex sights, period. Specifically, the T1 Micro, but they are all on the same level of performance so you won't go wrong with any of them. Eotech's abysmal customer service after L3's takeover is also a factor in that decision, considering I have had to return over 30 (yes, thirty) of their sights in the last 4 years.
Eotech's XPS line addresses the battery compartment as well as it gives a much smaller footprint, by using (1) CR123 battery oriented perpendicular to the bore. Still, the T1 has a battery life of 5 years versus 500 hours (likely less) for the XPS Eotech. This is a big factor for LEOs who may have their gun in their trunk for months without seeing it. Zero the Aimpoint, leave on setting 8, and it's G2G when you pick it up...in the year 2014. Something to be said for that, plus the cost of 123 or N cell batteries is in the hundreds to match what 1 CR2032 watch battery costs in a T1.
Just my $.02
