Customers say

Customers find these sights well-made with a heavy metal strong spring, easy to install without tools, and appreciate their clear sight picture and value for money. The functionality is positive, with one customer noting they work perfectly with their Spitfire Primze scope. The fit and ease of adjustment receive mixed feedback - while some say they fit beautifully and are easy to adjust, others find them very tight and the front sight hard to adjust. Several customers report issues with the front sight being crooked.

4 out of 5 stars
Wish I could review the actual product
Ordered these hoping to replace the older MBUS 2 sights on my rifle. Wasn’t super thrilled about the new deployment button style but did love the tool-less adjustment feature. Unfortunately, the first set I received was packaged in a bag stating they were MBUS 3 but were very clearly the original MBUS 2. No big deal, it’s happens, and Amazon was great as far as getting them returned and a new set shipped out the same day. The replacement set showed up the next day and my excitement fizzled as I opened the box and realized, yet again, they showed up packaged as MBUS 3’s but were very clearly 2’s. I’m not super confident this won’t happen again so I really don’t feel like sending them back just to get 2’s again. And after reading all the reviews about the deployment button being awkward to push, the sights not laying flush with the rifle, and the front sight posts falling off, I think I’ll just stick to the trusty MBUS 2’s I already have installed and keep this second set as a back up. Either that or just Install them on something else as the 2’s I have are nearly indestructible and I’ve never had any complaints about them. Just to be clear the single star is for the seller, not for the sights. I love the MBUS 2’s but wish I could have given the 3’s a shot (pun intended, lol). ***Editing this review from a single star to 4 stars as the seller did end up making things right in the end. Still didn’t get the set of sights I wanted but they did issue a refund for my purchase which is greatly appreciated***

    5.0 out of 5 stars Great product, I would buy again
    Reviewed in the United States on August 7, 2024
    Verified Purchase
    I had a set of the gen2 and liked them so when I needed a new pair decided to get the new gen3. I like them, they seem to have the same quality as the gen2 but with some new features. The rear sight windage adjustment is slightly changed with a bigger dial making it easier to use, especially while wearing gloves. The old front sight needed a tool to change the elevation, with the new one you dont need a tool, you lift the turning knob and turn it to the adjustment you want then let it go and clicks into place locking in your adjustment. This is by far my favorite change as I was always misplacing the tool the gen2 needed, it's nice to be able to make changes without the tool. The last difference is the location of the buttons to make the sight pop up, the Gen2 had them on the sides the Gen3 have it in the middle on top. They work fine but I found the location a little more awkward to press then the older ones, you have to reach up more taking your hands out of position. In summary I like them and would recommend.

    Very Tight & snug fit on a picatinny rail. Well made quality product. So tight, you may think of doesnt fit, but just had to lightly pound them on. They will only slide on from the ends. Adjustments are easy horizontal, but up/down adjustments didn't work?!? Rear sight hole is pretty small to see through.
