I have a Hatsan AirTact in .177 and Edge in .25. I purchased two Vortex Type 3 Pistons to install in them. My understanding at the time was it was a direct conversion. At this point I noticed that there is a "Vortex gas piston spring guide" also available for purchase. So now I am a bit confused.
Does anyone know if the Vortex gas piston is a direct replacement for the spring models? Is there a simple modification I can do? Or, do I need to purchase the "Vortex gas piston guide" too?
Thanks! George.

This guy may know and answer you here.
Heres a bit from his post on ot grom another forum.
I also have houhht you just removed the dpring guide and slip in the ram, but?!!,. On the end of the ram thetes a centering thing .
I do see some have it on the ram and some dont. Maybe thats what they mean?

A link to this "Vortex gas piston spring guide" would help so we could see exactly what it is. Might well be something new that's not on the older guns
which all of mine except the AirTacts are.
The picture Deeco posted is of the endcap and ram setup for rifles with the Quattro triggers, since those triggers slide up inside the receiver and not
under it. The forks on the endcap and the ram gives the trigger pack room to slide up inside and helps hold it.
On the Edge, the endcap has an extruded knob on the inside end that the gas ram, which has a matching indent, centers on. The inside of the piston has
a drilled hole for for the gas ram shaft to center it inside the piston.
On the AirTact, the trigger assembly also acts as the endcap and the spring rides inside it. Like the Edge, the AirTact piston also has that
centering hole drilled in it for the gas ram shaft. The ram is just a drop in upgrade and YES, you will need a spring compressor to reassemble it. There's about
1/4 inch that needs to be pressed back inside the receiver to install the endcap pin and you're not going to be able to do that by hand...lol. Pictures below of
what I just described.
As far as the "guy" who wrote that thread on Airgun Warriors, I'm that guy...lol. Maybe I should see about changing my
name over there and adding the -52 part since it's the name I use here and on Airgun Nation.

Sorry i know it's you , but somehow i i get confused on your suffix here and go with the guy.. duaaa...

I went over there, got in my profile and changed it, so I'm now SteveP-52 on all 3 forums...lol.

Well maybe be that will help my poor fuzzy brain out..

Ok, Thanks guys. Sounds like a drop in upgrade to me again! George.

Thanks! I am assuming that is if you need to do a full conversion?
Nice Avitar. I have a 1975 Ascona. I have owned a GT a long time ago and a few Manta's. Only have the Ascona now. It is the last year Opel was imported to the US and first year of fuel injection.

I have that image in PDF format if anyone wants a link to it.

Used a different browser and saw what Jeff posted. You'll need to make that centering block if you want to reverse the Vortex ram and
have the body of it inside the piston since there's nothing on the Edge rear cap or AirTact trigger assembly to center the gas ram shaft.
Also something you'll need if you want to use a Crosman Nitro piston instead of the Hatsan version.
I've never converted one to use the Crosman Nitro piston but if you search the forum, many have and the info is here to go with Jeff's
diagram.
If you're putting that Vortex ram in either the Edge or AirTact the way Hatsan does with the piston body at the rear, it's just a drop in
conversion with nothing but the gas ram needed.

Thanks! Yes I have two Hatsan Type 3 rams here. Just waiting for some time to install them. I really wanted to crono them first though so it may wait till I get one. Thanks for the information.

Some people think the reverse installation gives a better kick since the weight of the Gas Ram body is in the piston itself.
Never actually tested that myself so can't say.
Now what I am going to do is get a Gas Ram and do the reverse install on a WAY older 125 Model.
-
I found a Mod 95 with the Gas Ram in it stuck back in the corner so I'll 'borrow' the Ram for the Winchester 125 for now.
Also found 22.23mm Delron rod in the basement work shop. Also have several Piston seals to choose from. And Krytox lube.

I'll start a new thread to cover the progress.
