Description
The Recover Tactical S-PRO Upper Rail is a dedicated mounting section built for the S-PRO pistol conversion kit. It gives you a proper 5-slot Picatinny surface up top, which opens the door to running an optic or other gear that needs a stable, repeatable mounting point. If you've been running your S-PRO without a good way to add glass, this is the piece that fills that gap.
How the S-PRO Upper Rail Attaches
The rail is designed to bolt onto the M-LOK slots found on the S-PRO frame. That keeps things modular, so you can position it where it makes sense for your setup and your eye relief. The S-PRO uses M-LOK slots on either side and up top for exactly this kind of expansion, and this upper rail is the clean, purpose-built answer for adding a Picatinny section rather than piecing something together.
Running Optics on the S-PRO Rail
This uses a standard 1913 Picatinny spec, so as long as your optic mount is Picatinny compatible, it should drop right on without drama. Red dots are the natural pairing here since a slide-mounted optic can be tricky to run on a conversion kit, and having a dedicated upper rail lets you mount a dot at a height that works for you. Worth noting: this is the S-PRO upper rail specifically, not a universal M-LOK-to-Picatinny adapter and not compatible with the older 20/20N polymer setup.
What to Expect from This Upper Rail
Recover Tactical built its name on lightweight, refined conversion kits that lean into the compact PDW idea, and this rail fits right into that philosophy. It's a small part that makes a real difference in how you can build out your S-PRO, whether you're setting it up for the range or just want a cleaner, more capable platform. Installation is straightforward with basic tools, and once it's on, you've got a durable base for whatever you want to mount.

Frequently Asked Questions
What does the S-PRO Upper Rail mount to?
It's designed to attach to the M-LOK slots on the Recover Tactical S-PRO conversion kit. That gives you a solid, purpose-built Picatinny surface for adding an optic or other gear. It is not a universal M-LOK-to-Picatinny adapter for other platforms.
Will my optic mount fit this rail?
The S-PRO Upper Rail uses a standard 1913 Picatinny spec, so any Picatinny-compatible optic mount should fit without issues. Red dots are a popular pairing since they're easy to run at a comfortable height on a conversion kit. If your mount clamps to standard Picatinny rails, you're good to go.
Is this compatible with the 20/20N kit?
No, this upper rail is built for the S-PRO platform and is not compatible with the older 20/20N polymer setup. If you're running an S-PRO, this is the right piece. For other Recover kits, look at their model-specific upper rails instead.
How hard is it to install?
Installation is straightforward and uses basic tools with the supplied hardware. Because it mounts to M-LOK slots, you can position it to suit your eye relief and setup. Once it's tightened down, it gives you a stable, repeatable base for your optic.
