You can still get the Turkish one. It’s basically a Hatsan 135 dressed up (or down) to look like the original British one.

The problem with the Patriot and similar 25-30 ft-lbs springers is that they are just too much.

Set aside length, weight, and cocking effort.

The fundamental problem is that they are really really hard to shoot accurately, because so much energy not used by the pellet has to be absorbed during the firing cycle by the gun and shooter, making them exceptionally hold sensitive.

Would you rather shoot half-inch groups at thirty metres with less power, or erratic one and a half inch ones at 28 ft-lbs?

The only practical use I can think of for them is hares at normal springer ranges (though who would shoot hares these days?) or, again at normal ranges, body shots on smaller quarry. Which is pretty niche.

Of course, if you have a spare FAC slot, drop £100 on a British Patriot just for spits and giggles, then you can sell it on at little or no loss when you conclude that it’s a bit silly and pointless.

The best and most useful FAC springers are the .22” HW80 and Diana 48/52, running at 18-20 for the HW and 20-22 for the Diana. But their real-world advantages (esp given the issues around use and possession of FAC items) over 12 ft-lbs isn’t that great. There’s a reason why 99% of FAC guns these days are PCP.
