Two questions that we are frequently asked are can I make my airgun more powerful and is it viable to up-rate the weapon to firearms status?
All responsible manufacturers have for some time been incorporating anti-tamper devices in their products to ensure that the guns cannot be illegally increased in power. The trade can now easily ascertain if attempts have been made to alter the kinetic energy output and if found then the warranty is deemed as cancelled.
Our legal limit in the U.K. where an air rifle can be purchased without a licence is 12ft lbs kinetic energy and 6ft lbs on a pistol. Elsewhere in the world it can be a lot lower so customers in the U.K. would do well to avoid purchasing “grey imports”.
