L-3 EOTech: EXPS2 Holographic Red Dot Sight Review

[LAZY EYED SNIPER]

I've always been a fan of EOTechs and the new model EXPS2 definitely raises the bar over earlier models.

Offering true 2 eyes open shooting, a transversly mounted lithium 123 battery, and 7 mm raised base offering iron sight access, the new EXPS2 features easy to adjust side buttons and an adjustable, locking, quick detach lever for easy attachment and removal.

EXPS2 Features

■ Reticle is a 65MOA circle with 1 MOA aiming dot
■ Single transverse 123 battery to reduce sight length
■ Shortened base only requires at most 2 3/4 inch of rail space
■ Battery cap and latch are eliminated and replaced with a simple O-ring, tethered cap; better sealing is achieved
■ Battery compartment is now separated from the base to allow it to hover over the delta ring of the rifle
■ Average battery life at brightness level 12 is roughly 600 hours
■ Side buttons with an adjustable, locking, quick detach lever for easy attachment and removal

Reticle Options

■ EXPS2-0 - 65 MOA Ring w/ single 1 MOA Dot
■ EXPS2-2 - 65 MOA Ring w/ 2 MOA Dots

Re: L-3 EOTech: EXPS2 Review

I've had my 'Limited Edition' OPMOD (Optics Planet MODification) EXPS2-0 for a while now. I'm still not sure what Optics Planet changed other than adding their name to the side if the housing, but I couldn't ask for a better holographic red dot sight.

Here a couple pics of mine before mounting...





... and mounted on its host, my Spike's carbine...





The 7mm raised based allows for a perfect lower 1/3 co-witness with my BUIS and the 1 MOA dot is exceptionally clear. It makes a huge difference down range when the dot is only covering the bull instead of the entire target like larger 3 or 4 MOA dots. With no magnification, the EXPS2 exceeds all my expectations and allows me to put up groups that rival those made with my 3x power scopes.

I put 30 rounds of 55 gr. Federal XM193 into this target at 100yds...



I normally prefer less expensive options when it comes to optics, but for EOTech I make an exception. This EXPS2 is definitely worth the money. It's a great option for anyone looking to upgrade to a top notch holographic red dot sight.

Another awesome review my friend...!!

Thank you Sir!

Love the reviews you are putting up! Great photos as well.

The best part of the XPS series is the transverse battery design and using CR123 battery power.

I chose an EoTech XPS2-2 for my patrol rifle and could not be more pleased. I almost went with an Aimpoint PRO but I like the wider FOV the EoTech offers over the round FOV on an Aimpoint. It's like looking thru a Television Screen shape (EoTech) vs. a cardboard tube from a roll of paper towels (Aimpoint)! But to be fair, Aimpoint makes one helluva rugged optic that is practically bombproof.

I get exactly the same accuracy from mine with exactly the same ammo, L.E.S. and that 1-MOA dot is very easy to see in any light.

I'm sighted for ZERO @ 50 yards because it is rare to need range beyond that point, but with XM-193 I am +0.5" HI at 100 yards and -2.5" LO at 200 so it's basically a point blank rifle other than right up "in-your-face" close.

Good thread!

Thanks nitesite,

I love the transverse battery design as well. The shorter overall length allows for the addition of a magnifier, even with a short carbine rail...
