PolarStar F2 M249 Player Package | HPA Drop In Kit
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 equivalent to the Red Low-Flow poppet of the Fusion Engine. 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. The F2™ incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine™ poppet.

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. The F2™ comes complete with a Fire Control Unit (FCU) that has an LCD display that allows you to tune your F2 to your liking! Adjust it's dwell, rate of fire, burst modes, nozzle feeding, and more!

Prewired perfectly for the A&K middle and heavy m249. I have the featherweight, so I was given an option for an exchange, but it was my fault. Just needed to get the trigger board and M60 nozzle (#14).

Got this for a project I was working on in which involved a M249 gearbox but it isn't an M249 or PKM. It came with pretty much everything I needed, which is good, except one thing which I'm kind of disappointed about. I was really surprised it didn't come with a nozzle for a M249 so I will have to order one separately.

With the help from the staff via the online chat I was able to make a decision on what exactly to get for my M249 and good lord, was it the right decision. This kit turned my Middleweight M249 in to an absolute beast. I went in knowing it will be a process but the final product was completely worth it. Only issue I did have was my bucking which I ended up changing and needing to Dremel out the lower portion of the gear box to make room for the air line. All-in-all the rest of the parts that came in this kit are standing up extremely well. I play MiLSiM out in Hawaii in the humid, wet conditions of Waimanalo just about 1-2 times a month and the internals are still holding strong. This on top of the amazing help and attitude of the staff made this truly enjoyable. I will guarantee be buying more products from these wonderful folks. (Bought February 1st and installed everything on February 5th[I highly recommend researching if this will be a DIY project just to make it that much easier to do])
