Whether you think it needs it or not.

If you are like me and bought this gun over 5 years ago and have never felt the need to service it, here is your wake up call.

I noticed a very slow leak starting that wasn't really effecting use, but I have never serviced the gun, and I often handpump fill it, so I was curious to take it apart. That's the interesting part of this story, the threads on the air tube really did not want to unthread. I don't know what they used when they assembled it but it became a white sticky powder that had more the properties of loctite than silicone. Luckily I have a big bench vise and strap wrenches and a 2' long steel rod to put through the fill port, because it took all of that to get it off the tube. I am glad that I didn't wait any longer.

It was, in fact, the oring in the fill port that had started to fail that seems to have been the problem. I changed every oring I saw anyway. The only oring I didn't change was a very tiny one on the valve. I don't have anything that small. I didn't know they made orings that small.

The inside of the gun did look good though. It's no wonder this gun loves slugs, the barrel is really good. The rifling and the crown look just about perfect. The best part of all of this is that after I put everything back together and aired up, the zero had not changed. I opened my door to shoot at my 95y spinner, and the first shot missed but was real close, tried again, bingo! It was me, not the gun. I was using 12.5gr NSA slugs. This gun loves them, and it doesn't need a bore scrubbing all the time either.

The plastic on this gun, and how it is made and machined, puts the aluminum receiver on the Flashpup version of this gun, to shame. I could not believe how rough the internals were on the Flashpup, though it was accurate too. I think they did a better job with the Vectis.

Good for another five.
 
Good thoughts. I've got a Vectis that was re-barreled a couple years ago. I've taken it apart a few times to install a Huma regulator and then a few more times to adjust it. I've never had a leak or a failure. but it's a good reminder that if you don't take care of (or send in for service) your gun you could eventually have a catastrophic failure. If you're shooting spinners at 95yds, you must have an excellent barrel. I haven't tried mine past 50 and it was so-so

My barrel is perfect, as far as I can tell, or that matters. It shoots the JSB 10-13gr pellets as accurately and loves 12.5gr NSA slugs and has done .75" groups at 75y. People are constantly ragging on Hatsan, but to me, they have been outstanding shooters. I tune out the negativity at this point as I believe people have to pick on the low end so that they can justify having to buy a $3k gun that basically shoots as well. Whatever.

I've got a Hatsan Invader semi auto 25 cal I've had for 3 years and it's been trouble free with no leaks so far. I got a great barrel as well as at 30 yards i get dime size groups with JSB 25.39 pellets so it's been one of my most reliable pcp rifles i own! Now, if it only wasn't so heavy.....

I see plenty of QC complaints about Hatsan, every one I've shot has been great. My normal recommendation is factory refurbished for people. Double the QC passes, and already had issue(s) fixed.

You know I still wonder if i actually got a decent barrel on my last barrel change or not. At 30 yds, about the best i can do is about an inch. I've tried several pellets. Seems like it shoots Polymags the best and is so-so with H&N Field Target Trophy pellets. I'd hate to send it back but I'm just not totally happy with it. Got a regulator in it set at 145bar. Maybe I just need to play with the hammer spring more. Dunno. Any one got thoughts?
 
If you're still talking about the Vectis, I would take the barrel off, bronze brush it with the lead removal solvent of your choice, then polish it with JB Bore brite. Try shooting it after that, and if you can't cover your groups with a dime at 30y I would order another barrel, they are fairly inexpensive. Some barrels are definately better than others. I have been pretty lucky myself, with Hatsan barrels, but I do the above procedure first too. Also, I wouldn't push wild speeds either, unless you are shooting slugs, which tend to like speed.

Yes, talking about my Vectis. I'll try that, thanks. So is this something you do with all your guns or just the ones not shooting so good?

When I first buy a gun, I usually do this first. I just so happen to usually not have a problem with accuracy either. I think the industry is doing a pretty good job with barrels, for the most part. Some of the worst finished barrels I have seen, were on SPA guns, and they still shot good.

I forgot to mention that I did cut off the muzzle brake and direct thread a Tanto suppressor on the end. The brake on the Vectis is worthless and actually heavier than the DonnyFL Tanto that I use.

Funny you say that, that is exactly what I do and for the same reason. It has worked for me, and mine have looked factory new, plus they are incredibly cheap to buy this way. And here's the best part, because I bought directly from Hatsan, when they determined the first batch of magazines were defective, I didn't even have to contact them, they just automatically sent me new perfectly working magazines. Pretty good service to me.

Yeah, I've been wanting to cut the original muzzle brake off and put a moderator on it. I think my biggest issue is a bandsaw or something that would cut straight and neat. Plus for me time is a big factor on anything.

Funny you say that because that's where I got mine; Hatsan refurbished. Sent back for one barrel; maybe two? Dunno. When weather warms up I'll clean it like you said and go from there. And It's got quite a ping so I'm going to stick a baby bottle brush in the tube also.

If you have the time to shoot it, you have the time to make it better. You don't have to be too concerned with your cut being perfect. You can use a file to flatten the cut after, or even sandpaper, though with a file it is far easier to do it flat. I was amazed how loud that brake is, and how quiet the gun was with a Tanto. I have actually had the opportunity for second shots on Starlings in a tree top, that's how quiet it shoots now.

I have the .177 no regulator and I only fill to 2500psi for one magazine (14shots) and use a Tanto and I do not even have a hint of a ping. Before you stick a brush in there, stick a Tanto on the barrel.

Okay, one final question....is the barrel already threaded on the end or will I have to cut threads on it? I've never actually taken it out, but I think it just screws into the brake, which leads me to believe the barrel is threaded. And since it screws in, doesn't it have to be 'set' in a certain position to actually shoot good? (like a certain mark be 'up' etc?) Thanks. Sorry for so many questions.

The barrel is already threaded for 1/2"x20.

Here is a video to watch. The guy is a little long winded but he does show how to remove and cut things. I did a lot of measuring to make sure the face of the shroud was going to rest against the screwed on moderator, before I cut. Just be careful and you'll be alright. You will need the long reach extension with a 14mm(?), he says, and shows it on the video.
Good luck!

If any moisture would have gotten in, it would have showed up in the fill nipple, the tube, the valve, valve spring, everything, not just one section of threads, and that section wasn't the leak. The leak was the bad oring on the fill nipple. The inside of the gun looked very good, as I put a drop of silicon on the fill nipple every so often. I think it must have been something present at original assembly, regardless, I put the grease on it that AAA recommends, so I don't see it being a problem again.
