Description
Ares Keymod Flip-Up Rear Sight (Black – AS-R-021)
This is an Ares flip-up rear sight in black, listed for KeyMod rail systems and coded AS-R-021. A flip-up rear sight folds flat out of the way when you are using an optic, and flips up to give you a usable iron sight in moments.
Ares is a well-known Hong Kong manufacturer of airsoft rifles and accessories. Back-up iron sights are a sensible addition to any optic-equipped rifle, because a red dot can run out of battery, steam up or take a knock, and it is good to have a fallback. Many players also prefer to run iron sights all the time for a light, simple setup.
How flip-up sights work
When folded, the sight lies low and does not get in the way of an optic. Flipping it up stands the aperture in your line of sight, ready to line up with a front sight. Rear sights are normally mounted at the back of the upper receiver rail, closest to your eye, and paired with a matching front sight further forward.
Our listing does not give the material, the aperture type or the adjustment features, so please check the product images for these details.
Mounting
The listing names this as a KeyMod sight, so check how it attaches to your rail in the product images before ordering. Rear sights are usually fitted on the flat top rail of the upper receiver, so confirm where you plan to mount it and that the interface matches.

Compatibility
Listed for KeyMod. Check your rail and the mounting method in the images before ordering, and pair it with a front sight of a matching height so the two line up. If you also run an optic, check that the flip-up sight sits low enough to fold away beneath it.
Care and maintenance
Check that the mount is tight before each game and that the sight locks firmly in both the folded and raised positions. Wipe off mud and grit, especially from the hinge, and let it dry if it gets wet.
A tiny drop of light oil on the hinge now and then keeps it moving smoothly. Store the rifle with the sight folded to protect it from knocks.
Who is it for?
This sight suits players who want a fold-away back-up iron sight for a rifle, or a simple, light sighting system.
Please note: The front sight and rifle are not included.
