The offset version of the F2 is the first true closed bolt offset HPA conversion kit on the market and, although it took a while to develop, we are pleased to say it is worth the wait. The F2 offset has the same performance and uses the same rear cylinder, poppet valve and other internal components of the standard F2 but the front cylinder has been changed significantly to accommodate the offset nozzle.

The front cylinder has been designed to work with our two piece offset nozzle which comprises of a universal base section onto which the rifle specific offset tip is threaded. The tip is supported by a stainless steel pin which stabilizes the longer nozzle to prevent vertical movement. This ensures the BB is seated consistently when chambered which promotes higher levels of accuracy. The front cylinder is designed with dual pin tracks allowing the F2 offset to accept nozzle tips which are offset to either the top or bottom without requiring additional components.

What is F2?

F2 is essentially a Mini Fusion Engine. It offers the same adjustability and performance as the Fusion Engine in a cylinder sized package.

Patented Dual Solenoid Design

The dual solenoid design of the F2™ provides the same functionality as the legendary Fusion Engine™ but in a more compact, efficient and flexible design. Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for unparalleled control over both the loading time and air volume used. Additionally, this makes it possible to change the firing sequence giving it the ability to operate in both true closed bolt as well as "AEG" mode.

Increased Efficiency

The F2™ incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine™ poppet. This valve is able to operate at lower pressures and uses less air volume to function which optimizes air efficiency. The standard F2 poppet is equivilent to the Red Low-Flow poppet of the Fusion Engine.

Spring Loaded Nozzle

The F2™ nozzle is spring biased forward which provides a consistent loading force regardless of operating pressure. It shares the same spring as the Fusion Engine™ with both light and heavy spring options available to adjust the loading force. The robust design of the F2™ allows for an operating pressure range of 45psi to 145psi which enables it to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.

Please note that instaling a HPA drop in system is recommanded for skilled gunsmith only. The product comes as a spare part and does not come with installation manual. By purchasing an HPA system you take entire responsability of the assembly and upcoming results. For products delivered with a trigger board, contactors / switch are not guaranted by the manufacturer in case of break. We advice to take extreme care when installing the selector plate in order to not break the button. Regarding the trigger switch, it is recommended to block mecanicaly the trigger once the the trigger switch is activated to avoid excessive pressure on it.
