Hatsan Jet I/II Discussion

[hfenn]

Thanks for sharing this!

I had some free time today, so thought I'd give the Jets a little attention...  Guess what, the trigger on the Jet is adjustable!  Yep, you have to remove the grip to access it, but it's there, a small grub screw right behind the trigger!  I gave it a few turns in to take up the slack, and yep, much nicer now!

I also took a couple pics of the trigger assembly.  All the improtant parts are steel, so they will be getting polished in the near future.  There will also be a couple springs replaced as well!  The first stage trigger spring is not bad as all, but the one of the back of the assembly seems pretty heart and wound pretty tight!  I'm thinking a lighter spring there will make a huge difference!  More to come on that!


I also discovered there are two spacers already behind the hammer spring!  Since I wanted to detune the .22 a bit, I pulled one from it and added it to the .25.  I've not had a chance to run them over the Chrony yet, but hope to this weekend.

In any event, thought I'd share these little findings with y'all.  Also added a pic of both Jets, the .25 has the slig and is zeroed with the iron sights, the .22 is equipped with a small red dot.  Both have Sortie Magazines for more shots between reloads!  Have fun!

Thanks for the information !  I can ony shoot mine(.22) indoors at 5 or 10 meters, so I will need to de-tune it as much as possible.  Have you located a parts list or EVP ?  Thanks.

I requested an EVP from Hatsan USA and they sent it about an hour after the request.

I need a little help. I just bought my first PCP, a Jet 1 with a hand pump and after filling it to 200bar I cannot get the pump to release from the foster connection. When I bleed the pump it empties all the pressure in the gun too. It will finally release when the pressure in the gun is less than 100bar

if its dumping the entire gun the problem is the foster, i had to replace mine within a week of owning the gun .. its m10-1.0 thread pretty standard

I had this issue with mine while trying to fill from my 90ci ait tank.  Be sure when you release the pressure using the knob on your hand pump that you do it as quickly as possible!  Releasing the air slowly will allow the pressure to bleed from the gun because the valve in the foster fitting isn't closing fast enough.  It may take filling the gun and then quickly releasing pressure a couple time to get the valve to seal correctly.  After doing that with mine, I've not had any further problems.  I used a compressor and filled it to a full 250 BAR, I know that will be tougher doing it multiple times with a hand pump, but hopefully it will work for you.

It looks like PA has the Jet  dual air cylinders in stock (Black anyway) for $119.99, $10 less than on the Hatsan website.  The GTA code takes another $12 off that price dropping it to $107.99 before tax and shipping.  They also have the single air cylinders for $99.99, but that's $20 more than Hatsan told me they would cost when I e-mailed them a couple months ago, and they are currently for pre-order only.  Hatsan has the single listed for $119.99 (not sure why when they told me $79.99) and the dual for $129.99, even though neither is currently available direct.

My plan is to convert the .25 to a dual cylinder and then use the single cylinder as a spare for the .22. 

I really don't understand the pricing since the dual cylinder has 2 cylinders and the block and the single is just a cylinder, the $10 difference doesn't really make the single cylinder much of a bargain!

[Rat Sniper (AKA: PaulT58)]

The Jet dual cylinder accessory arrived today and I installed it on my .25 Jet, converting it from a Jet 1 to a Jet 2.  It's a very straight forward, easy transition, and I'm not real sure why they have the warning to not do it if the cylinders are under pressure. 

I did remove the single cylinder from the gun since it is hot swappable, and then removed the block which contains the valve, male foster fill and the screw on adapter for the single cylinder.  The dual cylinder accessory comes with the block that also contains the valve, so it was as simple as removing the bottom two 3mm screws and then loosening the two 2.mm grub screws that are under them.  Then you just slide out the old block and slide in the new one, tighten the grub screws and reinsert and tighted the other 2 screws.

Since the valve will hold pressure when the cylinder if filled when it's ni the gun, I don't know why it wouldn't when it's outside the gun.  The old valve/block assemblt could probably be used to fill the spare cylinger when it's not attached to the gun. Here are a couple pictures of both Jets, the .25 as a Jet 2 and the .22 as a Jet 1 with the spare cylinder.  Also a picture of the block/valve assembly from the Jet 1 without the cylinder attached.

Has anyone done any shooting the jet1 just as a pistol? I thought about getting one but if it's too much to shoot 1 or 2 hand I don't want to bother.

The single cylinder model is not bad one handed, the Jet 2 with the dual cylinders is a bit heavy for one handed shooting.  Also, the two picatinny rails on both side will come off with a singlt 3mm screw which makes it much slimmer as a pistol.  Without adding a moderator, it's very easy to handle, but not exactly back yard friendly.  If th weather holds, I'll try to get some pictures this afternoon.

Thanks I don't think I would put a mod on it that's a lot of leverage hanging out there.

Here are some pictures of the Jet 1 with the side picatinny rails removed.  You can get an idea of the size with and without a moderator:

Thank you Paul I really appreciate you taking the time to post that. Kinda reminds me of say desert eagle 50 or a smith and Weston 500 as far as size goes. Make me want one more and I like how that sight looks.

See why I want to power up a .25 and keep it a pistol

I probably missed that I started skimming a few pages ago. How ever I think if you wanted a nice truck gun or tractor gun etc and wanted to take down say a hog or such then sure.

It is very sleek, and I do like it. If I had an unlimited budget I would have all of these little PCP pistols/carbines.

Do you really think one of these would take a hog?

[Rat Sniper (AKA: PaulT58)]

I don’t think they have the power needed to take anything larger than a squirrel!  Hogs have pretty thick hides and even thicker skulls!

I think they would also be suitable for rabbits/hares, very thin skin and fragile bodies. Squirrels are downright tough critters, but I find they go down pretty hard at 19 FPE. At 12-ish FPE I had a lot more runners and having to dispatch them by hand. With the same 12 FPE gun I put down a hare with no struggle at 35 feet. Personally I would not try a hog with any PCP pistol, except for maybe something like the Evanix Rex "pistol".

Lol... Yes. Do I think YOU can no.

Maybe as an execution tool at point blank range it would work. I just can't see 16 FPE being enough at any distance
