For up to 40% more compressed poundage than conventional mainsprings.
Fitting this spring may take the rifle over the legal limit.
They may require cutting to fit, (guides on YouTube).
We only recommend you use a Gunsmith.
Recommended to use Bisley moly grease.
WARNING:
Replacing a mainspring is not a straight forward task and can cause serious injury to yourself or others.
We recommend you use the services of a professional gunsmith to change the mainspring.
The new replacement spring can appear longer than the old one that you are replacing,
which has likely become compressed over time.
After your new spring is installed, you will need to use an accurate chronograph,
to check it has not taken your rifle over the none FAC legal limit of 12ft/lbs.
Also available ~ Titan Airgun Mainsprings.
OX Mainspring® Shooting Stronger for Longer Since 1981.
