Good move by hastan , most folks like regulators except for maybe hog and larger hunting airguns just don't need MASSIVE power.
Now I have NOT owned a hatsan but it seems many like them and esp. folks who tinker, but, ( and I do know you hear more from folks with problems that people who's rigs work great from day one and for the nest 10 years ) I have seen a fair number of people post - with pics & such also - about metal shavings esp. having to do with the threads on the tube and perhaps other? THAT either needs to be fixed, or, has been fixed ? Love to see some current buyers check & review for such issues. That aside I certainly was tempted by their pump action model at $289 when it was on sale.
Just an old fact, The "A-Team" ( Hans & Ray) regs for the Careers were naturally inationally made for the .177 Target shooters crowd where ES is MUCH more important than power- being able to shoot a full match w/oit refill was nice also but applied only to the long gun. As all the tubes were the same it made sense to sell them for all cal. , reckon just a higher reg set point.
In .25 cal with the long gun it produced 50fpe , sorry I don't recall the set point. 50 is plenty for my anything considering a 3 year old child with a half a crayon can kill, it's just placement. And a reg does help shot placement, esp for the "common" shooter who doesn't always shoot true sub MOA at 100 yards everytime, in the dark, riding a horse over the mountain in a blizzard.
And the NON-vented reg was a pain in the bum. It had a very complicated "bleeding" cycle needed, #1 if you ever shot below reg set point ( if this happen during a match you were likely done for the day) , or #2 enough time had gone by esp. in storage ( pressure equalized then ??? ). And perhaps they moved in the tube if pressure dropped, (seems I recall that ?). OUTSTANDING accuracy! If I could have gotten even 2 shots within say 20fps it would have made long distance much more fun but for hunting large game one shot ( with back up's) worked just fine.
IF the factory has cleaned up the little ( large?) QC problems adding a reg WILL boost sales.
And depending on what crosman may ( or may not ) have reged and shooting 800fps - .177 ? .58 ? Then a QC war could start!!!!! YA buddy a quality control war, that's something we could all benefit from eh?
