Webley MK VI .455 CO2 Shell Loading BB Revolver Table Top Review

No Comments

Type: BB air revolver.

Manufacturer:Webley & Scott.

Model:Webley MK VI .455.

Materials: Mostly metal with plastic grips.

Weight: 2.4 pounds. (1089 grams)

Barrel: 4.5 inches, non-rifled.

Propulsion: 12 gram CO2.

Action: Revolver, single and double action.

Ammunition Type: 4.5mm steel BB's.

Ammunition Capacity: 6 rounds.

FPS: 427fps.

Trigger Pull: Trigger pull on the Webley MK VI .455 CO2 Shell Loading BB Revolver is great in both single and double action, for a shell loading revolver the double action is the best I have come across with next to no friction like I would usually find with shell loading revolvers when shot in double action mode.

Accuracy: I tested the Webley MK VI .455 CO2 Shell Loading BB Revolver on my pool deck first off shooting 6 rounds through my Chronograph. The claimed fps is 427, I got really close to 400 fps in my testing so there is the potential for this revolver to shoot up into the low 400's. When I stepped back 30 feet and shot 6 rounds form my semi rested position, I got a really tight 1 inch group with almost all the rounds landing in the bulls eye. My shots where just a hair to the right but not by much which is good since the sights on this pistol are none adjustable. You can check-out my full Field Test Shooting Video here!

Build Quality: The Webley MK VI .455 CO2 Shell Loading BB Revolver is pretty much an all metal construction other than the plastic grips and any internal seals. The fit and finish is excellent with a great overall weight in the hand. The only complaint I have is that the grips being a thin plastic seem kind of low quality compared to the rest of this otherwise high quality Webley CO2 BB Revolver.

Realism: In terms of replicating a real steel Webley MK VI .455, Webley did a really great job with their CO2 BB firing version. Webley even includes a Small Arms Training Manual based off of the real steel variant. Webley based the BB CO2 MK VI from the original blueprints and the licensing is form the original 1915 version. The only real tell that this is a CO2 BB revolver would be the small safety switch on the lower right side frame and the CO2 valve located right behind the hammer.
