About This Stoeger M3000/M3500 Mount
This low-profile direct mount connects the optic to a tapped Stoeger M3000 or M3500 receiver without a separate Picatinny rail and optic mount.
Compatibility
This mount fits Stoeger M3000 and M3500 shotguns with tapped receivers.
Choose the Correct Receiver Screws
Use the shotgun's serial number to identify the receiver thread. Models before serial number 1368845 use two #6-48 x 1/8 flat-head screws. Serial number 1368845 and later use two #8-40 x 3/16 flat-head screws.
Fixed bundles include both receiver-screw sets. Use only the set that matches your receiver.
Installation Notes
Unload the firearm completely. Remove the magazine, clear the chamber, and remove any factory rail or other mount. Position the Armadyne mount on the tapped receiver and secure it with the receiver screws that match the shotgun's serial-number range.
Attach the optic to the mount and dry-fit the assembly on the receiver before final installation. Confirm that no optic screw protrudes far enough to contact or scratch the receiver.
Tighten #6-48 receiver screws to 10 in-lb when installed dry. Tighten #8-40 receiver screws to 15 in-lb when installed dry. Liquid thread locker is optional; if used, reduce torque to 7.5 in-lb for #6-48 screws or 11.25 in-lb for #8-40 screws.
Follow the installation instructions for the complete optic-screw check, torque values, and optional thread locker guidance.
