Advice Needed for EXPS3-0

[skydivr]

I've got both. I zeroed to 100 M, using the 25M zero targets created by a member of M4C, the confirmed. Worked Great. I keep extra batteries in the stock.

It's true, exps is lower 1/3 and can't be lowered to absolute cowitness.

Someone made that statement on AR15.com, so I researched it.

The description of EXPS scopes includes "7 mm raised base offering iron site access". That's not included in the XPS series description.

Sorry guys, I meant where'd you find the optic package. I haven't seen G33's in stock at all I don't think.

Brownells has G33s in stock.

I located it at Sport Optics www.sportoptics.com
Cost was $ 559.81. I was looking for a EXPS2, but couldn't find one in stock. Sport Optics had the EXPS3 for the same price.

XPS series is absolute co-witness, EXPS series is lower 1/3 co-witness.

Edited to correct to 600 hours.

Yes, which is why I advised not to forget using the 7mm spacer that comes with the G33 when using the EXPS series sights. As stated, not needed with the XPS series.

These were the 2 main reasons I bought the EXPS 3.0 instead of the XPS 3.0.

1. Lower 1/3 co witness
2. QD mount.

I suppose I could have saved some money and just bought the EXPS 2 but opted for the NV as well.

BTW the number designation indicates the number of buttons, ie NV button

3=NV capability
2=No NV capability

If you carefully read the tech specs on the Eotech web site, you'll see the built in 7mm riser on the EXPS series of sights. I prefer the wider field of vision on the Eotechs.

Zeroing has nothing to do with choice of sights. In large part it's personal preference. I zero all my sights at 50 yards. Typical ballistics would then have it also zero'd at 200 yards.

The EXPS series of sights are good sights. For some people, the battery life is big deal, but in my use it's not. If you're going to be engaging in extended firefights, or it's likely you'll have to roll out of the rack to grab your rifle because of enemies in the wire then battery can be an issue. Some people would extrapolate that to home defense issues if you feel the need to keep your rifle loaded and ready to go at your bedside at night. Not an issue for me. YMMV according to your planned use of the rifle.

600 hours is a pretty long time, and I think that between my grip and my iMod stock I have room to store something like five CR123 batteries. Additionally, you get plenty of warning. The reticle will flash at startup for a pretty long time before the sight goes TU.

Perhaps change that to "...is supposed to start flashing...."

Regardless of whether it's a 5-series or X-series optic, that aspect (like their published battery-life) is not consistent enough to depend upon it wholeheartedly. Moreso in the 5-series, but it's not the sure thing one'd hope it to be in any of them.

Better to maintain a "if there's any doubt, there is NO doubt" (thank you, Mr. DeNiro...) method in terms of battery replacement.

Basically, for anything one might see as an engineering shortfall on the X-series EOs, there's a procedural work-around to counter it.

I've never seen mine fail to flash, 5's or EX's, but I presume you have more experience in this arena and acknowledge your observation. Likewise, I've not experienced any inconvenience, and certainly not any danger, as a result of a 600-hour battery life (plus or minus), but I agree, I'm pretty liberal about switching them out.

[JSantoro]

Yeah, I draw that from a broad sample in terms of population AND time beating them up from ARs to HMGs. I'd not say "it don't work," just that they can go TU on batts without that indicator kicking on juuuuuust often enough that I don't think it deserves being counted upon, if that defines it enough.

Swapping out batts on an accellerated or just in case basis, as has been stated, makes up for this in particular and is the smart call in general for lots of reasons.
