Hatsan Proxima .177

[Mikeflys]

I bought this Proxima I believe the year they were released. Used it a lot for a few years, then it became a safe queen. I purchased a compressor for my PCP's and the springers slipped to the background. I pulled it out of the safe today and was dismayed to find the gas ram has bled completely out. 0 compression when it is cocked. I now have a pellet in the barrel and no means of firing it. Is replacing the ram something that can be done at home. I know with a spring you need a compression tool, which I do not have. She is back in the safe for now, I don't have the funds to send it back to Hatsan to repair right now.

I spring compressor can be made from a simple Harbor Freight bar clamp. If on a tight budget I would probably put a spring in it.

I'm not familiar with the Proxima, so I may be off base here a bit. I've only done a replacement on my 95 Vortex. So generally, if the gasram is totally "empty" you will not need a compressor to remove it. The pins or whatever is retaining the end cap should be easily removed for access, as the ram is de-gassed at this point. However, to install the new or repaired gasram, you will need something (spring compressor, access to a hydraulic press, or even a suitable "bar type" wood working clamp can be made to work) to compress the ram slightly, probably need only 1/2" compression or so at the most. Gas rams don't need much compression to install, as far as actual compression "travel" distance , as compared to a springer that needs several INCHES worth of compression for removal AND installation. IF you are handy, and sufficiently mechanically inclined, you should be able to remove/replace the ram yourself.  Others with more experience will be along to chime in and help you. But having said all this, if you are not confident in doing this type of mechanical work on your airgun, I probably would advise you not to attempt it on your own.

I have read that the Hatsan gas rams do not use nitrogen as do many other makes. They use compressed air. There are those among us who have experience in replacing the seals and refilling them. I presume it would be alot cheaper than sending it to Hatsan for the repairs... providing it's not warranty work.

 Not sure if the Proxima has a ram fill port, some do, you could charge your ram to 120 bar, and at lest fire the pellet out, then see if it holds for a bit while you study up on your next move

X2 on check for a fill port. Some of my hatsan rams had them and some didn't.

I have a refurb hatsan proxima that quickly stopped functioning. Sent it back. Returned a few weeks later with same problem and a crack on the stock.

In short, I got parts if you need them. Just pay shipping or trade me somethin. My last hatsan.

PM member Ronno6.  He rebuilds Hatsan Vortex rams.  I have two he has rebuilt one of which is in my mod 135.
