Introducing the EPIC ONE – the new icon from the world‑renowned company EPIC AIRGUNS based in the Czech Republic. The EPIC team has drawn on all the experience gained from producing the successful TWO model and transformed it into its compact bullpup successor. The high manufacturing quality is evident from every angle – for example, the main monoblock of the air rifle is machined from a single piece of metal on a 5‑axis CNC machine.

PCP SYSTEM
This bullpup boasts a new adjustable HIGH-POWER balanced valve which ensures maximum performance with minimal hammer spring preload, making it easier to cock the side lever. At the same time, it reduces air waste and thus increases the shot count per fill. Hammer preload can be adjusted externally via a screw located above the buttpad.
The air cylinder with a maximum working pressure of up to 300 bar (4350 PSI) can be filled using the supplied fill probe with a standard 1/8" diameter compatible with a standard quick‑coupler. The air rifle is equipped with 2 manometers – one indicates the current pressure in the cylinder, the other the pressure in the externally adjustable regulator, which can be set with the included tool in the range from 50 to 190 bar (always follow the instructions in the manual).
To achieve even more consistent muzzle velocity, the regulator is complemented by a large power plenum (63cc for the version with 420mm barrel and 95cc for 550mm and 700mm barrels).
BARREL
EPIC ONE air rifles are fitted with an unchoked CZUB barrel (Česká zbrojovka Uherský Brod) with 12 grooves and a 17.7” twist rate. The muzzle end is equipped with a 1/2UNF thread for mounting a sound moderator. The carbon shroud serves to stiffen the barrel and also allows barrel preload (harmonic tuning).
Air rifles with 420mm and 550mm barrels are additionally equipped with an integrated K‑Baffle type sound moderator, also ending with a 1/2UNF thread.
On the version with a 700mm barrel, after unscrewing the segment with the 1/2UNF thread and exposing the M27x1 thread, it is compatible with the EPIC AIRGUNS sound moderator or with a muzzle brake.

Barrel kit
Thanks to the barrel kit, you can freely change the barrel length and overall calibre of the air rifle. The set includes everything needed (barrel, carbon shroud with M27x1 thread, 1/2UNF moderator adapter, 1/2UNF thread protector, transfer port and loading probe).
For the very best results with heavy pellets and slugs, there is also a barrel kit available with an unchoked polygonal Lothar Walther barrel (6 grooves with a 17.7” twist rate).
MAGNETIC MAGAZINE
The ONE series is equipped with a new pre‑tensioned magazine with magnetically closed cover. To fill it, simply rotate the inner section and insert the first round, which locks the rotary mechanism. Thanks to its compact dimensions, the magazine does not disturb the overall look of the air rifle and does not get in the way when handling it. In addition, it accommodates projectiles up to 14mm in length.
BULLPUP CONSTRUCTION
Thanks to the smart bullpup design, the ONE model achieves exceptionally compact dimensions while the air rifle is perfectly balanced. For maximum shooting comfort, the stock is fitted with a length‑adjustable buttpad with a textured contact surface and a QD mount for a sling. The Bag Rider visible in the photos is not included.
Proper cheek weld is ensured by a rubberised cheekpiece that can be freely moved along the 11mm dovetail rail running along the entire main block of the air rifle. The raised Picatinny rail with up to 30 MOA incline is also adjustable and makes it easier to zero your scope for shooting at extreme distances.
You can also purchase the Top Rail EPIC ONE – a tuning Picatinny rail with a series of M‑LOK slots on the sides – or an Arca‑Swiss mounting platform for versions with a 580cc and 300cc carbon bottle.

To attach additional accessories, you can use two short Anschütz UIT rails on the sides of the barrel or the series of M‑LOK slots located between the buttpad and the standard AR‑15 type grip.
The trigger mechanism has been fine‑tuned to the smallest detail. Using several screws, you can adjust the trigger pull weight, first and second stage travel, as well as the height and rotation of the trigger blade. The reliable lever safety is located directly in front of the trigger, so you do not need to take your eyes off the target when disengaging it. The easily reversible side lever with an extremely smooth action is already a given on EPIC air rifles.
VARIANTS / CONFIGURATIONS
EPIC ONE is available in three design variants:
- Classic – standard aluminium air cylinder and short bottom Picatinny rail
- CFB (Carbon Fiber Bottle) – carbon bottle and short bottom Picatinny rail
- CFB Arca-Swiss – version with carbon bottle complemented by an Arca‑Swiss mounting platform with a series of M‑LOK slots on the sides and a bottom Anschütz UIT rail

NOTE – The EPIC ONE air rifle offers numerous options for adjusting internal and external components, and some modifications require extensive knowledge of PCP air rifles. Always follow the user manual – incorrect procedures may result in irreversible damage to the air rifle and loss of warranty.
