I have a Diana 24 that is about 15+ years old. I know for a fact that it is bone stock. It was shooting at 617 fps with JSB Exact Express for 6.65 FPE. Seems odd.

“In Germany, air guns producing a muzzle energy up to 7.5 joule (J) (5.53 ft·lbf) can be owned by persons from the age of 18 years and freely acquired provided they bear the "F-in-pentagon" mark" that indicates a muzzle energy not exceeding 7.5 J (5.5 ft·lbf) kinetic energy”.

If your Diana 24 exceeds 7.5 Joules there are a few possibilities:

(i) If your Diana 24 exhibits the "F-in-pentagon" mark", the spring is not a stock spring but you’re not aware of that or the spring is pre-tensioned somehow
(ii) your Diana does not exhibit the "F-in-pentagon" mark" because it was manufactured before that particular regulation was introduced in Germany.

I believe it may be prior to those rules. I just realized how old the gun is. Probably closer to 25 years.

Most Diana air cylinders are stamped near the end cap with the month and year of manufacture . It is small so get out your magnifier if you need one . Not sure if the laser etched ones are stamped .
