New from Benjamin, the Mayhem SBD is a breakbarrel with a lot of attitude –but not a lot of noise. From its sturdy stock to its quiet shots, this gun is ready to drop targets and small game with style.

Loaded with features, the Mayhem includes Crosman’s all new SBD technology, a modified suppressor that makes this gun 3x quieter than other suppressed breakbarrels in its class. The asymmetric SBD (silencing barrel device) is designed to keep out of the way of the included 3-9x40 AO scope, a step-up from the optics included with its Trail and Rogue lines, and mounts on the Picatinny/Weaver rail. For easy cleaning, the SBD suppressor comes apart with a single screw. If you prefer to go without the scope, Crosman included a front post and an adjustable rear sight for those who want to put their shooting skills to work.

Designed with the shooter in mind, the Mayhem’s soft touch synthetic stock features multiple textured handholds for an easy grip, with integrated sling mount and included sling for field carrying. Crosman’s Nitro Piston technology ensures that this gun will be easy to cock, shoot straight in cold weather, and not vibrate when you pull the trigger. The Mayhem also sports an adjustable 2 stage trigger, so you shouldn’t have any trouble getting a smooth pull. As if all of this wasn't good enough, this airgun is assembled by American workers in Crosman's manufacturing headquarters in Bloomfield, New York!

All of these features add up to a stocked airgun that’s going to give breakbarrel airgunners everything they could ask for!

Things I liked: This gun blew me away after i cleaned the barrel and mounted a UTG 3x9x40 scope and UTG 1 piece 1" high UTG mount I finally found that the JSB Exact Diabolo .177 8.44gr were outstanding and very accurate at 25 yards, also the Polymags were very good as well very accurate!

Things I would have changed: Not much good .177 for the money.

What others should know: Its a little heavy for a small kid,This gun is hold sensitive i needed to place my left hand on the front screw holes and bring the rifle tight to my sholder but then it was dead on shot after shot,This gun does not like to be shot bench rested without that hold.
