Chuck ,you are in the sweet zone for the caliber stroke ratio combo of the Hw80/R1. 14 to 15. Lbs. The kit is doing exactly what it’s designed for. Enjoy it as sighted at 30 yards it will be good to 60 with little to no holdover. The extra 4 ft lbs makes no difference down range Accuracy and they start to suffer in shot cycle after that. This is from someone who has built several 30 plus ft lb guns.

I made a few of these back in early 2000s. Finally gave them away when I quit shooting field target. I used big Fender washers around hole on mine.

Hey there,

I've been wanting to design a red dot mount for the GK1, and regarding that I am in need of some measurements.
Does anyone know these two measurements? It needs to be precise so that the mounting plate doesn't have any play in it.

I thnk it is especially wonderful in this or any hobby . WE all have met and talked to so many people . IT doesn't mater where they live near or far , what would the chances be to meet anybody on this Forum under your normal daily habits ? I am lucky to be able to travel to the Air Gun Shows and i meet a lot of AGN members . I do wear an AGN T shirt with beerthief on it , otherwise WE would just walk by looking at the tables we would never know who was there .
EDIT: if you see me stop and say Hello

actually I don't even know how I found AGN forum but very glad I did, I've had wonderful conversations with some of you, probably wouldn't have met my friend Felix right here in Rogue River.. and definitely wouldn't have gotten to see a lot of guns that I'll never be able to buy..
yes technology is hard, I make the most of what I know..
I does upset me when people complain about the rules and want to change the forum,it like they are not thankful that all this exists.

Heard about the issues Stoeger seems to have with their whole XM1 series as a whole, was hoping this would've been solved by the time I was actually looking to purchase a PCP, especially for the higher end versions like the bullshark.

I’d be curious as to these stories. Not a challenge .. I want to hear what they are ?

Did Tuxing have any solution other than return? My buddy has a similar issue on his 042, but at 3200psi on a dedicated circuit... I've had good luck with my 012 so far, luck of the draw I reckon.

Click to expand...

I have bought 3 Tuxings, TXED011,TXED012 they both run great with a little upgrading, but my luck with the TXEDT031 was knocking a month in use. a bad connecting rod by their words,they had me make a video and the remove the cover to the crank case to verify,they said they would send parts while under warranty. They refused to take it back. I had Asurion they dropped me and told me that someone made a mistake in selling it to me. so, i took it to AMAZON and they did nothing. So, when buying a Tuxing compressor, keep it simple, the tuxing 11 is 4 years old and 1 rebuild kit still going strong as with the 12.

Meaning as in pellet brand and weight?

Meaning pellets, HS, and reg setting. It sounds like you have a laser the way it is. I would definitely leave it alone and just enjoy shooting it!

do you also have a GK1?…

@markhooper I do.

Thanks for the hot tip. I ordered a dozen. Crow.

With your abilities, you could weld the silhouettes to bolts that would screw into that spring. The stop may screw into it. If so that would give you the thread and pitch of the bolt to use..

I would pay Derrick wall to reseal whole gun and your back in business....no need to get negative replies from another member

now i did find my flat top kit after searching for too damn long 10 years ago put it in a place you will remember i said sure that worked
but it can take some picture and measurement if you like but without the valve and a heavy hammer spring it would not be complete and yes they have gotten expensive

elwoodblues said:

Have you got a link for that on

Click to expand...

There are a few things on that page. The only issue I had was the provided design is for 22cal. I tinkerered with the model a little to get it to work with .177 premiers.

Color me confused I’ve been trying to find a resource to buy the n50 and 30 yard and 40 yard paper targets and I keep failing. Any suggestions ?

Click to expand...

I print out the N50's from the national50 website - print them on 8.5x11 and tape them together - yields the same size target.

Hopefully they will be here in the USA soon.

Great write up, thank you very much. Knowing that close tolerances doen't yield a better result is really valuable.

I was talking PB land, I don't know how much translates to air rifle land, but shouldn't be too much different. I actually had a machinist freind cut me an adapter for my big 30 cal suppressor mount so I could put it on the uragan barrel. I put it on my uragan compact with the shroud removed, it was as quiet or so close as it was irrelavent with the 30 cal endcap on, the alignment was good so I put the 22 end cap on and it was probably more quiet than the uragan with the baffled shroud, and as quiet with the baffled shroud + adding on the uragan suppressor on the end. Lower muzzle pressures in general with air rifles, and smaller volume of gas except in rare cases. The most quiet suppressed PB I ever didn't hear, was a friends 1920's winchester pump .22 short only gallery gun he inherited from his grandmother a few years after his grandfather died. Without the suppressor on the end of the barrel, it was more quiet than a standard 16" 22 rifle with a really good suppressor. Put on the 1920's tiny little suppressor, shorter than my little finger, and smaller in diameter than my little finger, with I think 5, maybe 6, small pressed spring steel baffles in it you could put your ear 2 feet from the muzzle and hear a very quite push of air that you could do way louder with your mouth blowing for 1/2 a second. There are always exceptions to the rule, the muzzle pressure on that 18" 22 short rifle was likely significantly less than a 10 meter olympic air rifle.

As others mentioned, the wheeler fat wrench is a good idea to have. I also went through sort of a binge buying of pits this past winter.
Top left is Lowe’s Kobalt, top right doesn’t have a brand name I think from Amazon, bottom left is Harbor Freight and bottom right is Klein Tools I bought at Lowe’s. The top and bottom right are nice because they include the driver handle. The Klein set is a small hex bit size so it’s good it has its own handle.
The Lowe’s Kobalt set is pretty nice because it has a ton of different bits. The Klein set is nice because the bits are small and airguns often have small fasteners. The Lowe’s Kobalt set is especially nice because it has MM & SAE hex (allen) bits so it’s really not necessary to also have allen wrenches.

@gendPC Who makes that rifle?

Click to expand...

its the Pinty bullpup (P-pup), its been confirmed it is not identical to the spa guns.

The one I have is fairly original ie. being purchased as soon as they were available, ill have to look up the serial number, It came with the + neutral - barrels and all performed the same way. All had the same borescope picture, I have tried about every possible combination and pellets with the same results it will throw flyers, I shoot with red panda and Pantera guys and their guns do not do this. RP having full cut rifling and the FX polygon all shoot better. However the push test on each one the pellets conact the barrel edges completely though and choke on the end. Skout not so much...

I was referring to his FT background. I thought it was funny when he mentioned the Hatsan break barrel.

Lots of us Bulgarian guys are using the alpha precision barrels, especially for FX. Haven't heard one negative.
All guys I know use polygonal, all calibre. I've a 650 mm barrel shooting baby slugs .177 better than I ever dreamt.
The delivery from Spain is painless, my last order was 110 euro per barrel plus 8 or so euro shipping.
Definitely a risk I'm pleased I took.

I checked Balistas and they are saying, "long-term unavailable," whatever that means.

Tuning the M4.35 cal.

just installed .35 caliber on a new FX4.

M4 is now shooting Fx slugs 68 grain at 850 FPS.

The Tune is Micro 4.7 and Makro 14 .Valve 4. Reg is at 110 bar.

Please advise.

Thanks.

Imagine this...
I found these in bottom of my YH crate...



Completely forgot when was that somewhere back in time I bought these.
Today started a workparty, definitely I need to organize my parts inventory ... I have some many things collected just hard to remember.
These happens when I buy "just in case".

Sweet keep knocking them down..

Tape shim on the folder hinge is simple genius. I'm taping my aea tomorrow and double checking that the fx has no slop. Thank you for this great idea

Also a piece can go on the buffer tube. I forgot to mention that. Yea clear gorilla is perfect it is 0.1mm which and tough as nails it lasts. Glad it helped someone.
