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 gas springer is powerful, and very accurate, especially with the right pellet. Mine seems to love the H&N Terminators, and the H&N Super Magnum. These heavier grain pellets match up very well with this gun. Crosman Destroyers did okay too, but not nearly the accuracy of the 2 mentions H&N. At 20 yards I can achieve dime sized groups. Alloy pellets are too light for the muzzle energy this rifle has, So the spread of the groupings are 3 inches or more. The Mayhem throws those light pellets all over. I like the fact that this model is assembled in the USA. The 3-9x40AO Scope (included) is very clear, and really good quality for this price point. The rifle is heavier than I expected, with about the heft if a shotgun, but that is not a bad thing. It is a quality gun. I purchased this Benjamin Mayhem because of a nuisance raccoon problem I was having. (A problem I no longer have thanks to this gun, a steady hand, and H&N Terminator pellets).

Things I would have changed: The trigger breaks at around 5 lbs. this is just fine for most shooters. I ordered a spring kit from Mcarbo (made in USA and cost about $20 bucks) and brought the trigger break down to 1.5 lbs. Just a personal preference. It is a very easy upgrade and they have a step by step video to help you.

What others should know: I believe the Benjamin Mayhem is a great value for the money, and I am having a lot of fun with hours of target practice. Spend an additional $26 for a Caldwell Shooting bag combo to hold up the rifle for you if you plan on hours of target practice, for this gun is hefty. My son and I are having a great time shooting together. We are very happy with this purchase!

Things I liked: Almost everything. (.177; nearly 500 pellets) VERY Quiet, comfortable, Powerful, and reasonable recoil for so powerful a "springer". Easy to cock and no worrying... did I accidentally leave it cocked for hours! I also wanted it for cold winter use and no spring. The scope is way better than anticipated. I bought this model because it had the better scope rather than the Benjamin Trail NP2 as offered. Well worth it. I went on line and learned all I could about this series of guns and that made a difference including not only expectations but how to get the most out of it. Thus far I've used 5 different pellets both in weight and brand. It will literally zero with any of them, but the H&N Barracuda Match does stand out (superior manufacturing certainly helps). The H&N were far more consistent. Now I'm hitting a quarter @ 45 yards depending on wind. I do not have room to extend further at this time. The grips are soft and give a good hold. Balance is typical of this type of rife.

Things I would have changed: It weighed in about a pound heavier (8.5) than advertised and I don't think that is just the scope. The rear hard site was loose and fell off after one evening of shooting. The front site seems to be plastic and 1 bump made a mark in it. This gun definitely took way more pellets to get a proper handle. In my case a couple patient, it is worth it. Now I know how it behaves with 5 different pellets of differing weights and brands. That was part of my travails. Yes, they are very different but I put up a 2x4 foot board with many targets and learned each characteristic (I do not have a reviewer's setup).

What others should know: As one of Pyramyd's videos suggested, it does shoot best with the front hand under the fore stock. It did take time and patience to get it "right". My other 2 springers are less powerful and I expect less of them (cans). I was finally able to get the Crosman Premier Ultra Magnum to be accurate enough to plink every time. However, those pellets are tight, loose, and all in between. Considering this I was amused that I could use them reliably on cans. I wanted a cheap pellet for plinking. I am still learning the AO and just how accurate that is. The scope needed lock tight to stay in place as this is still a "springer" though gas. All in all I would definitely buy it again.

  • Fin from USA asked:

    Does the Benjamin Mayhem NP2 SBD Air Rifle Combo include the same scope as the Trail NP2 Combo upgrade (CP394AONP2-999)? Also, the Crosman web site shows the scope raised up higher than the photo here. One Youtube review said the front lens cap won't go on. Which comes with this package, low scope rings or higher?

    • Matt from USA asked:

      Is it quieter than the NP2?

      • Chevota from USA:

        I would say no since the shroud has been removed. I'd even wager it's louder, but I don't have one so I can only speculate.

      • Stanley from USA:

        This also has the NP2 installed .

    • Cole from USA asked:

      In .22 calibre will this gun dispatch a skunk? How quiet would it be compared to my Grizzley spring operated break barrel?

      • Stanley from USA:

        Yes it will . The NP2 will be somewhat quieter than its spring operated counterpart.
