    Great 3 gun offset sights

    I had been looking for a great option for offset sights on my 3 gun rifle and stumbled upon these. I will admit I upgraded them with a fiber optic front sight post which is amazing. The sights are well made and quite durable trust me I chuck my guns in the dump barrels harder than you would expect sometimes. It took a while to want to do this review, I had to know if they would hold up to the abuse that we put them through. I can say that I don't think you can get a better more durable set of offset iron sights at this price point. My only complaint if you could even call it that is the front sight came and the finish on the mount was a bit messed up but it in no way affects the durability or strength of these. My competition guns are not show pieces as seen by how they get thrown around so this didn't bother me in anyway. Hopefully this helps someone who was like me trying to compare and find the best option, in my opinion you will be completely satisfied and glad you got these. I will try to add pictures later if possible.

    Thank you for such detailed feedback, Ron! We're glad to hear that you're satisfied with your BUIS. We really try our best to deliver high quality products that won't break the bank. -- LM
    Installed but not used yet

    Shipped and received timely. Threads on inside of rear sight were somewhat stripped so I had to replace rear mounting screw with a longer one. Once replaced, mounting was solid. Otherwise seem to adjust fine. Looking forward to sighting in at the range soon.

    My gun is done

    I have purchased the red dot, the magpul grip and the co-witness sights all from AT3 for my brand new Keltec KDB .556. It looks bad A$$ now it is time to go to the range and sight them in.

    Red dot and mag

    These are a great setup perfect with 45 offset irons.

    Setting up the offset sights

    When I received the sights and installed them, I realized my gas-block mounting point for the front sight was on a lower plane than the rear receiver-mount rail. So...I picked up a Tru-glo riser mount and all is good now. This is my first AR build and it's awesome. Anderson upper, 22" heavy fluted barrel 1:8 twist, repurposed my Delton lower, added BCM fire control group, Fail Zero BCG, Magpul butt stock, Vortex scope mount with a Nikon BDC long range hunting reticle scope. Man is it a tad driving, fun to shoot gun. And, the transition form scope to the offset AT3 Tacticle BUIS is smooth!
