Product Information:
I put this site on my M4 to replace my carry handle and it added the extra look that most of us are looking for. I got exactly what I paid for and let’s be honest the site is for an airsoft gun it is not really for aiming. Although I did look through the sites and they lined up perfectly with a little adjustment of course.

1) Looks great on my M4.
2) Fits securely on the upper rail and was simple to put on.
3) Folds down easily and flips up just as easy.

1) There are no cons because like I said before we buy these sites for looks and in terms of looks this thing rocks. If you really need a site to hit a target less than 200 feet away this thing will still do the trick.

Product Information:
I bought this sight a few months ago, and unfortunately it was shipped to me without a means to mount it. The clamp that you see on the left side was MIA, as was the screw. I contacted ASGI's customer service, explained the problem, and unfortunately got nothing. I decided to simply let it go and made my own mount and screw.

Once that was done, the sight functioned great. Assuming that you would receive this item with all of the intended parts, its great and I would recommend it. It looks good folded down when using a red dot, and it also looks great as a substitute for the carry handle sight on an M4.

Looks great

Mine didn't come with a mount, but that's a fluke
A little pricey, but what're ya gonna do?

Product Information:
When I ordered the sight I expected it to be ready to fit on my M16 right out of the box but it required needle nose pliers in order to have it tight enough so it didn't wiggle around. The finish is overall very nice, the needle nose pliers didn't do any damage to the finish or the tightening mechanism itself. The only qualm I have about the finish is that it is a bit too dark, more like a black than a matte black or gun metal grey color. The sight itself takes a little breaking in before it works properly, sadly you cannot close it with the peep down but that's a fact of the real one also. The spring shows signs of wear but it's nothing to serious. To flip the sight down you need to pull the latch back so you need both hands and that can be a bit cumbersome especially when you're in a fire fight. It adjustable for windage (left to right) but you need to have the peep up to do that but once you have adjusted you can flip the peep down. There are some molding marks but nothing too serious.

Overall it's a great sight and it gets the job done, realistic markings and a few minor adjustments would be a definite plus but it's from a Chinese company so what can you expect. Not really worth $25 more like $20 but it's still much less than a $70 Guarder sight and if you have a red dot sight this is just a back up. I give it 4 stars, there are minor improvements that could be made but it's good for the price.

-Gets the job done
-Small and large peep
-Adjustable for windage (left to right)
-Tough finish
-Fits all rails
-Low profile

-Loose at first
-A bit too pricey
-No marking
-A few mold lines

Several points to touch on.

First, this isn't "B-2" brand. It's DBoys, their copy of the ARMS #40 rear sight. That said, it's a decent cheap flip-up BUIS.

Second, the QC is a little off. My rear aperture was crooked because DBoys couldn't drill a straight hole perpindicular to the side of the unit, and as a result the angle of the screw which allows side to side adjustment was a bit off.

Third, the paint is incredibly low quality and will wear off rather shortly.

For the price, I highly recommend the Samurai or Action flip up rear sight, which are also copies of the ARMS #40 and is available from most Hong-Kong based shops with airmail shipping being roughly the same. Both offerings are also much higher quality.

Finally, the spring which held the retainer lever in place on mine was incredibly low quality and no longer functions quite as it should - the rear sight is held down when folded compactly, but I'm not impressed with the overall quality.

I hope this helps you to make your decision about buying - it's not a bad sight, but for the price point it's also not that great.

I never had a problem with mine; mounting it on the rail took a little patience but no sanding or modification. I did try to mount it on a DPMS Panther M4 clone and found it wouldn't fit because the rail was just a tad wider than 20mm- maybe the same is true for other models from different companies- I will admit the fit is VERY tight on this piece, but that results in an extremely solid mount. I had no problems with the aperture sight being loose either. I can only speculate that the other reviewers were unlucky and got sights from a different production run than mine. I give five stars, there's not a thing wrong with this sight.

If you read the other guys review you prob wouldnt want to buy this sight, but i said what the heck i'll give it a shot. When i got it in i will say it was hard to get onto the top of my m4, but with alittle sanding it went on fine and didnt take any paint off of the gun. The only bad thing i do have to say about this sight is that peep part is way to lose, but is an easy fix if your a handman. So overall i'll give it a 4 out of 5, beacuse its worth the $25. Thanx airsoft GI

This design looks good, but there are a few major flaws. The first is that only a portion of the claw moves, meaning you have to slide it over the rail to get to proper location, then screw it tight. This normally wouldnt be much of a problem, but the one that I got was a terrible fit on my ICS m4 rail. It actually stripped the finish on the edge of the rail when it was being put on.

It did eventually get in place, but the rod that goes through the gaps to tighten the claw in the rail isn't a traditional circle/curved shape. Its a square, and mine wouldn't fit because one of the corners was mis-shaped. A bit of sanding might help, but it should have been functional out of the box.

Having said that, you can only close it with the close range right up, it wont close if you have the smaller peep hole up. The peep sight itself is extremely loose.

This is my first experience with a B-2 product, and IMO there is no way this should have gotten past QC, so this will also be my last.
