Kross Airsoft Design MK23 Under Rail

The Tokyo Marui MK23 ships without a meaningful accessory rail — the gun was designed in an era when pistol-mounted lights and lasers weren't standard kit. KAD's MK23 Under Rail addresses that gap, fitting a full picatinny rail section beneath the barrel where you can mount any standard rail accessory.

Useful in night games (mount a torch), low-light skirmishes (a green laser for fast aiming), or stealth scenarios where you'd benefit from forward purchase for prone shooting (a small angled foregrip). Direct fit to the MK23 — no gunsmithing or permanent modification.

What to mount on it

Single CR123 weapon lights are the most common addition — a quality compact light gives you target identification at indoor or night events. Green lasers are popular for fast-shooting scenarios; they appear instantly on target without needing sight alignment. For sniper builds, a small bipod or hand stop mounted underneath can stabilise the gun for extended hides. Pick whatever your role needs — the rail handles them all.
