WHAT IS THE DIFFERENCE BETWEEN FPS AND JOULES?
FPS measures how fast the BB is travelling. Joules measure the energy carried by that BB.
Because BB weight changes the relationship between speed and energy, FPS on its own does not tell the whole story.
This is why proper chronograph testing should take BB weight and joule output into account.
WHAT ARE THE UK ENERGY LIMITS FOR AIRSOFT?
For the statutory airsoft exemption, the relevant upper kinetic-energy thresholds are 1.3 joules for weapons capable of automatic fire and 2.5 joules for other airsoft weapons.
These are legal classification thresholds, not recommended game limits.
Airsoft sites normally set their own considerably lower limits, and you must always comply with the rules of the site where you are playing.
DOES HIGHER FPS AUTOMATICALLY MEAN BETTER RANGE?
No.
Hop-up performance, air seal, barrel consistency, BB quality, BB weight and overall setup can be just as important.
A well-set-up airsoft gun at sensible power can often perform better in real gameplay than a poorly tuned gun producing a higher FPS figure.
SHOULD I USE A 7.4V OR 11.1V LIPO?
Use the battery type and voltage appropriate for your specific AEG.
An 11.1V LiPo can increase motor speed and trigger response, but it also puts greater stress on the electrical and mechanical system.
It is not automatically the best battery for every gun. If the manufacturer recommends 7.4V, do not assume an 11.1V battery is suitable.
HOW SHOULD I CHARGE AND STORE A LIPO BATTERY?
Use a suitable LiPo balance charger and follow the battery and charger manufacturer's instructions.
Do not leave LiPo batteries charging unattended.
Inspect batteries regularly and do not use packs that are swollen, punctured or damaged.
For longer-term storage, use an appropriate storage-charge function rather than leaving the battery fully charged or completely discharged.
WHY DOES MY GAS GUN PERFORM WORSE IN COLD WEATHER?
Gas pressure and efficiency are temperature dependent.
As temperatures fall, many gas-powered airsoft guns become less efficient and may cycle more slowly, lose consistency or struggle to empty a magazine.
Gas choice, magazine temperature, gun design and maintenance all affect cold-weather performance.
HOW SHOULD I MAINTAIN MY AIRSOFT GUN?
Keep the barrel clean, use good-quality ammunition and inspect the gun regularly for loose or damaged parts.
Do not flood the hop rubber or inner barrel with lubricant, as this can seriously reduce hop consistency.
Gas seals and moving components should only be lubricated with suitable products and in accordance with the manufacturer's instructions.
CAN JD UPGRADE OR REPAIR MY AIRSOFT GUN?
JD can help with a wide range of technical work, maintenance and upgrades on a case-by-case basis.
Rather than treating every gun the same, we prefer to understand what you want the gun to do, how you play and what your budget is before recommending parts or work.
