Double Bell JW4 Dracarys Keymod HPA Rifle Wolverine Gen 2
This is the Keymod version of Double Bell’s JW4 Dracarys HPA rifle, a film-inspired replica fitted with a Wolverine Gen 2 HPA engine. It is a showpiece rifle that still performs on the field, thanks to the consistency that HPA brings.
Double Bell’s Dracarys has become a popular choice for players who like to stand out at the safe zone, and this ready-built HPA version brings a crisp trigger and consistent shooting to the design. We also stock an M-LOK handguard version.
The JW4 Dracarys styling
The Dracarys look is inspired by the TTI JW4 Dracarys Gen-12 shotgun made famous on screen in John Wick: Chapter 4. Rather than copying the shotgun mechanism, Double Bell builds its Dracarys replicas on the M4 platform, so you get the striking styling with the straightforward handling of an AR-pattern rifle.
Our listing for Double Bell’s electric JW4 Dracarys (040) describes a metal and polymer build around a metal frame. Please check the product images for the finish and furniture of this HPA version.
The Wolverine Gen 2 HPA engine
The listing names a Wolverine Gen 2 HPA engine. Wolverine Airsoft is one of the best-known makers of HPA engines, and its current Gen 2 engine for AEG-based rifles is the INFERNO Gen 2, a solenoid-driven design that Wolverine describes as combining the easy tuning and air efficiency of open-bolt engines with easier hop-up tuning. Please contact us if you would like us to confirm the exact Wolverine engine and electronics fitted to this rifle before ordering.
Wolverine engines are tuned through adjustable electronics rather than by changing springs, and they need a small battery to power the trigger electronics as well as an air supply.
How HPA works
An HPA (high pressure air) rifle runs on compressed air from a tank, fed through a regulator and an air line to the engine in the rifle. Instead of a motor turning gears to compress a spring, a solenoid-controlled valve releases a measured puff of air for each shot. With far fewer moving parts than an AEG gearbox there is less to wear, and the trigger response is crisp and immediate.
Because the air is regulated, shot-to-shot consistency is excellent and performance does not drop away in cold weather the way gas replicas can. Power is set at the regulator, so the rifle can be tuned to suit the limits at your site without opening it up.
Handguard and handling
The Keymod handguard lets you add rail sections, a light or a grip exactly where you want them, keeping the front end slim. Make sure any accessories you buy are Keymod compatible, or use Keymod rail sections to mount standard Picatinny accessories.
The M4 controls are exactly where AR users expect them, so the rifle is quick to learn and easy to run under pressure, leaving you free to enjoy the look.

Compatibility
To run the rifle you will need an HPA air supply: a tank, a regulator and an air line. The listing does not state that any of these are included, so please check with us before ordering if you need a complete setup.
As an M4-based HPA build on the AEG platform, it is designed around M4-type AEG magazines; most standard M4 AEG magazines should fit, but fit varies between brands, so test any new magazine before relying on it in a game. Set the regulator pressure so the rifle stays within your site’s power limits, and have it chronographed before play. Start with the hop-up off, then add hop a little at a time until the BBs fly flat, and note the regulator and hop settings that suit your favourite BB weight.
Care and maintenance
Keep the HPA system clean and dry. Check air line fittings and O-rings for leaks before each game, fill your tank only with clean, dry compressed air, and have the tank tested and serviced as its manufacturer requires.
Clean the inner barrel regularly, use good quality seamless BBs, and remove the electronics battery when the rifle is stored. Follow Wolverine’s manual for engine maintenance, and use only silicone-based lubricants on seals and O-rings.
Who is it for?
This rifle is for players who want a head-turning, film-inspired replica with the consistency of HPA, and for collectors of distinctive builds who also want to use them in games.
Please note: An HPA tank, regulator and air line are needed to use the rifle and are not stated as included, and the box contents are not listed, so please ask us if you need to know before ordering. Always wear suitable eye protection when using any airsoft replica, and have it chronographed at your site before play.
