Red dot adapters for American Precision Firearms models

This collection brings together every red dot adapter we have for American Precision Firearms models: optics ready plates for American Precision Firearms models with a factory optic cut, and red dot mounts for American Precision 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 American Precision Firearms model take

• Optics Ready American Precision 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.
• American Precision 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 American Precision Firearms models

We have optic plates for American Precision Firearms (APF) pistols with a factory optic cut. They are also called optics ready plates. The plates fit the Strike One Ergal and Ergal Pro Optics Ready models. The same plates also fit the Arsenal Firearms Ergal and Ergal Pro. The plate goes into the optic cut and lets you mount a red dot with a matching footprint.

Choose the plate by your red dot footprint

Both plates are made by Toni System in Italy from aluminium:

• Type A fits red dots with a Shield RMSc, Leupold DPP or Docter footprint.
• Type B fits red dots with a Trijicon RMR or C-More RTS footprint.

Check the footprint of your red dot first, then choose the type that lists it.

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.

American Precision Firearms models without an optic cut

We have red dot mounts for American Precision Firearms (APF) pistols without an optic cut. They fit the Strike One and Mark II. The same mounts fit the Arsenal Firearms versions. The mount replaces the rear sight. You need no slide milling and no permanent modifications.

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.
