UTG Releases 3.9″ Reflex Dot Sights

Leapers’ UTG brand has announced the release of new low-cost reflex sight. The new sights, dubbed the “3.9′” (UTG does not publish why its named after a length, I can only suppose its 3.9 inches long) feature a fully adjustable green or red dot reticle offered in either just a dot or a circle dot.

The optics are a forward-set glass architecture, similar to many handgun dot sights. The emitter is buried in the rear, projected up onto the primary glass sitting at the front of the optic. UTG states they have reinforced windage and elevation adjustment, but for extra measure, an armor cover is included with the optic.

Available reticles are split into two options, a 4 MOA dot model and a 4 MOA encircled by a 58 MOA ring model. Both feature the full red and green illumination with fine-tunable brightness settings. The reticles are set at the absolute co-witness level for iron sight lovers.

Mounting is via a single Picatinny rail adapter. Construction is over “aircraft grade aluminum” which is the typical hard-coat black anodized. The optic is “Built on True Strength Platform, Shockproof, Fogproof, and Rainproof.”

Retail pricing for both the dot and circle-dot model is set a hair under $100, at $99.97. Street pricing will likely be slightly less, as there is not much room below $100 to go.

    UTG utter total garbage

    UTG Pro stuff is pretty good these days. Their AR rails are great. Their BUIS also work pretty well.

    Not sure about their optics, but it’s probably worth it to throw on a plinker.

    • Hellbilly

      Their optics are airsoft-grade. The only “plinker” a UTG optic will survive is one that shoots 6mm plastic BBs. Stick with Primary Arms and Vortex if you want low-cost optics.

        What a BS! I have an UTG Accushot 8-32X56 30mm Scope, AO, 36-color on my 300 Win Mag long range competition gun and it holds zero for about 500 hot loaded rounds. It also offers 100 moa of elevation adjustment range.

      • WhoKnows

        My first red dot was one of UTG’s gigantic red dots. I mounted it on my first AR and it actually worked pretty well – held zero and made it through 10+ range visits. I decided to upgrade because it was huge and heavy – I guess that is why it held up.

        I later put it on a 1022 for a while where it was also more than adequate.

        That said, the puzzling thing about this unit is the 4 MOA dot. That’s disappointing for my purposes and the reason I won’t be interested in these.

      I agree, the UTG Pro stuff is shockingly decent. Their slim line free float rails have been my go-to for my ARs since I found them. I’ve also used some of their stuff that has left me less than impressed. On that note, I think I’ll keep an eye out for reviews on this optic and see how it holds up. If it falls in with the Pro line in terms of quality, I’ll probably pick one up.

        Coming to Amazon shortly I’ll bet….get to find out then
        Edit: + 1 on their rails…

  • Ευστάθιος Παλαιολόγος

    Ι have seen, and occasionally used, a very similar-identical optic, from a german company called Falke.
    From the use of it I kept two things. One, sometimes it has difficulty with the On/Off button. Very annoying…
    Second, from the emitter to the glass there’s empty space which leads to obstacles (dirt, mud, rain etc) getting between and disrupting the projection of the dot
