Avengers M4 M16 300 & 600M Style Flip-up Rear Sight for Airsoft Rifles - Black

"It's a good sight for the price!

Pros:
Small low profile
Durable
Adjustable (only left and right)
Flip up action sweetness!
Two sight modes
Nice little baggy it comes with (listed as golden eagle, not d boys version)

Cons:
Paint scratches lightly after use
Manually have to lift up latch to secure down sight
Weak nut
Peep sight is deformed to the left (only a defect on mine)
Actuall sight rattles a bit but can easily be fixed
No trades like real

Over all, for the money and quality I give it a five stars. It's real nice to have reliable back up sight in case all electronic sights shut of (reference).

"This sight is great. I have it on my KWA KM4A1 without any other optics. I t is durable and spring is strong. The only complaint i would have at all is the bad paint. The paint chips easy but Its really not all that bad. I think the worn look looks good on my gun.

"looks great on the ics m4. it should be used with front sights by the same manufacturer

"does anyone know whether this will work for any gun?

"For those looking into a rear BUIS, I highly recommend this one over all others. When collapsed, it's got a low profile and is easily compatible with most scopes and red dots. When in use, one can switch between night and standard AR sights. A beautiful accessory for those who use their rifles for a multitude of scenarios.

"The Avengers Flip-up sight has a cheap feel & look. Does the job, but only just. Small aiming aperture snapped right off after first attempted use. Large aperture still intact, for now. I would not recommend or buy again.

"Okay sight for the money. Wobbles a little on my G&P M4 rail, and after just a few times of taking it on/off, the screw literally broke. The piece that fits in the rail slot snapped. Could not glue it back together either. Would not buy again, but if you just need a cheap sight, go for it. I could have just been unlucky
