Controlled velocity

Post by drjones » Wed Nov 26, 2008 1:20 pm

Hi Guys,
I would like to know how to identify an air rifle whether it is a controlled velocity model or not. Particularly the Diana 54.

If it has a 'F' within a pentagon, then the muzzle energy on that rifle is below 7.5 Joules. This is assuming the the main-spring or other internal components have not been changed later on.

It is located almost always on the powerplant.

So does all those without the pentagon mean that they have not been caliberated or exceed 7.5 ?
Will there be anything other than the 'F' ?

noop.. nothing


without the pentagon mean that they are giving full power as much as they are capable of.
Irrespective of the direction of the wind, the smoke from the cigarette will always tend to go to the non-smoker.

Not quite. It depends on the country they are being exported to. German airguns sold in the U.K. via official distributors do not have this symbol. However, the vast majority are sold as sub-12 ft.lbs. airguns.
