the answer is yes...and no
The older models can't hit anything 50 feet in front of them.
I had 2 back in 2000, could put a 3 shot group in to PB ,mask @ 120',
there were a lot of tings you could do, the nozzle is chocked down to keep it 1j, booring it out gains a lot of power,m add adjustabul hop up.. if you have one never use the shells the cause horbily accurcy issues
the S9 is the UHC copy of a (drawing a blanke here), A lot of things have been done to it, even a spring so large you have to cock it with your foot by standing on it (used for hunting)
10 years ago it was the ONLY choice for a budget bolt gun, now it is just not worth the money, too many good l96/vsr10 cones on the market for the same price..
it is a relic, and old dezine that was ok in its day, but wasn't able to move forward... compare that to the aps2 witch has set the bar by witch all others are judged
"snipers" are eliests.. if they have a $$ gun all the outhers must be crap, this is one reasoning(far from the only) the S9 got such a bad rap
I rember with the bar 10 came out... all the "real snipers" said it was a cheap peice of junk for 2 years... then the after market parts caught up and the brilance of its hop up system shone threw.
