Umarex Brodax CO2 BB Revolver Table Top Review

No Comments

Type: BB air revolver.



Materials: Mostly plastic with some metal construction.

Weight: 1.3 pounds (586 grams).

Barrel: 5.5 inches, non-rifled.

Propulsion: 12 gram CO2.

Action: Revolver, single & double actions.

Ammunition Type: 4.5mm steel BB's.

Ammunition Capacity: 10 rounds.

FPS: 375.

Trigger Pull: The trigger pull on the Umarex Brodax CO2 BB Revolver is actually rather nice. If you decide to cock the hammer back and shoot it single action style then you get a little bit of that SAA Revolver like ratcheting sound. The trigger pull in single action mode is short with virtually no take-up and on the light side. Double action shooting with the Umarex Brodax CO2 BB Revolver is not overly long or heavy either so action shooting is totally possible with this BB shooting CO2 revolver.

Accuracy: I can not comment so far on the shooting performance for the Umarex Brodax CO2 BB Revolversince I have not shot it yet. The weather is getting nicer outside so that should happen pretty soon. The claimed FPS for the Umarex Brodax CO2 BB Revolver is stated at only 375 which I find seems a bit low for a none blowback fairly straight forward BB pistol with an almost 6 inch barrel so hopefully my testing shows performance up into the 400's which I am hoping for. The open sights are non adjustable but there are tons more options by taking advantage of the two rails top  and bottom for adding either a red dot or laser to increased target shooting ability.

Build Quality: The Umarex Brodax CO2 BB Revolver is pretty much an all metal pistol with the outer shell being made up of plastic, there is a fair bit of internal metal going on along with the trigger, hammer and of course the inner barrel made out of metal parts. Mechanically the Umarex Brodax CO2 BB Revolver feels solid and even though it only weight in at 1.3 pounds it feels much heavier in the hand.

Realism: The Umarex Brodax CO2 BB Revolver as far as I know is not an exact replica of any real steal gun currently in production. It's basically a spin off of an ultra tactical .44 magnum revolver with a super beefed up front barrel assembly sporting all kinds of accessory option to be placed on the top and bottom rails. I like that Umarex made sure to recess the barrel opening so it has a more realistic barrel size. Like many new CO2 airguns coming out these days the CO2 is not only well hidden inside the grips but a handy Allen key is built into the handle.

  • Not the heaviest revolver on the market but it feels really nice in the hand and has good balance, the weight is not bad at all and feels heavier than 1.3 pounds.
  • Trigger action is really good in both single and double action, short light single action trigger and totally usable double action trigger.
  • CO2 is well hidden with built in Alan key in the handle.
  • Rails top and bottom for all kinds of accessory add on options.
  • Barrel is recessed for that larger caliber look.
  • Nice and discreet safety.
  • Comes with three 10 shot easy to load rotary magazines.
  • Low cost with high fun factor.


  • Grips are a bit hard to remove to get at the CO2, may work-in over time?
  • All black sights are not great on dark backgrounds and are non adjustable.
  • Would have liked to see fps into the 400 range. 


The Umarex Brodax CO2 BB Revolver when I first picked it up did not appeal to me all that much, maybe knowing it was for the most part yet another mostly plastic BB revolver with those thin pop in disc magazines didn't help me take notice much. But as I have been playing around with the Umarex Brodax CO2 BB Revolver it has grown on me a lot. I think it has a really cool look that is also very usable in terms of putting juts about any accessory you want on this CO2 revolver. The hammer and trigger action are also both excellent for not juts an inexpensive Airgun but even a higher end airgun. And right out of the box, or should I say clam-shell plastic wrap, you get three rotary disc magazines which is a nice bonus.
