    Description

    Package includes: Gun, tank, line, regulator, full size FCU, a 7.4v battery (not pictured), approx. 2500 0.25g BB's, two midcap hex mags w/ mag clamp, detachable silencer, replica EOTech sight, iron sights, angled foregrip, laser, flashlight, charger for flashlight (not pictured), and a speedloader (not pictured).
    Essentially, everything you need to go out to your field. Due to shipping rules, I have to ship the tank with low/no air in it.
    For sale is my custom built HPA Airsoft Gun. I've been working on airsoft guns for about seven years now, and this is undoubtedly the best gun I have ever built. The F1 shoots between 300 and 500 FPS with 0.20g BB's, which is controlled by the regulator, of course. The highest RPS I have achieved with this gun is 55 RPS, but I know it can go higher with the right mag + FCU settings. I just don't have the time and resources to make it happen. Not to flex, but the range on this gun is one of the best I have ever seen from any non-sniper/dmr build. I usually have my reg and FCU set so the gun fires 375 FPS with 0.25g BB's, and I can easily reach people from all the way across my local field. Unfortunately, I don't have an exact range estimate for you in feet/yards, since it varies depending on your regulator settings and BB weight, but rest assured, it shoots far.
    Below are the details on the parts I used in this build.
    I started with a Gen III DBoys's Scar-L, because I liked how the aluminum upper reciever looked. From there, I gutted the internals and replaced it with the following:
    - Polarstar F1- Angel Custom Tuneable Trigger
    - Flat Hopped Prometheus 6.03 Barrel w/ Prometheus/Laylax Bucking + Nub Combo
    - Aftermarket Selector Gear by AGM (the stock ones are notoriously flimsy)
    - Braided Wire Harness, if people still care about that(This gun uses the full size P* FCU, not the mini/trigger FCU.)
    In terms of external additions/modifications, I did the following:
    - Gas Block Delete (looks much better in my opinion, doesn't affect functionality as it is purely cosmetic)
    - Magpul Angeled Foregrip
    - EOTech Replica from aliexpress lol
    - Mounted Laser with pressure switch (takes CR123A batteries)
    - Mounted Flashlight with pressure switch, toggle switch, and rechargable battery (includes charger, charger not pictured)
    - Ares/G&G Iron Sights
    - Iron sights, laser, and optic are all cowitnessed
    - Detachable suppressor with birdcage flash hider
    A standard tank, line, and reg combo is included. The tank is a standard 3000psi, 48cu tank. It was last hydro tested in March 2019, as shown in the photos, meaning it has until around March 2024 before it requires a new test.
    A rant about FCU settings, for my fellow techs:
    - The dwell poppet (dP) is currently set to 60. While dP is a global setting, what most people don't know is that the firmwares of the FE/F2 vs the F1/Jack actually use different conversion formulas when converting dP into increments of time. If dP stands for the dwell poppet's setting, and t stands for time in seconds that power is applied to the solenoid, the formula that the FE and F2 use is (t = dP  * 0.01.) The F1 and Jack's formula isn't actually known. It isn't listed anywhere on Polarstar's website. Why? I don't know. So, I had to find the optimal dP the old fasioned way. I got out my chrono and set dP to max. From there, I began to decrease the dwell in 1 unit increments, while firing 5 shots per increment. Once the averaged FPS between the 5 shots began to fall, I undid the last increment. Keep in mind that dwell indirectly controls the air volume passing through the solenoid by controlling the length of time that the solenoid is open for. By setting the dwell as low as possible without losing air volume/FPS, it should mean that the system is as air efficient as it can be.
    So yeah, rant over. If I forgot anything, or if you have any questions, shoot me a message. Shipped with UPS Ground.
    Disclaimer: This is a replica firearm that shoots non-lethal projectiles. This replica cannot be modified to shoot live rounds in any way. The included suppressor is built specifically for replica firearms, and cannot be modified to fit real firearms in any way. I have to put this here so I don't get blown up by Ebay's content policy.
