Hera Arms CQS: Foldable reflex sight

hera_arms_cqs_01-tfb-tm

The new Hera CQS is a new reflex sight which features a foldable lens. The lens can fold down out of the way. Pressing the release latch flips the lens back into position (much like the current generation of BUIS).

This is a clever design. It would make a compelling alternative to the Docter Optic red dot sights which are sometimes used as backup or close quarters sights alongside another sight.

Docter Optic mounted on Trijicon ACOG

The CQS sight is made of aluminum. It runs off two volt lithium batteries and has a 4 MOA dot.

    Ooh, now that is clever. I’m afraid I’m not familiar with Hera, but if this sight works, then I’d be very interested in acquiring one. Any ideas on MSRP?

    C-More had a folding lens version of their red-dot sight back in the 1990s. Of course, it wasn’t this small.

  • Thomas

    This is vary interesting.. hmmm.. have to think about this.. thanks for posting..

  • Thomas

    Wish REMOV had a english version on his site..

    Let’s hope it’ll keep its zero. It’ll need to be a lot more precise than a foldable iron sight in this regard.

  • TCBA_Joe

    That’s pretty nifty. I wonder what they want for em?

    So are these being called BURDS vs BUIS? (Backup red-dot-sight)

  • Alden

    Any idea on price and availability/eta?

    • http://www.thefirearmblog.com Steve

      No idea on price.

  • Bill

    Nice concept – now make it rugid?

  • Crabula

    That is intensely badass! There really isn’t anything else to say.

  • Rusty Shackleford

    Anyone know the MSRP? This thing looks really cool!

  • Redchrome

    What’s the lens made of?

    If you’re intending to use this as a backup sight, it occurs to me that any incident severe enough to take out a primary optic, may damage this little thing as well unless it has a really sturdy cover.

    Interesting, but I’m not yet convinced it has lots of utility. Perhaps it would be good on a concealable SMG/SBR? (Which admittedly is one of the other things Hera Arms is known for — their Glock carbine conversion).

  • Nill

    I can see that lens getting soooooo scuffed up.

  • viper5552

    me likey concept! i also wonder about ruggedness, battery life, and price.

  • http://multigun.wordpress.com jbomultigun

    Hm. Would be neat to see a rig like that mounted on a pistol that would automatically deploy the sight when the gun is drawn from a holster.

  • Mike

    Very ciik.

    HERA is the company that makes the Glock carbine conversion that’s so bad-ass, you need a $200 tax stamp for it:

    It’s even been discussed on this blog:

  • D.Baker

    How awesome would something like that be on one of the new FNH FNP-45 Tactical pistols? (The slide is machined for a RDS) Much slicker than cutting out a hole in your holster for an RMR or similar.

    Of course, I don’t think anything designed to fold would fair well on a rapidly recoiling slide, unless it could solidly lock in the upright position. This looks a bit more like how the MBUS work (that is, will fold if too great a force occurs and pop back up).

  • Maigo

    I like the idea but I see two HUGE improvements.
    Make it out of steel
    A retractable cover. The lens is going to get so scuffed, it needs protection. If a cover were to just pop off, it’d be lost in 5 minutes, so it has to slide front or back. It doesn’t need to be big, just enough to cover the lens. To open it, you slide the cover over the battery compartment and the lens pops up and turns on.

  • Maigo

    Emailed them my idea. Seems they want to keep it super low profile and that the lens is replaceable

  • subase

    Nice idea.

    But it’s not a replacement for iron sights. Imagine if your optic is covered in mud or oil or who knows what else, that makes it almost impossible to see through. Your backup iron sights would be the only thing that could operate in that environment.

    It will serve as a backup to your optic if it happens to get smashed or damaged. But you should still have iron sights on your rifle.

    I also agree with the suggestion for a cover of some sort. But I think a person can easily tie a little piece of plastic around the sight, that can be easily ripped off when the sight is ready for use. That will keep it clean and protected. So no big deal.

    The worry about scratches and other items obscuring the front of the lens may be overstated. Remember that early Red Dot Sight designs, like the Singlepoint and Armson OEG, were not see-through. Instead, they merely reflected a red dot back to your eye. If you keep both eyes open, you can see your target and the red dot superimposed on each other. Early British Army testing of the Singlepoint showed that only a tiny percentage of shooters would not be able to make this work.

    Trijicon’s Glyn Bindon advertised this phenomenon as the Bindon Aiming Concept.
    http://www.trijicon.com/aiming.cfm

    The same effect can reportedly be achieved if you leave the front lens cap closed on an Aimpoint.

  • Redchrome

    Daniel Watters, your point is excellent. The technique does work; tho in my case the place my brain puts the aiming point is pretty far from most people’s. I think this is because I don’t have a strongly dominant eye. I can look through a scope with both eyes open, and see the crosshairs imposed on the target. However, if I close one eye the crosshairs move to another point. This happens no matter which eye I’m looking through the scope with.

    This (or my mild astigmatism) may also be why Eotech sights don’t work for me; the reticle looks huge and fuzzy.

  • Canthros

    It’s a neat idea and would be a swoovy piece of gear, but (other than fold) does it actually do anything that a Docter or similar sight doesn’t? It just seems like anything that would put your primary optic out of commission would probably destroy this, too, and most purposes served with a small RDS (e. g. side-mounted CQB optic) won’t require such a low profile.

    Nifty, though. There aren’t many iron sights that small.

    “It just seems like anything that would put your primary optic out of commission would probably destroy this, too”

    Maybe, but most primary optics stick out significantly. This is so low profile it likely not to be hit by something that would take out the primary optic – and anything that does hit it is likely to hit and possibly damage the weapon itself, too.

  • HeavenlySword

    Oh god, no fair!

    I had this idea about a year back, would be one of my products once I completed my degree and started a company…

  • Woody

    here’s an idea, just a hologram projector (a very small one).

  • Canthros

    Jake, if it’s that low-profile, I suspect most will want a riser to put the dot in a comfortably viewable position. At which point, it’s not going to be very low-profile.

    About the only uses I’ve heard suggested that sound suitable are mounting atop an ACOG (mostly because the ACOG is already pretty big) and on the slide of something like that FNP, as D. Baker suggested. The former’s probably only a marginal improvement over a Docter, and the latter may not work out, depending on the sight’s durability.

  • http://cursesfoiledagain2.wordpress.com Jake

    “Jake, if it’s that low-profile, I suspect most will want a riser to put the dot in a comfortably viewable position. At which point, it’s not going to be very low-profile.”

    I may be judging the scale wrong from the pictures, but it looks to me to be about the same profile (folded) as a folded rear back-up iron sight – combined with the pop-up aspect, that suggests that it’s meant for the same purpose. I can’t tell from these pictures if it pops up to about the same height as a BUIS or not, but I would expect it’s fairly close, which should make it usable without a riser for most people.

    I really don’t think it’s meant for normal use, just as an alternative to a BUIS (BURDS?).

  • Thomas

    I think this would work great on a Handguns.. SA, DA, Revolers.. Semi Auto`s like the Ruger .22 Pistol and Rifle..

  • Maigo

    I can’t see how it’d be useful if it was lower than standard sights
    Personally I’d love it on an offset rail on an SPR

  • Dan B.

    A damaged primary optic is not the only use for a sight like this. I use my ACOG in the school hallways, outside structures etc. and then transition to my Docter sight in close quarters. Remember guys, if a bullet takes out your primary optic, you probably won’t be around to need a back up sight…….your buddies might though when they split up your stuff.

  • Caleb

    Some rifles like the SU16 and benelli MR1 and some tactical shotguns have proprietary iron sights that are very low priofile but naturally come up to eye level beccause the stock is not in line with the barrel. I such cases a red dot sight like this might sit folded on the receiver rail without blocking the iron sight picture but be able to unfold and have a clear picture over the irons. I could also see it being used like a BUIS alternative with a quick detach primary optic.
