**All kits come with a Filter Fitting installed, FCU, Switchboard, Wire Harness and any additional components needed to convert the specific airsoft rifle model for which the kit is configured. The HPA Tank, Air Rig (regulator and line) and Battery needed to operate the system are purchased separately.**

 

Winner of the "Best HPA Engine" in the 9th Airsoft Players Choice Awards, 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. (PolarStar Filter Fitting now included)

 

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.

A robust design allows for an operating pressure range of 45psi to 145psi which enables the F2™ to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.

Additionally, its 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.

Gel Ball Compatible

F2 HPA conversion kits can also be configured for use in gel ball systems.

Please contact us for information on ordering F2 systems for gel ball use.

 

Velocity: 480fps w/ .20g @ 145psi
The F2™ allows for easy velocity adjustment just by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 480fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum velocity while shorter barrels will decrease it. 
ROF: 30rps
The maximum cyclic rate of the F2™ is affected by several factors such as the operating pressure as well as quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations.
Air Efficiency: 1000+ shots from 13/3000 @ 1.5J  w/ .28g
The standard F2™ poppet valve is equivalent to the Red Low-Flow poppet of the Fusion Engine™. However, this valve responds faster and requires less air volume to operate so the F2™ is able to achieve greater air efficiency than even a finely tuned Fusion Engine™.
(Test Configuration: Red Poppet / 6.05x375mm Barrel)

Very sturdy toy
Color: Blue
It’s very sturdy and has a surface and handle that allows a dog to grip on for a good tug. It’s also holding up to my very, very aggressive chewer and she’s 80-90 lbs.

Great dog toy!
Color: Green
This is my third or fourth purchase of the same toy. My 45 lb super chewer dog loves to chew on this and especially likes to play tug of war. He is very rough on toys and most do not last longer than a few weeks. This toy lasts about 2 years - which is amazing considering my dog plays with it every day. Eventually it breaks in half during a tug of war session, but I don’t consider that a flaw or a problem because we definitely get our money’s worth of playtime! I’m happy to buy a new one every couple of years and I will keep buying it as long as it is available.

Still going strong after three months of Doberman teeth!
Color: Green
This was one of the first toys I purchased for my adopted 4 year old Doberman Pinscher. It has been chewed, and chewed, and chewed some more. This is one of his 3 favorite toys when he has to go in his crate. As of yet there are no significant teeth marks, holes, or missing pieces. It is solid rubber, light weight compared to a similar toy he has, and just the right size to carry around in his mouth. He seems to enjoy the sensation the little rubber nubs have on his gums when he chews it. We have also used this toy to play tug of war and fetch for the same reasons listed but also because the neon green color is easy to see especially if the dog gets distracted and leaves it in the yard. When playing fetch the weight of the toy does not lead to rotator cuff surgery with repetitive throwing on the part of the dog's human! When it gets too dirty and slimy for my tolerance, it is easily washed in the laundry room sink with dish detergent and a sponge always returning to its Spic n' Span original appearance. If and when he chews this one up, I will not hesitate to replace it. Top 3 Likes: -Sturdy, holds up to chewing, used as a crate toy as it poses no threat from dislodged pieces -Bright color aids in finding it outside -Comparatively lightweight, easy to throw, and easy to clean Top 3 Disikes: -Potentially an aggressive chewer could dismantle Only 1 dislike!
