With all the talk about a sudden surge in interest of the LPVO, I haven’t seen the mention of back up iron sights with the LPVO. Can they co witness with the optic? I currently have an Eotech 518 and use the Magpul back up iron sights, but if I were to change to an LPVO, would the back up irons be necessary? Or is an offset red dot a better idea?
They scope is usually too long for a rear sight to flip up. I doubt it would work, but there’s no set up I’ve seen that would allow it to be tested. As far as necessary? That all depends on intended use. Maybe a qd mount and a flip up rear under the scope.
I personally don’t like LPVOs at all and would never have one for serious use. It’s a “shit or get of the fence” selection to me.
You can only co-witness with an RDS or HWS, LPVOs and prismatic sights cannot co-witness.
Whether or not BUIS are necessary depends entirely on your risk assessment. I personally think BUIS are necessary on all of my guns; for some folks and their uses, they may feel otherwise, and I would not necessarily disagree with them. I do not use QD mounts for my LPVOs, so I have offset BUIS (along with RDSes at 1200).
Is there really a sudden surge of interest in LPVOs based off of a single video that doesn’t even really showcase the strengths of an LPVO (is it even proven that an LPVO was used to take the shots, rather than an offset RDS)? If so, that’s hilariously pathetic.
Thanks, markm what sight system do you use with your rifle?
Yea, I agree, however it seems to be the interest of a lot of folks now, albeit over just one incident, and it appears that he was actually sighting with an offset red dot when taking the shot.
Etched reticle optics and a buis?
No, you can but you need a qd mount and co witness is a never.
Just forget about it and hope your optic isn’t total crap
My .308 AR is the only one with BUIS.
Don’t always need or want to use a scope so it’s on a QD mount.
My other mounts are regular ol’ cross bolts.
Thanks guys. It was just a question I had. Thanks for your responses.
The best optics in the world are still liable to condensate in certain weather conditions.
If a scope fails you may not be able to see through it, so either a quick detach mount to access the iron sights or offset sights. The latter being faster while the former being more robust if a FSP.
A fixed power scope plus an offset red dot may be lighter than a LPVO + BUIS. You would only have one unmagnified sight but occluded eye sighting could be used if the scope is daylight illuminated and that method works for you.
For me my shots are more likely much further out and I’ve always put scopes in place with LaRue mounts and BUIS. In the event a scope broke, has never happened before, I’d take the scope off and flip up irons.
And in the heat of the moment you will be point shooting because no one is going to wait while you take off your optic and deploy your back up sights.
They can most certainly wait if you make them wait as part of your pre-planning and the situation allows for it. If you’re deploying from an air conditioned vehicle to do a search of a premise in a very hot and humid environment, you definitely have time to flip up some offset sights. If you’ve been in and out between the extreme cold and heated buildings, and the condensation has iced over your optic, you’ll have time to remove a QD optic and revert back to irons.
I don’t know why everyone pretends like your optic will go down in the middle of a firefight. Unless you keep a backup optic on hand and have constant, easy access to range where you can zero it from, it’s far more likely something will happen to the optic at some point (or you move it) and then you just don’t have a usable gun until you get a new/repaired optic and zero it. Unless you have BUIS. That’s why I have them.
IDGAF about losing my optic during a gunfight and needing to suddenly rip it off then transition to BUIS.

I know scopes can be quite tough but a drop on concrete is still a concern, isn’t it?
The best back up “iron sight” for use with a LPVO is a MRDS. That said here are a couple older threads on the subject…

or taking a round.
Being the comfort-loving American that I am, I am revisiting offset irons for use with scopes. My assumption is that condensation coming in/out of air conditioning is more likely to cause a problem than dropping the rifle; an offset RDS will be nearly as useless.
Sure, but I am saying the likelihood of the event. As in, I’m far more likely to swap optics and not get a chance to re-zero for a while than I am to break my razor while actively in a firefight.

Seems like a lot of people who carry guns for a living are using LPVOs theses days, and many, (myself included) run offset irons or an offset RDS at 45 as a secondary sighting system. That’s probably the quickest/easiest option for a backup, as you don’t need to take the scope off.
