Are all the Hatsan Blitz problems fixable?

[Dstrac]

I would really like some info from you on the Blitz. I went to take it apart because of the intermittent jams and I took all of the screws off of the faceplate except for the one I stripped. Would you happen to know what size screw that is? Any help is appreciated.

I sell replacement sets on ebay for cheap that are hex head not Phillips. It's an m3 diameter. We're you able to get it out? Look up hatsan blitz cover screws on ebay. For any other part go to hatsanairgunsusa.com they stock everything you need and have a diagram of the entire rifle.

I got it out but now the gun is effed because I proceeded to take it apart and was checking the semi and full auto. Was going well until I squeezed the trigger and there was no tension just moving metal. I picked up the gun and saw this. Where does it go?

 

[Dstrac]

Look up blitz exploded view on Google. There aren't many pins like that. Looks like maybe the trigger assembly? What about the hole i circled? Not positive

 

[Kneepit]

It was actually the hole behind that one. Now it shoots but isn’t cycling. Hoping it’s air pressure so I’m filling it now. Send me a link to your eBay store I’ll get the set for sure…. These things suck

Awesome, yea there were only a few pins on the diagram. I actually just ordered a new full auto gear and brass bushing from hatsan for mine. They are under the other cover with 5 screws. The brass wears out and needs to be replaced.

There are cover plates on both sides. 5 screws on one side 2 on the other. Eventually the heads will strip and you won't be able to get the covers off to clean and oil your Blitz. That doesn't make a difference.

If you haven't already I would definitely open the cover on the other side too and inspect, the auto gear. The sprocket in the middle that drives the pellet pusher rod. Clean and lightly oil. Mine had a ton of slop. If that bushing is too loose it will bind up

Now I’m bummed. It’s not cycling and has something definitely to do with the bolt not having enough pressure to reset, tank is full

 

[Kneepit]

I opened both sides and it was greasy , thick gunk so I cleaned it. I got it to fire a single shot in either semi or full auto but after each shot I have to reset the bolt. It’s like there isn’t enough pressure to reset.

 

[Dstrac]

I would re open the side with 5 screws and make sure nothing is catching or misaligned. Did you remove the spring at the muzzle inside the barrel shroud? That can effect the tension.

 

[Kneepit]

I went ahead and contacted Hatsan and they are having me send it in. I’ll let you know what comes of it. Thanks for all of your advice and help

Blitz, Barrage and Bullmaster all suffer from the same basic issues.

They need a defined regulated pressure in combination with a matched return spring, especially if moderated. The Blitz and Barrage both benefit from an appropriate sized plenum (Bullmaster has an internal plenum). It is a bit of work but once you get the combination right they are pretty reliable. Downside is there is no one setup, each gun appears to like a different setup. That could just be my impatience and there really is one...

try to shoot it without the moderator attached.
