CaptC Posted February 18, 2020 Report Share Posted February 18, 2020 Just acquired an older Hatsan (yes I know, had one before) from a deceased estate. The gun has been standing for a long time and the oily crudd in the workings took a bit of cleaning but half a can of WD 40 seems to have shifted 99%. My problem is with the barrel - it will not release from the breech. There is movement around the gas ring and at the breech but the barrel will not pull out? Help please!

Smokersmith Posted February 18, 2020 Report Share Posted February 18, 2020 I've had the odd sticking issue over the years .. What helped me was (with the forend off), release the bolt and let it slam forwards a few times. I think it's the sharpness of the slam that loosens things.

TIGHTCHOKE Posted February 18, 2020 Report Share Posted February 18, 2020 The barrel gas housing will have become a little too intimate with the gas parts. It will probably take two of you to seperate them after a good soaking of something, whether it be light oil or petrol which is a great penetrator. Good luck Mate Quote Link to comment Share on other sites More sharing options...
ratass Posted February 18, 2020 Report Share Posted February 18, 2020 itll take a good clean after but try soaking it in coke cola. JB Quote Link to comment Share on other sites More sharing options...

spurs 14 Posted February 18, 2020 Report Share Posted February 18, 2020 Contact or brake cleaner from your auto parts store ,liberal spray, wriggle ,spray , wriggle don’t worry about leaving to soak it evaporates but will dissolve all the crud , you may need the mallet once charging handle is out there’s nothing physicals holding it , good luck Quote Link to comment Share on other sites More sharing options...
CaptC Posted February 18, 2020 Author Report Share Posted February 18, 2020 Excellent responses - thank you! I have liberally soaked it in WD40 with little sign of budging. I will give another seeing to before bed and if nothing shifts tomorrow morning it's brake cleaner time! I have tried releasing the bolt against the chamber - zilch! Strangely, all the oily crud has gone but I fear that there is more unseen behind the receiver. Quote Link to comment Share on other sites More sharing options...

Rob85 Posted February 18, 2020 Report Share Posted February 18, 2020 Any way you could get something attatched to the barrel and use a slide hammer to shock it out with a few pulls? I've been toying with the idea of getting a hatsan to see how I get on with a semi auto myself Quote Link to comment Share on other sites More sharing options...

Keep your eye on Gunwatch because it will be for sale when fixed! If you had a fired shell, knock the primer out and push a thin piece of threaded rod down the barrel and through the primer hole of the chambered empty shell, secure it with a nut and you might get lucky. I'll grant it is a bit of an expense and faff to do but might just work. Another thing I would try is to put the barrel and receiver into boiling water to see if some expansion and contraction would help. Would love to take it off your hands but reckon the distance would put up a barrier getting it to northern ireland!

Would love to take it off your hands but reckon the distance would put up a barrier getting it to northern ireland! Two very good ideas - thank you. I thought of heating the receiver gently with a blow lamp but knowing my handy work something would go wrong. Will try boiling water poured into the breech. Yes, N Ireland is a long way away! Again thank you. 2 minutes ago, snow white said: Warm breech block with heat gun or hair dryer or boiling water anything just to get it just to swell a bit Tomorrows project! Cannot do any harm!

impala59 Posted February 19, 2020 Report Share Posted February 19, 2020 I had a similar problem with a semi auto that I purchased a while back that had been put away wet. First I used a penetrating oil on the mag tube and also the barrel to receiver join and left it standing vertical for a week adding more oil as needed. I still had a stuck barrel but felt that the oil had certainly penetrated sufficiently. Using a nylon drift on the barrel ring/gas vent, a couple of sharp taps got a millimetre or two of movement. More oil could now get in and the next day one tap was all that was needed to free the barrel. There was serious rusting, but thankfully only surface (although a bit of pitting) and where the barrel extension contacted the alloy receiver there was some serious crud and the steel had stuck to the alloy rather like alloy wheels on steel hubs. It needed a serious clean but was fully functional afterwards with the addition of a new gas ring. Just take your time and all will be well good luck Quote Link to comment Share on other sites More sharing options...

Just take your time and all will be well good luck Good morning, Thank you for your advice - My gun is exactly as you describe - stuck solid in and around the piston and possibly around the receiver joint. Half a tin of WD40 has worked its way through and a lot of crud is coming out. Some "gentle" taps with a rubber mallet got a millimeter of movement so yet more WD. I tend to rush at things a bit as patience is lacking but slowly slowly catchee monkey! 5 minutes ago, TIGHTCHOKE said: Dissimilar Metal Corrosion! Don't think so, the high quality best Turkish tin has no rust at all. I think the gun was, as impala59 correctly says, put away uncleaned and wet. I'm off to the shed for the sledge ------- Quote Link to comment Share on other sites More sharing options...

CaptC Posted February 19, 2020 Author Report Share Posted February 19, 2020 Well, the barrel came off with the piston attached. Gentle (?) tapping with a rubber mallet and off it came. The O ring had disintegrated and stuck hard. Took a lot of effort to clean it off. Just sent off for new O rings! Thanks to everyone who contributed - A splendid PW effort! The only downside was the constant nagging from the Memsahib as the oily juices spread along the kitchen floor. Better go and make an effort to clean it up as the dear lady wanted "some fresh air" for some reason? 6 minutes ago, GingerCat said: Quick wipe with an oily rag when putting away does wonders.
