I finally got a chance to tune my Notos to which I added the regulated drop block and a 250cc ait bottle. Initially the regulator was set around 160-170 bar but over a few months the pressure went to 200 bar. No other mods, not longer barrel, etc I added a heavier hammer spring. I can get a...

These are the main mods to my Niksan Ozark. Out of the box (before the mods) I did not like too much. After these mods I am starting to like it. After these mods, the only thing that could still be improved is the trigger. The accuracy was good from the start. Mods I added a cheap...

This post describes the main mod I am using to get longer flatter shot strings for unregulated PCPs. I use a finely tuned, 3D printed (from TPU) buffer placed between the valve and hammer. The buffer needs to be slightly larger than the inner diameter of the air tube so that it does not move...

Not even one week old and my JTS Airacuda Max really likes to inflate those balloons. The proof is in the photos bellow. For some reason the 100% positive youtube reviews do not show Airacuda's balloon inflating abilities. Those youtube reviewers don't know what they are missing.

I have just received my Airacuda MAX. I cannot remove the cap from the moderator adapter. I tried various pliers, heat gun, penetrating/cleaning fluid, etc Applying too much force with pliers would destroy the thread. Does anybody have any ideas on how to remove the cap? I sent an email to...

I had this PCP for about 2-3 years. I bought it new and I am the only owner. The rifle was only shot indoors and is in great cosmetic condition. I shot it this week and there was a puff of air coming out of the bolt area. Only when shot you have a puff of air coming out. There are no leaks...

Many of my PCPs started leaking after 2-3 years, usually after the warranty ended. The amount of time I spent trying to fix leaks by replacing o'rings is huge. Sometimes I succeeded fixing the leaks, other times I decided I had enough and sold the PCPs. PCPs (at this time) are the least robust...

I have installed the Huben regulator on my Notos. Discovered that it leaks through the small part in the photos bellow. I spent 3 hours trying various o'rings and nothing worked. The part has 2 grooves for o'rings at both ends of the thread. The groove diameter is 4.5mm and the total diameter...

I have an Umarex Notos and Zelos, both in .22 and both made by Snowpeak. The airguns are great, but the magazines are crap. The Notos magazines, do not align properly in the receiver and have to be pushed by hand into a position where the bolt can push the pellet into the barrel. One of my...

One of the magazines does not have any spring tension anymore and the drum inside the magazine will not turn. I assume the spring attached to the drum and the bottom of the magazine has somehow disconnected itself. Does anybody know how to fix this ? I cannot figure out how to disassemble the...

UPDATE Instead of the 9mm OD spring I started using the 8mm OD spring. The 9mm OD spring was rubbing against the hammer which caused inconsistent velocities, a 30-40 FPS spread. The 8mm does not have the rubbing issue. Original post I have got my Umarex Zelos .22 caliber a few days ago. The...

The same power can be obtained by less air but at higher pressure, or more air at higher pressure. How can you tune a PCP to be more quiet at a fixed power level?

No leaks and no mods unless mentioned in the post. The semiauto action was not reliable and I converted it to bolt action. In semiauto it would have issues with cycling the magazine or double feeding. It comes with: -2 good magazines -1 bad magazine (tape on top) -1 fill probe and o'rings for...

$100 + shipping. I will pay anything over $30 shipping myself, so the max you pay is $130. The air gun will be shipped from the Washington state. I have a Nova Liberty .177 leaking from the regulator/receiver area. This Liberty and an Avenger are the most accurate .177 I have. The Liberty...

My .177 Nova Liberty transfer port adjuster blew up. When I shot I heard a loud pop and the transfer port ejected the receiver. I never expected to have projectiles coming sideways :) The same transfer port is used in Nova Liberty/Freedom, Seneca Aspen and maybe a few more. Anybody knows how...

I like CO2 air guns as .177 pistols, lower powered and with lots of shots for target shooting. I prefer CO2 pellet (as opposed to BB replicas) pistols, and my favorites are Diana Chaser and the Crosman 2240. Diana Chaser is better all around than the 2240. I have tuned a .177 Chaser pistol to...

Nova Freedom .177 in great condition, very lightly used (less than 500 pellets). This air rifle was only shot indoors. It comes with all of the original accessories (shown in photos): -2 magazines -single shot tray -fill probe -front and rear sight -2 3D printed moderators (4" and 6" long)...

The thread with the subject "New Crosman 3622" has disappeared. My lengthy and well documented post has just disappeared. It might have been deemed too critical to the Crosman 3622. Was this thread deleted by an admin or by the original poster? How can one remove an entire thread, when the...

This is the Notos in pistol form. I printed the grips and the moderator insert. At 2 feet long, it is majestic and just a little nose heavy :)

I have added air bottles to a Benjamin Prod (see photots) and a Hatsan Jet. You can see the Benjamin Prod in these photos. The air gun needs to have a male Foster fitting, most USA sold air guns have that. You will need the parts in the photos: -90 degree Foster adapter costs less than $10...
