When you look for optical accessories, the Bulldog’s manual states this: “Use of 37mm tall (Absolute Co-Witness) rings, widely used with the AR platform, are recommended.” You may also use other sighting systems suited for AR platforms.

If you’ve always wanted a bullpup airgun, this is the one you should get! The Benjamin Bulldog in .357 is shrouded. That means this pup has a big bite and a small bark!

Not only is it a repeater, but it’s built with accessorizing in mind. You can put a flashlight, scope, bubble level and/or laser on your rifle and be ready for any situation that arises from dawn til dusk. In fact, any optical accessory made for the AR platform can be fitted to your Benjamin Bulldog .357.

If you’ve been looking for a compact airgun that won’t scare quarry after the first shot, get the Bulldog .357. Because this is a big bore gun, you’re no longer limited to smaller pests and game. One pest that’s destroying much of American farmland is the feral hog. And the Bulldog is a great tool for eradicating them. You can also take smaller pests and game at further distances than you would with smallbore airguns.

If you’re left-handed, don’t forget to order our service to switch the sidelever to the other side of the gun.
