it’s fully ported and the barrel port is elongated and angled to about 45* to direct air flow down the barrel. i admit i did spent about an extra $140 on a drop block and plenum but that’s it 😅
stock barrel, half coil cut off of the hammer spring,trigger job, stippled the grip i lightened the hammer. moderator with a 6.5mm exit hole.
reg at around 2100-2150psi. my wife and i just bought a house. i’m too broke to spend more money on a $250 dollar gun but i did buy a K1 from a member here to act like bedrock and stop me from digging too deep into that rabbit hole called power.

Enlarging various air holes :) usually will get you a small velocity increase (20 FPS?).
A lighter hammer may help with efficiency, not with power.
I have the regulated drop block with the regulator set to 2300 PSI.
With no other changes I get about 750-770 FPS with CPHP, almost like stock.

How did you get to that power?

A longer barrel would explain the power, but you said you do not have that.
Is the plenum the main contributor to that power?

You get 850FPS with 15.89 grain pellets.

Let's assume that what you say is the truth.
In the best case you spent $300+ to get you there, longer barrel, plenum, whatever.

If I wanted that power, I could get it for $300 in a regulated rifle (plenty of choices).
For less than half the price of your "upgraded" Notos.

The Notos is a great short range plinker/target shooter.

Some people really like making a $230 air gun into a $800 air gun.

lol my notos is dope, truth.. a .177 p35x would be nice too.

some people really do like making a $230 air gun into an $800 air gun. not me. i have a lot of respect for those people cause those people are usually the ones leading the front lines of our rabbit holes.

i have the stock barrel. i’m too cheap to do a barrel swap and i like the length that the notos is currently at.
i would say yes, the plenum added with the porting and stock regulator settings from the airtube brought the gun up from 770-780fps cphp 14.3 to about 850fps with the same 14.3.
i only cut the spring so i can bring the fps down when i wanted to lower fps. the stock spring strength didn’t allow any fps adjustments up or down.
i did change the breech O-ring and the 2 barrel o-rings out, but those were items i had on hand.

Was gonna say I love my vulcan 3. Take 90+ yard shots consistently...only drawback is not externally adjustable and I like messing around with different size slugs so next pcp will definitely be externally adjustable. Here's my favorite 90yd+ shot. Shooting a heavier slug now than what I used in the vid....62.5gn @ 945fps / 123fpe

I owned a Beeman Raider for 2hours but I returned it because of quality control issues. First the open sights were unusable, rear sight was canted to the left side and front sight to the right. I was able to move the front of the barrel shroud to straighten the front sight but nothing for the rear ( had a 2 piece shroud). Installed scope , ran out of left adjustment before hitting the center of the target (1.25 inches right @ 25 yards)
Returned it to the store. Inspected the 2 more they had sights were worse than the one I returned. So, cheap yes but even at that price it should be shoot able. It grouped decent, nickel sized so I will give it that. Just not what I wanted to give my daughter for her first pcp gun.

you have more info on these changes? I'd like to be at around the 850 fps mark with mine.

I finally pulled the trigger and got mine. Paid for that 24 hour leak test and the 10 x 10 shot test by pyramidair as well.

i was able to get 705-710fps (27fpe)using .25gr with the stock air tube and stock barrel from a plenum and porting alone. i opened up the airways for parts —#42, #40, the barrel port, and the hole that part #66 screws into. i can’t remember what size i expanded those to but it was as big part #66 hole was. for the barrel i elongated the hole so i can increase airflow without having the pellet fall or get stuck. i also angled it to deflect the air directly behind the pellet.

I don't think the Marauder can be beat, and a used one is easy to find. They're the 10/22 of airguns. They can be had for $300.
The Notos is a great gun also within your price range.
My pal has an Avenger, near that price range, and it's amazing.

I like that and agree. The Mrods are the 10/22 of the airguns
The OG. They are awesome but a little heavy and long

Guilty, But I do appreciate them as designed for a few minutes first LOL

Beeman Raider
Click to expand...
I have a Beeman Raider in .177 and one in .22.
Each were around $120-$125 shipped.
They are quite accurate at 50-60 yards.

I bought them for the low price and the challenge of tuning unregulated PCPs with small air tubes :)

I added the valve hammer buffer (AKA Bstaley mod) to both.
These are the tunes I have for them

Raider .177

Pellet: Norma domed 9.1 grains
Pressure: 3800/3900 PSI to 2500PSI
Velocity: 840-863 FPS
Shots: 50+ (4 mags + some extra)

Mods
Valve hammer buffer (BStaley)
Height: 2.90-2.95mm, OD: 22mm, ID: 12mm

Raider .22

Pellet: CPHP 14.3 grains
Pressure: 4000PSI to 2600PSI
Velocity: 685-712 FPS
Shots: 60 (6 mags)

Pellet: CPHP 14.3 grains
Pressure: 3800-3900PSI to 2700PSI
Velocity: 692-712 FPS
Shots: 40 (4 mags)

Mods
Valve hammer buffer (BStaley)
Height: 2.5mm, OD: 22mm, ID: 12mm
