I have an AR-2000 Jet (Tech Force Jet) and if you want power, it isn't a bad rifle to go for. I'd recommend to you the .22 over the .177 simply because at these power levels, the .22 is beginning to strut its stuff over the .177... It has the thumbhole type stock, which I am not really a fan of but I got used to it eventually, that and the fact you can't get the standard stock version (if there is such a beast). It is quite a big unit, no bad weight-wise compared to other powerful rifles, very average in that respect. It takes a handful or strength to cock, not the first few times, but certainly if you paln to shoot all day. It promises some accuracy and seems to deliver. I can't remember which pellets I use in mine, either JSB Exacts, or Exact Kings or is that Exact Heavies.? Whichever,, use heavier pellets for this one, something in the 16 - 18gr range as it has plenty of power. Mine chronys in at the equaivalent of about 26+ ft-lbs, so that is certainly in the no nonsense bracket - serious power stuff... For a Chinese air rifle, this one is not that badly made and things fit together quite nicely and look reasonably well finished for a cheaper rifle... Would I recommend it - certainly... The only thing I can't comment on is its overall reliability over a longer period of time, because I haven't shot mine enough or owned it long enough to get an answer. I've had it for about 10 months now but I have too many air rifles to keep using one or two of them...
Ahh ok,nice to know that they will hang in there. I also had an AR1000, same as the Tech Force 89, which was also a little powerhouse. I like the looks of these rifles but as I said above, I don't really get into thumbhole stock, but I have to admit that the new Diana 470 looks realy nice in the style... The weather's starting to warm up here at last so hopefully I can go for a few strolls and get back into it again. Maybe the 2000 Jet can get some more work in...
I've got one of the Beeman RS2 Sportsmans, also an AR1000 variant and its a great gun. 18 fpe and excellent accuracy. The Jet I am certain has a lot more power potential hidden away inside. I'm going to be adding an aftermarket seal and making a very slight modification which I believe will put it near 30 fpe, without changing ANY other parts. Should be interesting.
