Compatibility & Fitment
Fits: Mossberg 500 / 590 / Maverick 88 12-gauge receivers.
Notes: Side plates, heat shields, oversized safeties, or aftermarket accessories may affect clearance. Confirm your receiver configuration before installation.
Installation Notes
Mounts directly to the receiver using the included, model-specific hardware (follow the manufacturer instructions).
Tighten to recommended torque; use thread treatment if specified.
With the firearm unloaded, perform a function check to ensure smooth action cycling, proper ejection, and that staged shells do not obstruct the ejection port.
Carry & Staging Tips
Brass down = speed: Ideal for emergency port loads or rapid tube feeds.
Brass up = retention: Better for extended movement or rough terrain.
Color code & sort: Use hull colors (or position) to differentiate buckshot vs. slugs at a glance.
Rotate shells: Periodically swap rounds to maintain consistent retention and inspect hull condition.
Care & Maintenance
Wipe down with a soft cloth and mild firearm-safe cleaner; avoid heavy oils on the retention cells (can reduce grip).
Inspect mounting hardware regularly, especially after high round counts or hard use.
Keep cells free of debris to maintain smooth, predictable draws.
