Dueck Defense Red Dot Back Up Sight Base

11379918_1720112211538224_829031430_n

Dueck Defense, makers of the RTS angle back up irons, has made their version of a red dot adapter plate for Glocks. Their RBU (Red Dot Back Up) sight base drifts in place of the rear sight on the Glock slide. The sight base is machined to accommodate the more common mini red dots like RMR, Leupold Deltapoint, Burris and JPoint.

The RBU sight base sets itself apart from other rear sight mounted red dot bases because it has integrated iron sights. The irons are fixed and provide a reference point for shooters in case their red dots go down. I had this issue the other day with my STI Steelmaster. My red dot died while shooting and I have no back up sight to reference so I was point shooting. I missed a bit. With the fixed RBU base irons you have a better idea where your gun shoots in relation to those irons and can make adjustments via kentucky windage to get those shots on target.

Here is a review by Practically Tactical.

 

I wonder if it would be possible to redesign the RBU to allow for factory Glock sights to be attached to the RBU? That way you could adjust the irons for elevation and windage. Also having a fiber front would be nice. But that would get more complicated and increase cost.

    Mounts in the dovetail – check.
    Has a 2.5″ sight radius – check.
    Adds even more height to to those stupid dovetail red dot mounts. – check
    Is it steel to increase slide weight?
    Or aluminum to ensure the threads strip out?
    That is one of the most worthless things I’ve seen in a while.
    Does it come with a sticker?

      Well, since it’s made by Duck Defense, at least you know it’ll be “patent pending” as well as priced at 5-10x more than its competitors.

    I’d have to agree with Spencerhut, this doesn’t look very useful to me. If you put a tall enough front sight on the pistol, just centering it in the malfunctioning window of the red dot like a big ghost ring would be faster and more accurate. Or just cut out a little front blade and rear sight out of cardboard and stick them to the front and back of your red dot with double-stick tape – same effect, for a total price of less than a penny!

    Isn’t this why you either get one of the pre equipped flocks with the mounting system, or just buy a new slide that’s cut for it. You’re already spending bank on the RDS so why not get a new slide and do it proper with a better co witness?

    • Orion Quach

      Because stupidity

    • I just looked up the price and it’s pretty much identical in cost to get the slide milled for the RMR as it is for this mount. You have to spend a bit extra for supressor height sights though.

      If you are running an issue gun, but your organization allows for swapping out sights, it would be benificial. Personally, not a fan of the perminantly attached sights though…If I got one I would mill off the rear and front and set up the front to take standard front sights, and either mill a dovetail for the rear, or attach the optional rear sight on the Deltapoint Pro

    Useless if the glass cracks, breaks,fogs, etc

    queck queck queck! the sound of an impending dueck attack.

    Not big on putting red dots period on a pistol. The constant and extreme reciprocation beats the hell out of them, regardless of the mount used if it slide mounted. They offer little to no benefit at close range, but they do increase hit rate at longer ranges. So what? It’s a pistol.
    This may change in the future, but now, it’s your money. Cue the “yeah, but… competition shooting.” If you can afford it, go for it.

      Yeah but… competition shooting.

    I’ve been looking at this so I can shoot Carry Optics division in USPSA without having to mill my slide. This or the Suarez mount just my be the ticket.

  • tazman66gt

    the ultra short sight radius makes me want to go out and buy one (sarcasm)

  • Treyh007

    Wow, not sure of the logic of a 2.5″ sight radius for competition…… They would probably be better off scraping the iron sights just having a red dot mount. I’ve had my G34 MOS for a few months now and even tho it’s not a tacticool custom milled slide, it works great! Had an extra Burris FF 3 laying around so I popped it on and its held zero for 700+ rounds so far. Might buy an RMR in the future but no reason to as of now, the G34 MOS with FF3 has ran excellent!

    • William Elliott

      its called “backup sights” for a reason.

  • Giolli Joker

    These should come with iron sights to be mounted on the side of the slide: gangsta style!
    Like the angled rails for short range sights on competition AR-15s.
    (sarcasm… and already seen them as internet joke, now waiting to see them as tactical accessory…)

  • iksnilol

    Well, the short sight radius improves aquisition… Though I doubt you’d see much accuracy, might as well remove the front entirely to decrease the sight aqusition time 😛

  • William Elliott

    HAH, I posted up before I saw your post
    too bad its only for the RMR. I’m considering a Deltapoint Pro
