Full product description

Need a little extra height for your sight, red dot or micro-optic? The Nuprol RIS Rail Riser Extender (1″ 4-Slot) gives you a clean, secure and repeatable way to raise accessories off your top rail for better co-witness, iron sight clearance or to fit thicker magnifiers and mounts.

Made from machined aluminium with a matte black anodised finish, this riser is built to be lightweight but robust — perfect for airsoft AEGs, GBB platforms, and training rifles. The four Picatinny slots give you flexibility to mount a small red dot and a backup optic, offset light or a micro magnifier with consistent alignment.

Why choose this riser

• Adds 1 inch (≈25.4 mm) of height to your existing RIS/Picatinny rail for improved sight alignment.

• Four full Picatinny slots give practical mounting options without excessive bulk.

• Machined aluminium construction keeps weight down while remaining durable.

• Matte black anodised finish reduces glare and matches common rail systems.
