Red dot adapters for Arsenal Firearms models

This collection brings together every red dot adapter we have for Arsenal Firearms models: optics ready plates for Arsenal Firearms models with a factory optic cut, and red dot mounts for Arsenal Firearms models without one. Pick your model above and you see only the plates or mounts that fit it.

Plate or mount: which one does your Arsenal Firearms model take

• Optics Ready Arsenal Firearms models have a factory optic cut in the slide, closed with a cover plate. They take an optics ready plate. The plate goes into the cut and connects it to the footprint of your red dot.
• Arsenal Firearms models without an optic cut take a red dot mount. The mount replaces the rear sight in its dovetail. You need no slide milling and no permanent modifications.

A mount does not fit an Optics Ready model, and a plate does not fit a model without the cut. Choose your exact model, including the Optics Ready (OR) or MOS part of its name.

Optics Ready Arsenal Firearms models

We have optic plates for Arsenal Firearms (AF) Strike One pistols with a factory optic cut. They fit the Ergal and Ergal Pro Optics Ready models. American Precision Firearms (APF) versions of these pistols take the same plates. A plate connects the optic cut of the slide to the footprint of your red dot.

Two plates for different footprints

Toni System in Italy machines both plates from aluminium. The type letter in the title tells you which footprints fit:

• Type A: Shield RMSc, Leupold DPP and Docter.
• Type B: Trijicon RMR and C-More RTS.

If your red dot uses another footprint, a footprint adapter may help. See Footprint adapters.

Installation

Remove the factory cover plate from the optic cut. Screw the optic plate into its place, then screw the red dot onto the plate. No milling is needed and you can do it yourself. Threadlocker on the screws is recommended.

Arsenal Firearms models without an optic cut

We have red dot mounts for Arsenal Firearms (AF) pistols without an optic cut: the Strike One and the Mark II. The same mounts fit the American Precision Firearms versions. The mount takes the place of the rear sight, so no milling is needed.

Three dovetail widths

The Strike One and Mark II exist with different rear sight dovetails. The mount must match the width of your dovetail:

• 6.72 mm: fits the Mark II and Strike One with this dovetail.
• 11.7 mm: fits the Strike One with this dovetail.
• 11.85 mm: fits the Strike One with this dovetail.

The width is shown in brackets in each title. Measure your dovetail or check your pistol documentation before you order.

Footprints

Each width comes in two versions. Toni System type A fits Shield RMSc, Leupold DPP and Docter. Type B fits Trijicon RMR and C-More RTS. Toni System machines the mounts from aluminium in Italy.

Installation

Drift the rear sight out of the dovetail with a sight pusher or a punch. Push the mount into the same dovetail and fix it. Then screw the red dot onto the mount. No slide milling or permanent modifications are needed. See Installation tools.
