The following was performed on a heavily modified 25 cal marauder.

I got around to testing my new balanced valve in my marauder, it is a drop in that replaces the end cap, however this version uses a 2mm valve stem so requires the stem bore be sleeved down. The poppet is made from peek (very fun to get sealed with only 60 lbs of force holding it shut) with a balance ratio of around 60% (60% reduction). The valve stem 2mm bar stock that I reduced to ~1.3mm within the area of the throat, as I always do, this is because I run a .234" throat that support .225" porting ahead of it, which works well with the 1.3mm stem. I have yet to have a stem fail in the 6 years I've used them. Enlarging the throat would require more hammer strike and my build has always been oriented around reducing this as much as possible...so here I am, taking the extreme. DYOR and do so at your own peril!

With the pictured hand made poppet/balance valve I was able to reduce my hammer weight to 14.8 grams, while using only a 7 lb/in hammer spring to reach my valves plateau of ~60 FPE when set at 2000 psi (pretty typical power for a marauder at this setting). The prior valve, same setup but with a 3.175mm valve stem required 18 grams of hammer and 9 lbs of spring to achieve the same power.

The same 14.8 gram hammer with 3 lb/in spring with minimal preload sends 8 grain pellets in .177 out flying at 850, iirc the other 3.175 stemmed valve could only do about 650-700 fps with this spring fully preloaded.

The valves chamber height is adjustable (adding volume allows the valve to open easier, taking more time to fill the chamber, reducing volume does the opposite), but I try to keep my vent and chamber volume harmony to a point where I can tune within my desired range, down to 12 ft/lbs in .177, up to 60~ fpe in .25 cal.


One may ask, why do you still bother with the old marauder, to which I reply, marauder may be old and dumb, however I am young and dumb, and the marauder is a good gun to learn on, and boy have I learned! Prior to running the balanced valve, this gun operated just fine with a 52 gram hammer and the same 7# spring, but I like tinkering, and the result is a gun that operates with very little vibration in the frame with the lowered hammer energy requirement

52 gram hammer with 7 lb spring lock time = 7-8ms
14.8 gram hammer with 7lb spring lock time = 4.3ms

The reduced lock time and vibration in the frame which resonates thru the gun prior to the pellet leaving the barrel definitely doesn't bother me! I may even reduce the weight more...because I can't leave things well enough alone, ever. Thanks for reading.

Poppet OD: .3"
Balance chamber: .234"
Vent diameter: .038"

Well i guess it’s time for me to post a short review ( im not much of a writer) of my 2 ghosts as I’ve had them for about a month and have shot my first ft match with the 177 hp. The 177 shoots 13.4 jsb mrd’s superbly thru its poly barrel, i actually like the way it handles especially standing better than my red wolf. The trigger leaves a bit to be desired as franklink noted in his review the only other thing i wish was different is with the hp the hammer adjustment is useless and you need to adjust velocity with careful adjustment of the reg. 81 bar and min on hammer is bringing 810-815 fps and as i said it shoots very tiny groups with weighed pellets.
Now for the 25 - what a machine! 50 yd groups 1/2” and tighter off styx! 100 yd groups with weighed pellets and slight breeze again off styx run 1 1/2”- 2” so if its calm and your locked in a rest probably extremely good. Adjustability of hammer spring is ok but its not a m3 but again i like the reg adjustment much better than the m3 as it can be adjusted to a fine degree easily without tools. Are these guns perfect? No but they are pretty damn good and you won’t drive yourself crazy trying to tune them they are very easy to get good shot count and really good accuracy!
Now i bought both guns myself the 25 from atlas airguns and ordered the 177 hp from aoa which took a bit over 3 months to get. Im not paid by anyone for this but after having the guns for about a month im impressed and happy. Oh finished tied for 2 nd in the ft match on a pretty breeze day and after making a few mistakes I don’t think ill be making again!

I was reading this blog from a guy that posts a lot of them on tuning (almost as many as pa blogs) , but this hw he was doing in it on the mainspring he used copper antiseize . Now like most i guess its been a moly or now that krytrox ..

So anybody not in a pinch or common practice used the copper antiseize on just the spring ?

P.s
Not globbing it on but a nice thin coat

I’ve never seen anything like this. That kid might be “The Guy” in about 15-18 years. It seems like mom approves. I thought I heard a woman’s voice behind the camera. Love the family dynamic in the hunt.

I have a .22 leshiy 2 with a 350mm barrel that has been custom threaded for 1/2x20. It will come with one mag, 350cc bottle, wika reg guage, Valkyrie aluminum handguard, fx shroud that goes over and mounts to the barrel, and a Huma-Air Raptor Tuning Regulator. Your choice of grip if you want multiple I will add for a fee and will come with a hugget belita for $2200TYD only trades I would consider are .30's nothing specific yet so let me know what you have.

Please know that I’m only shooting at this distance for the fun factor. Using 10 MILs of holdover, I can see the pellet drop down from the top of the objective as it hits or misses the intended targets. Today I got three hits on five attempts. Of course wind conditions have to be just right. But in real practical terms for pesting, this little demon is murder on small pest out to 60 or more yards in a good shooters hands. That saline bottle is the size of a chipmunks body.

I have a brand new cvlife bipod and scope for sale. The scope is a 3-9x40. Asking 35 for both of them. Won't come with the rings on it, but will come with the rings that came with it.

If your was to shoot a different airgun you own every day. How long would it be before your rotation of starts over?
Estimates are fine.

Been about 6 months since my last tree rat, guess I did a pretty good jobs keeping these roof eaters off of my roof! Speaking of the roof another neighbor has been spending thousands repairing his roof damage from them and water damage from the leak.

Today was the first hot day, shot straight to about 85 by noon. I was messing around with some stuff and saw some movement in my tree, ran to my garage and grabbed my trust dream-tac compact loaded with hades. To my surprise it was still on my tree because last couple of tree rats high tailed out of my yard as soon as they saw me, guess this one didn't see the Facebook post about my yard! So I put the center dot on its vitals through its shoulder and squeezed the trigger. Solid thump, like normal it tried to climb the tree but couldn't, it came back down but it was behind the tree so I couldn't see it. Usually they pass out about 5-8 feet from the trunk. Just as I was about to go over there it appeared at the based of the truck not dead! Guess my shot wasn't good enough so put the dot between the eye and ear and thud again! This time it did the death flop for good 15 seconds, I thought it would ran out of gas long ago.



It was an older female, pretty good size. Tried to find the pellet as usual and I was really shocked by how that thing isn't dead from the first shot, the 177 hades pellet was more deformed I have ever seen, must of hit all the bones.


Then I found the headshot pellet too, it didn't pass either like usual so this is definitely one really tough tree rat, maybe toughest ever for me!!!

I was looking over some of the site functions and got curious when I saw the “current visitors” tab. I was wondering, “how would AGN know who these people are?” When I clicked that tab many of the visitors just said “Guest” where a username would be. BUT I also noticed bots that were combing the threads. Some of had huge tech company names attached to them and others had names I’ve never heard of. I clicked one of the bot names and it started to take me to another site. I closed that tab.





I don’t know much about bots. Can any members or staff explain their purpose here? I would imagine some are the result of people using search engines, but what about some of the other ones? Are any of them malicious? Is there a way that we can differentiate one from another with relative ease?

Selling as one lot. $125 shipped CONUS PP F&F or buyer pays fee.

H&N Baracuda 18 3 sealed tins
H&N Baracuda Match 21.14/5.52 5 sealed tins

Polymag 16g 4 tins not sealed but appear to be full

So just wondering how many members here respond to these adds? If so what are your results, as for mine it is a waste of my time.

I need to know if this is okay to use its secolube 500 Its only been in there 15 minutes but its this dark WHATT??, I though the first oil change gets all that stuff , How come only 15 minutes in an my secolube is that dirty is it alright to use despite the color its only 15 minutes old.

With the long list of EBR podiums credited to the Impact platform (not necessarily the M3, though), I was quite surprised at how much mush there is on the second stage.

Don't get me wrong, it's on OK trigger...for a bullpup. But certainly not what I was expecting given that podium pedigree. Not match-grade by a long shot, IMO.

So what are you all doing to get a cleaner break?

Hello, its was time to clean the barrel of my Maverick. The screw for removing the barrel is stuck in the shroud. Any Idea's to remove it.
Sorry for my english.

Hey guys. I got a Panthera and now I'm learning to tune it. It's not a straight forward thing. There are different ways to arrive at your desired FPS. I was struggling, but got some good insight in this thread: https://www.airgunnation.com/thread...22-regulator-adjustment.1289858/#post-1492344

Now I'm ready to collect some tunes! (tuning numbers)

PLEASE POST YOUR FAVORITE TUNES HERE:

18.1gr factory tune out of the box (.22 cal): Power Wheel (Macro) 22 / Micro Wheel: 2.5 / Regulator 85 BAR
This tunes gives me 90 shots at 890 FPS exactly. It holds 1 inch groups at 75 yards, even if your not shooting your best. Super fun tune for plinking with friends.

....still looking for that 25.4gr tune! -Nate

How to Tune a PANTHERA:

* NEVER shoot a Panthera below the regulator pressure.
* NEVER adjust the Regulator above 180 bar.
* Set the Regulator at the lowest possible pressure to achieve the desired velocity.
* Remove AMMO before adjusting Regulator.

Turning the Reg UP:
* You must have more air in the tank than the desired reg pressure, before you start.
With air in the gun, gently turn the allen screw inside the front top corner of the trigger guard no more than 1/4 turn counter clockwise to increase Reg pressure, check the dial, Repeat until the needle reads the desired pressure.

Turning the Reg DOWN:
* Make sure gun is EMPTY of AMMO before you start.
With air in the gun, turn the reg adjustment allen screw clockwise no more than 1/4 turn to decrease reg pressure.
Shoot the gun with no ammo a few times untill the reg pressure stops dropping. That is your new reg pressure. Repeat if nessecary.

NEVER ADJUST the POWER WHEEL when GUN IS COCKED!!!

There’s been more and more coyotes around my neighborhood they’ve been snatching little dogs in backyards. I have several pups as well and I want to do something about it. I’ve never shot at an animal this big before and hope you guys can give some pointers.

1. Would a .22 suffice or is a .25 required？
2. What fpe is ideal?
3. Are Jsb Diabolos sufficient?
4. What’s the best shot placement?
5. Any tips on luring them out?
6. What’s the best time to watch out for them?

In excellent condition, like new.
