FMA AB163 Folding Vertical Grip — Sand

The AB163 is a folding vertical foregrip by FMA for 20 mm Picatinny rails, designed for shooters who want to keep a front grip without the bulk when the weapon is secured or stored. The folding mechanism lets you collapse the grip flush against the guard in a single motion, reducing the overall profile of the weapon.

The body is made from nylon: a material that keeps weight down and absorbs impacts without requiring maintenance, unlike aluminium which can mark the rail in the event of a lateral impact. The trade-off to consider is stiffness: nylon flexes slightly under high transverse loads, something an aluminium grip would not do. For normal operational use this is an acceptable compromise in exchange for reduced weight and noise.

The folding mechanism adds a variable to manage: the grip must be checked and confirmed locked in position before use. Anyone who never intends to fold it may prefer a fixed grip — simpler, with no moving parts to verify. Those who regularly store the weapon in cases or vehicles where space is limited will find the folding design a practical advantage.

Key points

• Folds flat against the guard to reduce bulk during transport or storage.
• Compatible with any 20 mm Picatinny rail, no adapters required.
• Nylon body keeps weight low and will not scratch the rail on lateral contact.
• A vertical foregrip improves control during rapid fire and reduces upper-limb fatigue in extended sessions.
