Apex Optic Mount for ACRO/MPS* - Sig P320 RX and RX Pro
*We highly recommend using the Apex Super Clamp to expand the clamping range of your MPS optic
The Apex Optic Mount is designed to securely mount the Aimpoint® ACRO Series or Steiner MPS* optics to the Sig Sauer P320 slide with the RX Classic cut or RX Pro cut. The Apex Optic Mount is machined from a billet of steel and black oxide finished. The inclusion of the Optic Sub Plate allows the Acro Locking Bar to fully engage the mount to prevent walking and damage from heavy use.
- Works with models equipped with the factory Loaded Chamber Indicator
- The Apex Optic Mount is model-specific. Please see part #112-009 if your P320 has the rev2 slide cut (will have "-R2" in the SKU).
