Umarex Notos CRK Review

[Firewalker]

I'm currently working on a cocking lever for the Notos, it's design is based on owner input and a design found on another moders post.

It will have an offset from the left side of the gun with a vertical post under the lever for easy access and clears the Carm hi-capacity mag.

I'm still in the design phase with a limited run of 25 levers. I should have the first one mounted this week.

Here is a mockup without the post.

Im working on the post for the lever right now, there will be a 20mm M5 cap head stainless screw bonding the post to the lever. More pictures tomorrow.

Cool, I'm thinking similar design....

looks like it will work fine.

Turns out my powder coat powder is too old and it overcoated, I'll buy new before doing production.

 I finally stopped shooting my Notos long enough to add the bottle adapter , I had bought way before I could get a Notos. I am using an AV regulator set at 2900 psi, so I am basically running it unregulated, with a suprising shot string, but was also testing the ability of the OE hammer spring.
 H&N 21 gr. slugs has been its favorite hunting round so I finished off a tin of them and started another one to see how far I could go.
 Hammer spring is 1/2 turn out from max.

 P.S. Does anyone know the OE hammer spring dimensions, or better yet a link to a stronger one that fits, asking for a friend

I saw the bittle adapter on Aliexpress.

Did you have to do anything to the adapter to make it fit the Notos ?

I am using a weaker hardware store spring that is a bit short.  Ordered an assortment of springs from China, but haven't tried any of them yet.

I used this seller for my 3mm CS x 305mm spring stock for my Challenger SSS experimenting.  They also have pre-cut in 10mm increments.  I bought the 2mmx22mmx70mm precut from eBay as well.  China 2-3 weeks wait but free shipping and cheap.  You can also do small quantities like 1 or 3 and typically no minimum order....

I like your string.  Looks like 2 CARM mags of 22fpe fun.  Is that slug a HP and do you think it will expand at 680-690fps or are you just thumping with 21 grains of lead?  Just curious...

Looks like I have come to the end of  my NOTOS/PP750 journey. Thanks to FIREWALKER and many others I have enjoyed the tinkering and mods to these pistols/carbines. I have the PP750 with the bottle mod and 16 inch barrel shooting 10.5 Crosman Premieres at 855 FPS .The NOTOS  .22 with bottle mod and 16 inch barrel doing 840 with 14.3 and the .25 NOTOS doing 780 with 20 grain pellets. All have side levers which I made from aluminum angle with hand tools. They also have custom made barrel bands from HOTSNOTS. I am now going to mod my ICONS  and see what becomes of them. Thank you to all who have contributed all their experience and advise. This is truly a great Forum to be a part of.

Pretty much just thumping the game with heavy wind resistant lead, getting pas throghs on most shots unless they transverse lengthwise, I do not try and take those shots.
