Benjamin Mayhem NP2 SBD

the windage notch pivots as the other reviewer stated. it relies on its proximity to the bracket piece on which it mounts to stop it from pivoting. if its not butted up tightly then it pivots. since there's a little gap it constantly pivots and wont maintain adjustment. the only fix i see is to jam some kind of a shim in there to keep it tight. super cheap design. the sights were one of the reasons i bought it too. not happy it has to be modified to work properly right out of the box.

I bought this with the intention of shooting pests around my home...well they are still there. This gun leaves a lot to be desired. Pros - Cocking is a breeze, and this thing is silent. You hear the piston firing next to your hear so it sounds loud. But if you are not next to it, it's a soft pop. Cons - The biggest set back is the trigger. Even after installing and aftermarket trigger spring and set screw to lighten the pull it's still stiff. The heavy trigger just takes all the fun away. Concentrating on pulling the trigger while maintain your target is cumbersome. Grouping is also not all that great. I have a Leapers fixed 4x, and I cant manage to pull off a group better than 1" at 25 yrds. For me, that's not acceptable. And no, this isn't my first or even second springer. If you just want to shoot cans in your back yard its a great gun. Pest control...not so much.

love this gun...now the bad news scope was junk right out of the box rear iron sight broken as well but crossman is sending new scope and iron sight for free...plenty of power accurate as h*ll !! shoots crossman 14.4 gr. and h& n sniper 17.90 gr. exactly the same dime sized groups at 25 yards have not shot on paper any further than that yet...i put a cabelas 2x 7x32 ao airgun scope on it and its great!! love the stock and weight of the gun very comfy to shoot cocking effort is not bad at all... pictures really dont do justice for this gun i watched videos on youtube and that was a lil better...airgun depot did a great job and i would like to say thanks alot to Kenny Kormandy of myairgunreviews youtube...i was looking at a few different guns in the $200 range after i watched his review i bought it!!!!! lol....sorry if i spelled kenneys name wrong.. only 4 stars because of bad scope and rear sight

Pros
very quiet...power

Cons
noe so far

On receiving this airgun today, I opened the package and examined the basic mechanisms. I have no experience with break-barrel air rifles, so have no metrics for comparison, but here goes. The Silencing Barrel Device section on the barrel is plastic baffles (whether fiber-filled or not, I don't know) with a fairly thick aluminum shroud, and a plastic cap. It appears to do its job to my satisfaction; this is quiet to shoot, to me. The long SBD shroud prevents using a laser boresight, though that's mostly convenience (and ammo cost, and headache). As visible from the pictures, it has a front loop for installing a strap, though you need to install your own loop on the rear post to complete a strap installation. The center of balance is right at the ridge of the front part of the stock, just where the curve of the stock changes from the visible downward angle to being parallel to the barrel and piston housing. It weighs 7 lbs, 7.5 oz without the scope, and 8 lbs, 11.8 oz including scope and rings (and scope optics covers). The front iron sight is a basic blade sight, molded into the SBD cap, so is not simple to alter or replace. The rear iron sight (notch) seems... less than useful. While it has adjustments for windage and elevation, the notch isn't held steady, either to the barrel, or to the windage screw. What I mean is that the notch pivots up and down along the axis of the windage screw, and the notch base is bolted to the barrel (with two Torx/Hex machine screws) rather loosely. This flaw is NOT visible to me in the pictures I've seen. Setting it for windage and elevation, therefore, could be somewhat futile, as the notch could shift by a degree or two up, down, left or right between shots. I don't see any utility to having the notch move that way, and while the base can likely be tightened down, I've seen no way to stabilize the notches blade. I feel like Crosman/Benjamin said 'You want iron sights? Really!? *Sigh* Fine.' and just slapped something together. The existence of the iron sights themselves was one reason I bought this over some other guns I had my eye on, so this kinda stinks. I'm waiting 'til I can break in the gun (no more dieseling) before installing the scope, but as I'm quite new to scopes, I'll likely not have much to compare it to. Would've been nice to be able to use a boresight to get started sighting that in, but I might eventually muddle through it. Possibly I'll make/find an extender for the threaded post that attaches to the bore holder, so I can get it past the baffles. Overall, the gun seems sturdy, and if it lives up to its ~800fps reviews, I'll be happy, but the little things are getting to me as yet. If I can edit this review, I might later, or review again later when I've had a chance to use it some more.

Pros
Seems (mostly) well made. Quiet. Great sale price.

Cons
Front blade sight not replaceable (barring modifying the SBD cap). Rear sight loose in 2 places, seems to need replacing to fix one of the loose spots. Can't use 3.5" boresight.

I purchased this weapon based mostly on a combination of Looks and Hype over the SBD/Silencer add-on to the barrel. It makes a noticable difference to me, however the rifle is still louder than I hoped it would be. I purchased mine in .22 caliber and have run 4 different pellets/weight classes. Would recommend to buy this if you find it at the $200 price point. The gun does not look as awkward as I assumed with the extra large barrel silencer - it looks way better in person than in the picture in my opinion.

Pros
Pretty Good value brand Very accurate Fits my extra large size hands Scope that comes with is good, however would definitely recommend upgrading if doing more than backyard plinking

Cons
louder than expected - not a massive difference over other air rifles in the $200 price range. Scope works, but is mediocre.

Overall, I'm just satisfied enough with my purchase to keep it. I bought this gun because I moved to a neighborhood where my plinking adventures need to be stealthily quiet. With that, I wanted something quieter than the Umarex Octane - that I love. It also has a gas piston, but with a loudness rating of "3 - Medium," so I was all excited about the "2 - Low-Medium" sound rating for this gun with the new and much-hyped SBD. Turns out there's not much difference in the noise level between the two, and the sound meter says so...

Pros
This is a great looking gun. It's easy to shoulder and the SBD getup at the muzzle is not nearly as odd and clumsy looking in person as it can be in pictures. The cocking force is surprisingly light, and the SBD quiets the report down to acceptable levels for neighborhood shooting. Your neighbors will still hear it. It just shouldn't be loud enough to disturb them. I'm still in the break in period, so I'm satisfied with the 1" groups I've gotten with several different pellets at 15 yards.

Cons
The trigger is a step up for a Benjamin / Crosman break barrel, but that's not saying a whole lot. I'll play around with the adjustments a bit more to see if I find a setting I truly like. I bought this gun in .22 caliber, and it comes nowhere near the advertised velocity and energy numbers. The best I've seen is a 14.3gr CPHP at 800 FPS - around 20 FPE compared to 26 FPE advertised. That's about 23% short. Of course, seasoned airgunners are used to this, but it still sucks no less. That must be a function of the unexpectedly light cocking force, which all factors into meeting the primary selling point of this being a relatively quiet gun. There are several other options available that match the sound level and accuracy of this gun, although they may not be as good looking. Some of them do that while exceeding the power this one has. Since this gun costs as much as $100 more, I would only recommend it to a friend with an *asterisk*. The good news is I think this is the last airgun I'll need. I think... 8-]
