Holy Giant Optic Batman! Firefield Kemper XL

I found this optic while checking out some photos people posted of their Kel-Tec Sub2000. Before you ask, that Sub2000 is sporting the Red Lion Precision rail which allows it to index and rotate. Thus allowing the optic to move out of the way when folded.


The Kemper XL is made by Firefield. It does not seem to be listed on their website. But it is available on Amazon for under $100.

This optic looks ridiculous. Like a drive in theater screen LOL


Kemper 2

A customer actually bought one and put it on his FNH SCAR16S.

I got this thing 2 days earlier than expected, so kudos to the seller. It’s big, the field of view and eye relief are infinite, it’s durable. It’s easily adjustable and the sight glows bright red or green whether your environment is light or dark. I have it on my FN SCAR 16s (5.56), I’ve put over 100 rounds through my firearm with this thing on and it’s held zero and not moved an inch on top of my gun, and I have yet to have to tighten it on with a screwdriver. I’ve simply screwed and unscrewed it with my fingers for each use (of course that could be because of the low recoil of the SCAR.) The way red dot sights work are a light is turned on behind the glass which projects the sight, and the glass reflects the light back to you, giving you the image of the sight – which brings me to why I’m giving this 3 stars. The glass reflects more than just the light, in fact it reflects just about everything dark behind it. Because of this I found it difficult sometimes to distinguish between what was actually in front of me and what was just being reflected. I posted customer pictures 1,2, and 3, picture 1 shows the reflection issue.

Update: I had to return this sight, the reflection issue was too much for me to handle.

  • thedonn007

    I could see that thing breaking pretty easily.

  • Looks like a Chinese copy of one of the crew served weapon holo sights.

  • Ambassador Vader

    Why three stars? this optic allows you to operate While operating behind you. 2x the operation for the same price. Now if only they could incorporate mirrors to the left and right. 2x the operation is good but 4x the operation is optimally operational…….ugh

  • Petto

    LOL somebody liked DCL-120 field of viet , why not bro

  • KestrelBike

    We’re going to need a bigger bag.

  • stephen

    The pro version has windshield wipers… πŸ˜‰

  • Jeff Smith

    Doesn’t another manufacturer make a similar model? I remember seeing pictures of it mounted on an M2 or a M134.

    • J.T.

      BE Meyers DCL Series

      • Jeff Smith


      • Mr Mxyzptlk

        I believe that they are made by DI Optical (south Korean company) and used to be imported by BE Meyers. I don’t think they do any more, as DI Optical has a US subsidiary now who sell them direct.

  • ItalianAmerican

    HEY! I can FINALLY watch TV in my Kemper optics!!!

  • Joshua Knott

    2000 dollar rifle + 100 dollar Chinese optic= Legit a.f

  • AMX

    I… I want one.
    On my Glock.

    Stop judging me!

    • Nicholas C

      KC Eusebio had a Trijicon SRS on his Glock.

      • Ben

        and he never needed to go to the gym again.

    • El Duderino

      It might actually look good on a S&W X-frame or the .44 Hunter model.

  • gunsandrockets

    Now just make it out of bullet resistant material and voila! you have a face shield like a Bond Movie villain!

  • Evan

    Now why didn’t I think of duct-taping a magnifying glass to my rifle?!

    • Nicholas C

      Someone beat you to it.

      • M40

        Wow… this allows you to transform your gun into a VERY small game rifle (fleas, gnats, ants, etc). And if the rifle jams, you can just burn them up!

  • Richard

    Isn’t this supposed to go on heavy machine guns?

  • Polaritypictures Ken

    Reminds me of the Optics on the rifles used on Captain America Winder soldier. When they Assault the Ship.

    • Richard

      In the movie they used either one of these or a more expensive model on the AUG.

    • Mr Mxyzptlk

      I believe that one was a DI Optical DCL-110, it was portrayed as a sort of X-ray sight if I remember correctly. These sights (there are a few in the range of varying sizes) are intended for use on machine guns, and one actually appears in Civil War as well in a more practical use being fitted to a helicopter mounted FN MAG.

  • TheUnspoken

    The perfect red dot for the Mark 23 and Desert Eagle….

  • Ryfyle

    Now to put it on a pistol….

  • Giolli Joker

    If the sun is behind you and you run out of bullets you can still ignite your target!

    “it’s held zero and not moved an inch on top of my gun”
    It did not move 25.4mm, it’s solid… πŸ˜› πŸ™‚

  • UninfringedTech

    That might not be bad on my crossbow!

    • Keyser Soze

      Oh yeah thats actually a great idea

  • BrandonAKsALot

    Get on mine level comrade

    • gunsandrockets

      needs grenade launcher attached for triple-barreled goodness!

  • El Duderino

    Bipod on a 9mm…alrighty then.

    Paint the optic orange for some well-deserved Borderlands cosplay.

  • JSmath

    Welp, that’s in contention for most hideous firearm accessory I’ve ever seen.

    • Striker333

      Have you seen the picatinny rail tampon holder?

  • Gorilla Biscuit

    When you had SCAR $$ but you ripped your couch and had to hold it up with a 2×4. Then you go to China Town optics ………

  • Striker333

    I think I saw that on American Gladiators?

    • Striker333

      It was mounted on a tennis ball launcher though-

  • Drunk Possum

    Mount this mother on a 1911/2011 for the ultimate two eyes Open gun. In all seriousness, I’d actually be willing to give this thing a go just because it’s so damn big. I love watching TV!

  • MrEllis

    Two, please.

  • Weaponized_Hotdog

    Field of view at 100 yards? All the yards……

  • Greg W.

    You can check your own 6 without moving!!

  • Rollin Shultz

    I suppose you will get used to the reflection issue the same way you get used to ignoring your heads up display on the windshield when you drive until you want to see it.

  • ABeiruty

    If you want a large field of view with no obstructions what soever, get a green laser installed. Done the right way.

  • Boss

    Dose it have cable?

  • rick bennett

    glad you all are having a good time with this,but seriously for older people with diminishing eye sight this may be a good thing

  • Peyton Quinn

    Is everyone concerned about what a tool like firearm looks like? OK even I like the looks of some weapons, but dam good people you won’t care or be able to even think what you weapons looks like if you need it to save your life or protect your family.
