Levien Generation II MB-US Front and Rear Flip Up Sight can Mount on Any Picatinny or Weaver Rail

I have three sets of the name brand, and bought these for an extreme budget build for a friend.The quality and fidelity of the copy is frankly surprisingly good. I've seen other reviewers remark how what came in their packages was incorrect; mine came with a front sight, a rear sight, and *two* front sight adjuster tools.Comparing them side-by side with the originals, this is what I found:* The plastic is a little more matte black than the originals; not a lot, but you can tell if you hold them side by side.* The mounting screws don't come with the drop of threadlocker already on them.* The mounting screw head has sharper edges, where the original has radiused edges.* The mounting screw is labeled "<manufacturer name> USA" like the originals, but it looks engraved rather than stamped.* The mounting screw is metric instead of SAE.* The mold lines and flashing actually look *better* on the copies* The copies operate more smoothly and quietly than the originals when deploying and locking back down.* The spring tension is about the same.* The adjustments on my example work fine, and the front sight tool fits my original sights.* I had to clean a little flashing out of the small aperture with a diamond needle file, but I'm really detail-oriented on stuff like that.I don't have a doubt they'll work fine as *backup* sights. Great as a backup if you're running a red dot or magnified optic and you need something to use if you break your main sighting system. Don't think I'd take them as my first choice if I were going to war, but what do you expect for the price?4 stars only because they use the name brand trademarks. If they'd just take off the brand name and change a couple of small items to avoid the obvious patent issue, they'd have a great set of budget sights by their own right.

These are the same as my Magpul Mbus. I’ve compared them side by side and I can’t see a difference. They hold zero like a champ and are easy to operate. HIGHLY RECOMMEND

Good deal for the price work as expected seam almost as nice as magpu* only issue is the front sight detent is a bit sticky after adjusting make sure it locks in not a big thing once it’s set it seldom needs adjusting and keep in mind that that are back up sights and for that they are great 👍

These are awesome. I run mbus sights on all my weapons and figured I would take a chance on these due to the price. I couldn't tell the difference between the real magpul mbus and these besides the fastener head bolt and maybe the tension on the spring in the up position. The magpul ones have a bit more tension but not that much. I recommended these to a few buddies and they were impressed and purchased some. Would recommend. Will be getting another set. Can't beat the price for a good pair of back up sights

These are injection molded abs plastic sights with metal apertures. Says “MBUS” on elevation tool as well as on side of sights themselves but are most definitely not MAGPUL nor are they metal back up sights. Should say “PBUS” the “MBUS” inscription is off center as well which diminishes the appearance. Most importantly, THE PROVIDED ELEVATION ADJUSTMENT TOOLS (BOTH OF THEM) BROKE. The adjustment tools are also molded plastic and uses 4 studs made of plastic that interlock onto the elevation aperture to enable you to turn it either way to raise or lower the aperture. However, the 4 studs are so flimsy they rip right off in use. They provide two tools, presumably because they expect one to break, but they both broke. Luckily one of the tools only broke one stud, leaving the other three. This is sufficient to fulfill its purpose, but if you break any more than 1 stud, the tool will not properly grip the aperture and simply spin around.Overall, this is a cheap viable alternative to other options. Just be careful with the tool when making elevation adjustments.

Only had a small hole I needed to finish drilling out a little on the sight but otherwise perfect

They do fit kinda snug but work vary well i got front and rear and i got 2 tools for the front sight.

Typical sights for AR-15 fully adjustable front adjustable up & down rear 100-300 windage adjustable
