Description
Ares Keymod Flip-Up Front Sight (Black – AS-F-021)
This is an Ares flip-up front sight in black, with the Ares code AS-F-021. Our listing names it as a Keymod flip-up front sight. A retailer listing for the same code describes it as a reinforced nylon fibre flip-up front sight for a Milspec 1913 Picatinny rail, made for the Amoeba series and other replicas, with a very light weight of about 10g.
Because these two descriptions differ on the mounting type, please check the mount in the product images against your rail before ordering. Either way, a flip-up front sight is a sensible, light backup to an optic, and folds down out of the way when you do not need it.
Why fit flip-up sights
Optics can fog, run out of battery or take a hit. A flip-up front sight, paired with a matching rear sight, gives you a simple backup that is always on the rifle. When folded, it sits low enough that it does not block the view through most red dots and holographic sights.
Flip-up sights are also popular on their own for players who like simple iron sights and want to save weight.
Fitting and using
Mount the front sight on the front of your top rail or handguard and pair it with a rear sight, so the two line up. Flip it up, check the sight picture, then adjust your hop-up and point of aim at your usual engagement distance. Fold it down when using an optic.
Key features
- Ares flip-up front sight
- Code AS-F-021
- Black finish
- Light reinforced nylon fibre build (as listed by a retailer)
- Folds down out of the way of optics

Compatibility
Our listing names this as a Keymod sight, while a retailer lists the same code for a Milspec 1913 Picatinny rail. Please compare the mount in the product images with your handguard or rail before ordering, and contact us if you are unsure. You will also need a rear sight to make a complete sight set.
Care and maintenance
Wipe the sight clean after muddy or wet games and check that it is still secure on the rail. Avoid over-tightening the mount, as nylon fibre parts can crack under too much force. Fold the sight down when transporting the rifle to protect it from knocks.
Who is it for?
For players who want a light, low-cost backup front sight for their M4 or Amoeba-style replica, or a simple iron sight set-up.
Please note: This is a front sight only; a rear sight is not listed as included. Please check the mount type in the images before ordering.
