UX RaceGun CO2 4.5mm BB Blowback Air Pistol Set by UMAREX
The UX RaceGun is Umarex leaning fully into the “competition style” CO2 pistol idea. It’s based on IPSC-style race setups, meaning it’s built for speed, fast handling, and lots of visual “look how serious I am” energy.
It comes pre-kitted with the kind of accessories people usually end up buying later anyway, so it’s more of a ready-to-run speed platform than a standard replica pistol.
Key Features
- Full metal blowback system with fast cycling action
- Single action trigger tuned for quick response
- Compensator, jet funnel, and extended controls included
- Adjustable and exchangeable sights
- Picatinny bridge mount for optics
- Includes free GDS point sight
- 22-round magazine
- IPSC-style race pistol design
Performance / Use Case
This is built for speed shooting style use, not precision target work or realism training. Everything about it is aimed at fast target transitions, quick sight acquisition, and reduced handling time between shots.
The extended controls and jet funnel are there to make reloads and manipulation smoother, especially under timed or competitive-style shooting. The blowback action is fairly sharp, but like all CO2 race-style setups, efficiency is not the main event here.
Accuracy is fine for short range reactive targets, but if you’re expecting tight groups at distance, this is not the right personality type of pistol.
Build & Design
At just over 1kg, it has a solid, competition-style weight that helps with recoil control during rapid fire strings. The full metal construction keeps it stable, while the longer frame and attachments give it a very “ready to compete” look.
The Picatinny bridge mount is a big practical upgrade, letting you run a red dot without awkward side mounts or compromises. The included GDS sight means it’s usable out of the box without immediately needing extra purchases, which is always suspiciously helpful.
Controls are extended and exaggerated, which is exactly what you want in a speed-focused setup where fiddly is the enemy.

The Racegun is very clearly built for one thing: going fast. It’s not subtle, it’s not traditional, and it definitely isn’t pretending to be a duty pistol.
What it does offer is a ready-made speed shooting platform with most of the “upgrades” already included, which saves you the usual rabbit hole of bolt-ons and experimentation.
If you want controlled precision, look elsewhere. If you want to run stages in your head like you’re in a competition you’ve definitely not entered, this fits the brief quite well.
Important — read before purchase or storage.
All CO2 and green‑gas/propane powered guns and magazines are pressure systems and must not be stored pressurised for any length of time outside active shooting. Leaving gas installed will compress internal seals, accelerate permanent leaks, and shorten the life of your gun.
Temperature & Pressure Behaviour
CO2 and propane are temperature‑sensitive: they expand and contract with temperature changes. That expansion can force gas past worn seals or, in extreme heat, rupture seals or valves — creating dangerous failures. Keep guns and magazines out of direct sunlight and away from heat sources. Cold temperatures reduce pressure and can cause low power or feed problems, so always test a gas gun in the conditions you intend to use it.Always remove or fully vent gas after use. If you’re not shooting, remove the CO2 capsule or vent/empty magazines. Do not store with gas installed.
Lubrication Recommendations
To protect internals and seals we recommend using gas with added lubricants:-
CO2: use lubricated CO2 capsules — UMAREX branded CO2 is our recommendation.
-
Green Gas / Propane: use gas with added lubricant such as Vorsk, UltraAir, Nuprol, or Abbey (Green Gas).
Seal & Lubricant Guidance
-
Apply one drop of silicone oil (for polyurethane seals only — usually green or clear seals) to the tip of every 5 CO2 capsules or before long‑term storage to lubricate the piercing nozzle and protect seals.
-
For silicone seals (typically semi‑translucent white), only use PTFE‑based lubricants (e.g. Super Lube PTFE). Do not use silicone oil on silicone seals.
-
Never use gas cartridges showing rust or visible corrosion.
Leak Expectations & User Responsibility
All gas systems will slowly leak over time. Proper care reduces the rate of leakage but cannot prevent it entirely. Leaving cartridges installed dramatically speeds up seal wear. By using or storing gas guns you accept responsibility for regular maintenance, correct lubricant use, and safe storage.We Test Before Sale
We test every gas‑powered gun prior to dispatch or handover for major leaks and function. This may mean the gun arrives with gas installed — you may choose to use this free gas or vent the gun before storage. Testing does not guarantee seal life or prevent future leaks; seals remain consumable parts.If you’re unsure about seal types, lubricant compatibility, or safe storage, ask us before purchase — we’ll give honest guidance. Failure to follow these recommendations may void warranty or return eligibility where damage is caused by improper storage or lubrication.

Important Notice for the Purchase and Delivery of Airguns, Pressure Components of Airguns, and Moderators
Effective Compliance with the Violent Crime Reduction Act 2006 (VCRA): Sections 31 and 32
Under the provisions of Sections 31 and 32 of the Violent Crime Reduction Act 2006, which were enacted through "The Violent Crime Reduction Act 2006 (Commencement No 3) Order 2007: firearms measures," specific regulations now apply to air weapons, their Pressure-Bearing component parts, and certain accessories.
Key Points to Note:
Restricted Items:
- Airguns: All airguns are classified as restricted items.
- Pressure-Bearing Parts of Airguns: This includes barrels, cylinders, reservoirs, and pistons.
- Functional Moderators (Silencers/Suppressors): Moderators that reduce the sound of discharge are also classified as restricted items.
Definition and Registration:
- Component Parts: While the VCRA does not explicitly define "component parts," the Home Office interprets this to include pressure-bearing parts such as barrels, cylinders, reservoirs, and pistons.
- Accessories: Only moderators (silencers) require registration by dealers.
Legal Requirements for Transfer:
- In-Person Transfer: It is an offence under the VCRA to transfer these restricted items through standard postal systems or to the end customer directly without the presence of both the buyer and either the seller or a representative of the seller.
- Representatives of the Seller: This can be:
- An employee of the seller who is a registered firearms dealer (RFD).
- Another RFD authorized by the seller.
- An employee of the authorized RFD.
Collection and Delivery Options:
- Collection from Store: Customers are encouraged to collect their restricted items directly from the store where purchased.
- Transfer to Another RFD: Items can be transferred to a local RFD for collection, though the receiving RFD may charge a fee for this service.
- Home Delivery: We offer home delivery through our in-house team to some areas of the UK. However, please note that this service has location restrictions and incurs higher costs due to the need for dedicated transport, making it more expensive than a standard RFD transfer.
