DonnyFL EMPEROR +P .457/50 cal with M18x1 Endcap - Airgun Moderator

The Emperor v3 +P is built for shooters running the newest generation of high-pressure big-bore PCP rifles. This upgraded +P version features a strengthened internal system with an extra layer of metal mesh, secured with stainless-steel straps and additional zip-ties for superior durability and consistent performance under extreme pressures.

Already known for its impressive sound suppression, the Emperor v3 +P retains its modular design—allowing you to add an optional 6.5-inch extender for even quieter shots—and maintains the rugged feel and reliability DonnyFL is known for.

Key Features:
• +P reinforced internals with metal mesh & stainless-steel strapping
• Built for .457 to .50 caliber high-power airguns
• Mono-core design for strength, accuracy, and minimal clipping
• Optional 6.5-inch extender for maximum suppression
• Precision CNC machined 6061 aluminum body
• Pre-wrapped in felt and mesh for noise reduction
• Easy-grip machined grooves for handling
• Lightweight (approx. 16 oz) and includes protective storage tube

Stronger, quieter, and engineered for high-pressure and short-barreled big-bore airguns—the Emperor v3 +P is the ultimate moderator for serious high-energy airgun setups.

Important Information:

• Adapter May Be Required: The Moderator does not come with an adapter. Best results will come with a threaded barrel. Please check our adapter section for the specific adapter associated with your air rifle. If you are using a slide-on adapter, we recommend drilling a divot into your barrel to match each of the set-screws for a more secure installation.
• Regular Inspection: Regular removal of the monocore from the shell to inspect the strapping, mesh and felt is necessary for safety, effectiveness and long life of this moderator. Watch for breakage of the plastic zip ties and bunching of the felt, and smooth and replace as needed.  These internal components are consumable, and refreshing/rebuilding services are available.
• Intended Use: Made for airguns only. Will not work for firearms. Please read the disclaimer.
• Tex-Rex Carbine: We have successfully tested the Emperor +P with the full-length AirForce Tex-Rex, but have had limited opportunities to test it with the Carbine version of the Tex-Rex. Based on customer feedback, we do not recommend this moderator for the Tex Rex Carbine at this time.
• International Customers: If you add this item to your cart, shipping options will not be available for restricted items. Non-restricted items will also not show up until the restricted item is removed.
• Return Policy: Please review our return policy for more details.
