Benjamin Bulldog .357 Cal Moderator Adapter w/ thread protector #A41
$44.99
Adapters are threaded for attaching a moderator
Thread: M18 x 1
The new adapter have finally arrived. This new design goes back to the barrel and slides over the barrel bushing. This will keep the barrel aligned with the adapter's exit hole. Please note that the barrel bushing is not included.
The .357 Benjamin Bulldog is becoming popular for big game hunting. Add this adapter and pair it up with a .357 Ronin or .357 Emperor to make it the ultimate hunting airgun.
The factory gun already has the barrel bushing. I took mime off to show how it fits into the adapter in the picture.
Made by CNC for accuracy
Very easy to install. Remove the top and bottom screw securing the front cap and swap it out for this adapter. Screw the two screws back in and you're done. No need to remove the shroud.
Matte Black anodize
Knurled thread protector
When putting this on, press the adapter into the shroud as you tighten the two screws. This will ensure the adapter is flush with the shroud.

Benjamin Marauder Pistol (Prod) & Daystate Huntsman Regal Moderator Adapter #A17
$39.99
Adapters are threaded for attaching a moderator
Thread: 1/2 x 20 UNF
Want to make your Prod quieter? You'll need this 1/2 x 20 adapter that will screw into the OEM shroud. The threads that screws into the shroud is 11/16 - 24.
The .25 Sumo 1/2 x 20 is my favorite suppressor for this gun. The .25 works great with the .22 and reduces the chance of pellet clipping. However, in order to fill this gun with the Sumo, you'll have to remove the suppressor. An alternative is to go with either the Tanto or KOI with cone rear cap.
*Highly recommend going with a caliber one size up to reduce the chance of pellet clipping.

DonnyFL | Air Venturi Alpha Adapter
from $40.00
Make your Air Venturi Alpha compatible with DonnyFL Moderators with the DonnyFL Alpha Adapter. Designed specifically for the Alpha platform, this adapter provides a 1/2 x 20 UNF male thread for mounting compatible DonnyFL airgun moderators.
The Alpha is available with both traditional air tubes and larger bottle configurations, so we developed two adapter lengths to provide the proper fit for either setup.
Short Version: Designed for Alpha tube configurations where minimal additional clearance is required. This adapter creates just enough clearance so that you can add a moderator of any size and access the fill probe hole without removing the moderator.
Long Version: Designed for bottle-equipped, Compact Alpha models. The extended body moves the moderator mounting point forward, providing the additional clearance needed for the moderator body to clear the larger air bottle.
The adapter features a knurled exterior for an easy grip during installation and removal and includes a matching knurled thread protector to protect the exposed threads when a moderator is not installed.
Features:
Designed specifically for the Air Venturi Alpha .22 PCP
1/2 x 20 UNF male moderator threads
Available in Short and Long configurations
Short version designed for tube-equipped Alpha models
Long version provides additional clearance for bottle-equipped, Compact Alpha models
Knurled exterior for improved grip
Includes knurled thread protector
Black anodized finish
Designed for airgun use only
Pro-Pairing:
Our team likes the .22/25 cal Sumo with 1/2x20 threads on the Standard or the .22/25 cal Shogun with 1/2x20 threads on the Compact versions of the Alpha.

DonnyFL | EMPEROR +P .457/50 cal with M18x1 Endcap - Airgun Moderator
$249.00
Product description
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.
