Hop-Up Bucking

A black hop-up bucking, designed for more powerful replicas (with an M120 spring or stronger), as the material from which it is made is more resistant to wear than silicone.

What is the hop-up system?

Hop-up is a system that spins BBs fired by airsoft guns. It uses the Magnus Effect to flatten the trajectory of a flying bullet and thus make it similar to the trajectory of a real bullet from a firearm.

In practice, it is a properly formed rubber or silicone gasket, which, when touching the speeding ball, gives it a rotational motion. The simplest explanation for the Hop-Up system is that a spin-up BB on one side creates more friction with the air, which can cause it to turn. When the spin takes place in the horizontal axis, the ball will turn upwards, thus balancing the force of gravity.

The force of pressing the Hop-Up bucking against the BB determines how much it will be spun, and thus the lifting force. The heavier the BB is used, the stronger the pressure of the bucking must be (because the heavier BB has greater inertia and falls downwards faster). It also works the other way around – when a light BB is too much spin, it can fly above the line of fire.

A valid defence is required to purchase any Airsoft Replica Firearm. If you don’t have a defence you must add Two Tone to your basket.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

To purchase a realistically coloured Airsoft Replica Firearm (RIF) you must have a valid defence.  The most common of these is UKARA which stands for United Kingdom Airsoft Retailers Association and is essentially a database of registered players.  UKARA requires you must be a site member at any of the registered UK Airsoft sites.  This means you must play 3 games in MORE  than 56 Days. Once you become a member you are added to the database, please note paperwork and validation is required.  There are other types of defence, but UKARA is by far the most popular.  Please note this only applies to the gun, not the kit or accessories.

If you don’t yet have a defence, you can always add two-tone to your order. This simply means you have 51% painted in a bright colour such as green, blue or orange.  You can then purchase any RIF you wish.

If you have any questions regarding what is or isn’t a defence, or just looking for some general airsoft advice, then please drop us a call or contact us here
