Common practice for manufacturers to replace rather than repair until they have a batch to go through then someone has to sell them. 

Some have been returned for reasons like " it weighed tio much" some folks just seemingly test drive them & return.

Do check but you should still have a factory warranty so if you get a real lemon the factory likely would just exchange it for a new one.

Never tried a Hatsan refurb but have had RWS34's and Benjamin Marauders from refurb outlets and all were 100% , not even a mark on them except 1 34 that had been stamped "R"> .

GREAT deals on the semi-auto's right now amoung others.



Buy one.

At a recent field target match I was squadded with one of the Hatsan reps, real nice guy. Both him and the other Hatsan guy that were there were shooting random rifles they picked up off the return pile waiting for refurbishing. He had mounted the scope, but just zeroed it on the sight in range that morning. I would have no problem ordering one. You get a rifle with new warranty for the price of a used one from the classifieds here.
 
Have a at44. Mine was perfect but was missing the fill probe and magazines. Had to get a whole new rifle. Long and short of jt was they sent the wrong replacement but I kept out the fill probe and sent it back as defective. There was nothing wrong with it just the wrong caliber. Alot of returns are like that. I love love love my at44. If I do my part it hits nickle size 5 shot groups at 25 yards. Just a cheap 2.5 to 10x40 scope on it.
 
5 in a nickel @ 25yrds. Hmmm. I have 2 spring guns that can put hole in hole at 25yrds. I think your Hatsan hasn't found its favorite pellet.

If Hatsans are 1/2 the gun that Evanix Rainstorms are, then I want a double tank Hercules.

On a serious note. Are you shooting on high magnification, bench bags? I don't shoot on anything past 10x & prefer 6x or 3-4x to make use of 2nd plane focal scope mils extended shooting. I wish Hawke & good tough but cheap air gun scopes offered super fine reticles. I just had to correct testicles to reticles. Glad I caught that. Dam phone. Anyway.

I'm not knocking you, your rifle or skills but a GOOD shooting PCP & pellet combo to me is hole in hole benched at 25 yards. I start at 12 yards in basement. Use stacks of feeler gauges from top of receiver to bottom of scope. I use levels also but usually the gauges are dead on where levels can leave you off 1°-2°. I also Mic my pellet heads. Slug barrel. Work trigger to hopefully 1lb at most but 8oz is preferred.

So Dwight, nice to meet you. I've been around over 12 years now & this can be an addiction. You meet the right guys and used guns are dreams come true. I have an old timer friend. He buys, shoots, tunes & fixes up then sells for less than new when he gets bored. Example. He told me 8 years ago. Jimmy, just buy a Rainstorm II & you'll be happy. Well, I have his .22 with regulator installed. I have NO problem hitting within 2" at 150 yards & that's only 861fps w/ JSB 18.13'S. Under 30 ftlbs.

So again I'm curious about OP question not in used or new but how does Hatsan stack up against Evanix, Rapids, RAW. Not build quality. I know that. I mean accuracy, dependency, ease of changing out all o-rings, porting & self hot ridding or after market parts like HDD or power adjusting other than a reg. Best regs are most likely HUMA.

See Dwight, addictive. To this poster on his 25 yard groups. I've owned over 50 air guns. I'm down to 7. The ONLY ones that I can do what I said, hole in hole are a JIPA tuned El Gamo 300 that I cut recrowned the barrel at 10". John in PA's old TO1 48 both in .177. My JIPA tuned R1 is accurate but I either haven't found the magic pellet or proper hold for that much power. Oh and I'll say this.

I chased "better" when I've owned as good as it gets. 2 spring guns I'd be a Eunuch for to have back are the JIPA tuned .22 RWS54 & Zeus tuned RWS 34 Panther. 125 yards coke can every time & at 50 yards Zeus tuned Panther cloverleaf. The list of PCP'S. I'd want back are my 2 AZ Rapids & all Rainstorms.
 
Just fyi. I have done nothing as far as tuning yet. Rifle is shooting hot but I dont have a Chrono yet so any tuning would be guess work. I shoot from a small plastic picinic table and a sand bag. Lol. Im slowly working my way to a better scope and real bench equipment. The fact that I can hit anything is amazing. I have not found the "magic" pellet yet but my cphp work good enough for my shooting. Is this rifle capable of hole in hole? Most likely with a regulator and some barrel work. Will I ever get to that point? Not in the near future.
 
If you ever want to upgrade to a really nice scope with super accurate turrets so you can dial in elevation for long shots go for a SWFA Super Sniper. I just got one during the 7/4 week sale for $240 delivered. Reg price is $300. If you want a sale price watch them during the typical sale times like 7/4 week. It is a fixed 10x with mil dot reticle and focus 10m to infinity. Reticle is just the right thickness and once you adjust the ocular focus the reticle is super sharp. I got the scope after my Hawke 2.5x10 was stolen in a burglary along with a several low dollar shotguns. Im ok with a fixed 10x as I kept the Hawke on 10 almost all the time and didn't like its reticle as it was too fine for my eyes. It was no where as clear as the SWFA. Never got anything back as the local Sheriffs Office couldn't detect their butts with both hands in their back pockets. FYI the scope is made in Japan, not China. I really like the idea of working up a dope chart of pellet drop then just getting the range and twisting turrets and not using mil dots. But they are still there if you want to use them. You can check all over YT to check out this scope. Im wanting a long range 308 and will top it with a SWAFA variable when finances improve. The variable models are quite a bit more.
