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 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 and sling mounts 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: The gun is what I expected and more. It is quiet right out of the box, once it holds a nice tight pattern with solid impact. I currently have a RWS Diana .177 it is also very good gun but it was lacking the impact I was looking for to thin out the woodchucks in my garden. That is the reason that I bought the .22 Mayhem.

Things I would have changed: The rear adjustable site is very loose and the scope is not as friendly as advertised, but for the money, its an overall good value.

What others should know: This is currently my second Mayhem because I ended up returning the first one within the 30 day warranty period. The reason for returning the first one is that the rear site was so loose, there was no way to tighten it up, the scope was also faulty to the point where I couldn't hold a 4-inch pattern at only 20 yards. The trigger itself was also very hard to pull, it felt like the working mechanism was never polished because the entire pull felt very rough, even at the highest hair-trigger setting. The replacement gun that just arrived is a whole different animal. Its got a very smooth trigger pull; the scope is better but the rear site is still a little loose. I decided to switch to scope out for a red dot quick acquisition scope which I now have dialed in at 30 yards holding 2-inch patterns, it is by far the best way to zero in on a critter in the garden and take it out quickly. I am sure that the .177 is also very good gun, but I'm very happy with the .22

Things I liked: How quite it is. I live on 5 acres so not that important.

Things I would have changed: I did not like the scope, so I took my other scope and put on it.

What others should know: Had to try a lot of different pellets to find what it liked. Had to adjust the trigger pull down so it did not jerk so much. It is heavy, so I have to have a rest to shoot good.

Things I liked: The Mayhem hits plenty hard. I have rock with a flat face leaned against a tree in our backyard woods. At 20 meters the .22 caliber Crossman Premier pellets completely flatten (completely!). Took a while to get the included scope mounted and anchored, but when finished it shoots better than I can at the moment. That will change with more practice--and will an economical air rifle, you can practice and practice without bothering anyone--it is quiet. Always have an extra strong backstop for target shooting with the Mayhem or its immediate family of Benjamin rifles.

  • Gary from USA asked:

    The trigger pull seems to be a bit much. is there anything I can do to lighten it up?

    • Gary from USA asked:

      Anyone have experience with the .22 between 75 and 125 feet regarding accuracy? Is there a graph of pellet drop at different ranges anywhere?

      • Mason from USA asked:

        This gun is super loud and I need something quieter but I keep reading comments on how quiet this gun is and I am beginning to think that it's something wrong with just my gun. Is it because it's new or could there be something wrong with the suppressor?

        • Chad from USA:

          Three possibilities come to mind. Your pellet is too light like said before. Possibly it's still in the break in period. Benjamin says to put 250 pellets through it then everything is smoothed out enough to find out what pellet it likes. Lastly you have a oil residew in the barrel or chamber. Oil combusts under the firing pressure giving you a speed boost and eventually damaging the gun. I gut the .22 and with 14.3gr pellets it is as loud as loudly snapping fingers and the impact on wood at 40 yards is twice as loud. Out of the box right behind the scope it was 83db! I don't think you'll find a quiter break barrel. Good luck

        • Tyler from USA:

          Yes, use the heavier pellets. It's likely that the lighter weight pellets are breaking the speed of sound (around 1100 fps) which produces a crack noise when you shoot. The heavier pellets will slow the gun down to a velocity that is below the speed of sound and that should show you just how quiet the gun can be

        • Mason from USA:

          I got the .177 gun. I used the Daisy .177 Precision Max 4.5mm and they are 7.2 grain pellets. It's what I had at the moment and I just got Gamo Silent Cat pellets that are 10.5 grain and I also got Crosman copper magnum pellets that are 10.6 grain. So you're thinking the heavier the quieter?

        • Tyler from USA:

          Do you have the .177 or .22? If .177, what pellet weight are you using? Maybe you're breaking the speed of sound and that's why it seems loud to you?
