Outerimpact Modular Red Dot Adapter for SIG P320-X5

• Modular optic compatibility: This adapter accepts multiple mounting standards, making it easier to fit different pistol red dots on a SIG P320-X5 without committing to a permanent slide modification.
• 7075-T6 aluminum construction: The plate is machined from high-strength aluminum, giving the mount the rigidity needed to handle slide movement while keeping added weight low.
• Steel alignment pins and Weaver-style screws: These parts help keep the optic properly indexed under recoil, which supports repeatable alignment and reduces the chance of the sight shifting in use.
• Low-profile 0 MOA design: The flat mounting geometry keeps the optic close to the slide, preserving a clean pistol setup and a natural presentation for fast sight acquisition.
• Made in the USA: Domestic manufacturing and model-specific fitment give this red dot adapter a more purpose-built feel for shooters setting up a competition or range pistol.

About the - Series

Leupold’s Quick Release (QR) system was developed around a lever-operated locking mechanism that secures QR rings into steel bases while allowing the optic to be removed and reattached with minimal shift in zero. In Leupold’s lineup, the QR family has long been associated with practical field use, especially on muzzleloaders and large-caliber rifles where shooters may want to swap optics or remove a scope for transport and maintenance.

The system was offered in one-piece and two-piece base configurations and was built to work specifically with Leupold QR rings. A key idea behind the design was flexibility: one rifle could be set up for different tasks by changing optics while still maintaining useful return-to-zero performance. Leupold described the system as capable of returning within 1/4 MOA when removed and reinstalled correctly. Some variants, such as the QR Gunmakers two-piece base, were later discontinued, but the QR concept remains a recognizable part of Leupold’s traditional mounting solutions.

About the Outerimpact Modular Red Dot Adapter for SIG P320-X5

The Outerimpact Modular Red Dot Adapter for SIG P320-X5 is built for shooters who want to add a pistol red dot without machining the slide for a single footprint. Its main advantage is flexibility: one adapter supports several common mounting standards, including Docter, Trijicon RMR, Shield RMS, Leupold DeltaPoint Pro, C-More RTS and Holosun 407K/507K patterns. That makes it useful for testing different optics, replacing a sight later, or standardizing one pistol around whichever red dot best suits competition, range, or general handgun use.

The mount uses a 0 MOA layout and a compact profile, so the optic sits in a straightforward, slide-mounted position without adding unnecessary bulk. Outer Impact machines the plate from 7075-T6 aluminum, a material chosen for its combination of strength and low weight, which matters on a reciprocating pistol slide where every added ounce affects handling. The use of steel alignment pins and Weaver-style T-10 Torx screws is equally practical: these components help the optic stay properly located under recoil and support a more secure installation than a simple screw-only interface.

For the SIG P320-X5, this adapter is a practical way to move into slide-mounted pistol optics while keeping the setup reversible. It suits shooters who want a cleaner route than custom machining and who value the ability to change sight patterns as their preferences evolve.

About Outer Impact

OuterImpact is a firearm-accessory brand operated by Outlander LLC. Its catalog focuses on practical mounting solutions, including modular red-dot adapter mounts, micro adapters, and Picatinny-based platforms for handgun and rifle applications. Within this category, the brand is known for building around broad optic compatibility rather than limiting the user to one footprint.

OuterImpact describes its red-dot adapter mounts as using steel alignment pins together with Weaver-style screws to keep the optic properly aligned under recoil. The company’s product range includes adapters for multiple firearm platforms and supports red-dot sights from several manufacturers, which reflects a design approach centered on interchangeability. In its mounting products, OuterImpact also references materials such as 7075-T6 aluminum and black anodized finishes, showing a clear emphasis on lightweight but durable construction for slide- and rail-mounted optics.
