XS Sight XTI AR-15 Angle Mount Back-up Iron Sights

From the press release ….

XS® Sight Systems, in collaboration with Lone Star Armory, will introduce the XTITM (Xpress Threat InterdictionTM) AR-15 angle mount sights at the 2012 SHOT Show in Las Vegas, Nevada next week. The XTITM with XS® Express Standard Dot Tritium front, and White Stripe rear, are back-up iron sights designed for quick acquisition in CQB situations.
The result of extensive field testing the XTITM AR-15 Angle Mount prototypes were put through their paces by police firearms instructors, SWAT and patrol officers, as well as combat-seasoned former military professionals.
Here is what Police Firearms Instructor, Officer Michael Moore had to say about XS® Sight Systems’ New XTITM AR-15 Angle Mount Back-up Iron Sights.

“Magnified optics are great at distance but can be a hindrance when engaging threats at close range. The addition of your new sights to a weapon allows the officer to have the best of both worlds. They can engage a target with precision at distance and still be able to quickly engage a threat at close range. While testing these sights we had several instructors and officers engage targets at ranges from 7 yards to 50 yards and everyone was able to keep all rounds in the center of the target.

These new offset sights are another great innovation from your company and I have had to threaten bodily injury to be able to keep somebody from taking them off of my rifle.”

MSRP of $150.00

    A very wise man once said:
    “They put the sights on top for a reason.”

    • JMD

      These are intended as a secondary sighting system for competition rigs, where tilting the rifle to use a set of irons for close range targets can shave a few seconds compared to trying to engage targets at very close range with a magnified optic that’s mounted as a primary sighting method.

      That’s why the sights are not on the top. There’s a valid reason for this design, and AFAIK, they’re less expensive than other secondary sighting systems that are mounted at 45* like this for competition use.

      • Paul

        what’s the advantage over putting back-up sights on top of the optic? Longer sight base, I suppose…

      • 18D

        The advantage to this type of sighting system is that it allows you to have back up sights for close range targets when using a magnified optic on the top rail. When you use a magnified optic on the top rail you won’t be able to fold up the rear sight nor will you be able to use the back up sights through the magnified scope. The other problem is that with a magnified optic you can shoot at long range no problem, but your screwed for CQB. With these offset sights you can shoot at long range or shoot at short range very quickly. Best of both worlds.

      • Rangefinder

        Trijicon manufactures an ACOG with BUIS on top of the optic.

    • 18D

      How are you going to use those back up sights with a magnified optic genius? These sights serve two purposes. 1) They give you a back up sighting system when your using a magnified optic. 2) They give you a CQB sighting option where your magnified optic would not be efficient. This has been around for a long time now, where have you been at?

      • fw226

        I think he was noting that you could put a 0x red dot on top of a magnified optic, which would work. I think the benefit of these sights is they don’t cost as much as a red dot, and don’t run on batteries.

        Also, it’s really handy for us in fort worth to have XS just up the street. Maybe I can check these sights out next time I hit the range, for that matter.

      • Sian

        The problem with BUIS or RDS on top of an existing sight is it pretty much destroys your cheek weld and stance, where here you can just turn the gun 45 degrees and use a second, full length sight system.

        I’d still personally use an offset micro red dot instead of this, but I have bad eye dominance issues.

  • JStar

    Another wise man once said: “People who fear change will always be stuck in the past.”

  • Lance

    Looks good for a tactical match but a flip up sight is better and more accurate at longer ranges.

    • JMD

      Flipping up folding sights requires removing the primary sighting system, and irons are not used in three gun competitions for target engagement past 75 yards or so, typically. You and Burst both missed the point of this design.

      • JMD

        “…requires removing the primary sighting system…”

        Assuming the use of a magnified optic mounted so the ocular bell overhangs a folding rear sight. Just thought I should clarify that point.

    • 18D

      What’s your point Lance? These sights weren’t meant for long range. Not only that, but they would be equally useful for Military use and competition. How are you going to run a set of flip up’s when you’ve got a magnified optic mounted? Come on!

      • Jeff Smith

        I’m not sure, but I think some competitions REQUIRE you to engage some of the targets using iron sights. At least I think I read that somewhere.

      • Other Steve

        There is just no thinking any more. He’s rushing to see how many negative comments he can make.

        I see you trollin dirty.

    • Sian

      For a tactical match I’d just spend a little more and put a micro red dot in the same plane.

    • Lance

      Im saying for combat not competitions I did say they where awesome for competitions.

    • W

      flip up sights are most effective when using a aimpoint, eotech or other reflexive optic that does not hinder the sight picture of such sights.

      This is a innovative concept for those that use magnified optics. I have my Leupold mounted on one of my AR15’s, which utilizes a quick detachable mount from Larue. I can simply remove my optic if i need to and utilize the flip up sights i have mounted. With a system like this, i wouldn’t have to do this. They would be rather effective in close quarters combat.

      Of course, some ACOGs do have a crude “iron sight” and there are also mounts to incorporate a reflex sight above the magnified optic (there is a ACOG model with a reflexive sight mounted on it as well), though these are rather expensive.

  • JC

    The good thing about offset sights is that you can use them with a scope like the one in the picture. Flip up sights usually require you to remove the optic, but these just require a twist of the gun. The price isn’t too bad either – MSRP of $150 is probably about $120 in real world prices.

  • William C.

    A revolution in gangsta’ tech?

    I can understand the concept and utility behind these, but it isn’t my cup of tea. I’ll just stick with backup flip-up sights.

  • I like this setup for competition. Not bad pricing either.

  • Walker

    My ACOG is mounted on my carry handle, problem solved.

  • Tim

    He turned it sideways…KILLSHOT its a killshot!


  • YCL

    HAMR Scope does it better. Basically a Red Dot Sight mounted on top of a magnified scope.


    • vince

      Sure that Leupold HAMR is nice, but its $1,300 bucks! Those XS sights are only $150. I’ll take the XS ones in heart beat until I win the Lotto.
