There is one Allen screw that holds the pic rail on. Under that is another smaller Allen screw that hold the barrel in.

[@mariosharidimou3508]

Thank you for that. Any idea on the average number of shots before and after the reg increase?

[@kidpellet6544]

I got 3 mags before and two mags after and I think it settled in at 23 fpe which isn't terrible for such a short barrel. Keep your eye open for the bottle conversion

If need to adjust your hammer spring just unsrew the stock tube much easier and faster then taking 4 little screws out

[@inkjnky1872]

Hello sir I went to adjust my reg today and when I unscrewed the silver part the regulator stayed in the tube do you by chance know how I might get it out thanks sir.

[@gman9543]

So did you back out your hammer spring until you saw a decrease in velocity to get the optimal use of your air?

[@kidpellet6544]

Initially there wasn't any real velocity change in the hammer spring adjustment at all. I suspected the hammer was already opening the valve all the way even on its lowest setting. This is because the regulator was set really low from the factory, probably to gain a few more shots. I backed the hammer spring all the way out then increased reg pressure until it lost velocity. Now when I turn the hammer spring up it actually increases velocity so I can tune for different ammo. It is currently bottled and using a paintball type regulator and 4500 psi carbon fiber bottle getting 100 shots per fill at 18.3 fpe. It gained just under a pound with the bottle conversion

[@justjoeoutdoors3499]

Appreciate the video, very helpful for the future if I decide to tune mine up a little..how much has it changed your shot count by adding that 1/4 turn on the reg? How's shot count at the high and low setting on the hammer spring? 🤔 I have lots of questions 😂

[@kidpellet6544]

Have not done a shot count yet. Just got done with the reg adjustment tonight.

[@kidpellet6544]

My reg was set so low the hammer spring adjustment didn't make any change in velocity. I turned it up a little and it actually had a little adjustment after that. Took the shot count down to about 14 shots at 22 ish fpe. It has a carbon fiber bottle on it now and gets 100 shots at 22 fpe. Weights less than one lb more than with the air tube

[@robl5455]

Is it possible to adjust the regulator the other way, to reduce the power a little? 15-17 fpe would be just right for me.

[@kidpellet6544]

On mine, the regulator was to low to get any adjustment out of the hammer spring. I know, it sounds funny but it needs to be turned up with the hammer spring backed off all the way. When it hits the right pressure it will slow down. If you adjust it only turn it counterclockwise a little bit at a time and test it.

[@mary0224]

I have somethingto ask have you tried a heaver hammer spring in the notos ? A lot of us dont have the courage to pull the gun apart to adjust the reg but the hammer spring would be a easy swap out to get some more fps out of the gun

[@kidpellet6544]

The spring g is an easy swap for sure. The problem is, the spring in my two Notos is already opening the valve as far as the valve can open. That's why there is almost no noticable difference in hammer spring adjustment. Most are finding that the velocity drops off right around 1900 psi. So 1900 psi is the general consensus for the factory regulator setting. I increased my regulator to around 2300 psi and was able to get and adjustment from 12 fpe to 23 fpe with the factory spring but had to add a spacer to the spring. What's important to note is that my shot count went from 3 mags to one mag. I'm positive this is why the gun comes setup the way it is. It has a fairly small airtube and increasing the pressure and fpe makes a huge difference in shot count. There are some "plenum kits" on Ebay that if nothing else increases the volume of air the gun holds and gives a few more shots. So far though no one is bragging about a big power gain. Also, a few people in the Notos FB groups reported less that ideal threads and even chips in the plenum kit they got from Ebay. I dont know if your in the Notos FB groups (2) but there are ways to bottle these things and one guy that is offering to do the work. I bottled mine with a small carbon fiber bottle and at a factory 18 fpe it's getting 100 shots on the regulator. I put a little bigger bottle on it for an iguana hunt and didn't refill it the whole trip. The carbon fiber regulated bottle and adapter will run about as much as the Notos itself though. Maybe join both groups to see what people are doing. I'm in both as Ray Barnett and would be glad to share what I've done to mine so far

@@kidpellet6544 Ok the springs in your Notos are fully opening the valve but if you put in a bit heavier spring the valve will open faster and stay open a bit longer therefore making more fps & fpe ! You said that you put a spacer in one of your Notos hammer springs isn't that the same thing as using a heavier hammer spring ?? Both the spacer & heavier hammer spring would preload the hammer spring !!

[@kidpellet6544]

@@mary0224 yes, the spacer and the hammer spring being cranked up to the point of coil bing. Any more and the gun wouldn't cock. I did this for more power along with the regulator turned up to around 2300 or 2400 psi. I don't know the math on it but at some point I expect the pellet to be out of the barrel or nearly out of it before the valve can close. I'm certain in my case I was wasting a lot of air as it only got one mag before it fell off. It also didn't group as well at 30 yards. Not sure how far out I tested after that. My intentions were to get a little more power for 30 yard squirrels. I settled it back down to 18 fpe with 18 grain pellets and it shoots around 3/4" at 30 every time. Not exactly a target gun but plenty good enough for what I want and with even the small carbon fiber bottle it gets 100 shots at that power. Need to make a video on the conversion but I was waiting until I get my new block design finished before I disassemble it. Maybe help others out that are on the fence about mods and such

@@theobserver9565 the trigger screw will not do anything for fps. Turning the regulator screw out a little more with the hammer spring backed out all the way will increase the fps to a point then start to decrease the fps. At this point you can turn the hammer spring in all the way to increase the fps. This will give you the most adjustment up AND down for tuning light and heavy pellets without modifying the airgun

[@chrischattergoon47]

You think it's possible to put a like a 300cc carbon fiber bottle on this ? Or will you have to do too much modification.

[@kidpellet6544]

I have one on mine now. I made a custom offset adapter. Am working on several more. I think I put a 220 cc bottle on it and got 100 shots on the reg at 18.3 fpe. Weighs less than a pound more. That's not bad for gaining 80 shots per fill

[@mrhalfstep]

If you shot the gun over a chrony and noted the point where the velocity dropped off and then read the gauge on the tank, wouldn't that be pretty close to the reg pressure setting? Maybe record the pressure before and after each shot to nail it down a little more accurately, but it seems that it should give a good ballpark feel for what the reg was on, wouldn't you think? If a guy didn't have a chrony, I bet he could shoot some pellets at long range and note when they suddenly dropped in elevation on the target. Using really heavy pellets would probably make the drop more obvious and sooner, seems to me. What do you think? I guess if you had a gun with both gauges you could test the theory, if you just wanted to find out. Might keep you from messin' with installing a second gauge.

[@kidpellet6544]

It would be close enough but in my case I would want to know what I'm setting the reg at before I reassemble it

Marauder pistol or notos? Which do you prefer? My prod is accurate ans quiet with a sumo.

[@kidpellet6544]

I have both though not equipped with the same scope. Oddly enough my Marauder pistol is all stock still???? while my Notos has a custom bottle on it now. I love all my Crosman/Benjamin stuff and have a couple of custom builds that are fantastic, however, stock Marauder pistol vs stock Notos, the Notos wins hands down. First, neither one is an extreme benchrest contender. More of a great 30 or 40 yard pesting/small game rig. With very similar accuracy and power it's my humble opinion there isn't enough difference to say one is hands down better than the other in that area. The Notos will indeed get 20 shots on the reg but doesn't seem to have as good a barrel as my Marauder pistol. The Marauder pistol I have will shoot really good for 10 or 15 shots and then needs a fill before poi starts to move. The fact that the Notos has a regulator, and I don't know of anyone reporting reg creep or total reg failure is great. It also has a side lever, which isn't as important to me as some others. The fact that the Notos comes with a fairly comfortable adjustable stock and the Marauder pistol has to be purchased as a kit or ordered separately, and costs more is another strike. Then there's the cost, most Marauder pistols I've seen lately are north of $450 without the stock which I believe are around $40, it's not adjustable or all that comfortable, to me anyway. The Notos, for the time being is still around $270. That's a lot of features for that price no matter what brand. There's also a custom Carm magazine for it, a couple of custom bottle options so it has enough interest that the aftermarket world is already on it. So I would definitely get a Notos over the Marauder pistol, probably going to get a lotta hate from the Marauder fans😬

Not to adjust it. If your going to start disassembling parts of the trigger/receiver your not familiar with then I would degas just for safety. Generally though just turning the screw located in the trigger itself clockwise will take up all the slack. Take up to much slack and it will become a hair trigger. Back off just a little and it will be pretty good. I put a little thread lock on mine so it stays put.

@@slicktmi a half turn is a lot. If you dont have a chronograph try this. Fill the gun, shoot it at a target at 45 ish yards.

This is roughly the regulator setting. Most are reporting 1900 psi. If you got the plenum kit from Ebay I think they come with a hammer spring spacer. Install that, turn the adjuster in as far as it will go and still cock. Then turn the reg up about a quarter turn. Repeat the shot string and see what pressure the poi drops again. Confirm it again and decide if you want to go more. You might be able to get some chronograph help from a local paintball or archery shop. You might have to bring your own backstop.
