Have an extra couple hundred dollars laying around? Can't decide what to spent it on? Well, look no further, I would be happy to relieve you of that pesky money in exchange for this custom built Polarstar m4. Fairly plain externally, though the receiver has full red jacket trades, which I have never seen another set of. Internally sits an Amped custom V2 Gen 3 Fusion Engine, running a purple nozzle, gold poppet, lightning banjo, and amped igl. I had it tuned by Polarstar themselves, and it will run about 900 shots out of a 13/3000 (more than double that of a stock engine). Additionally are an slp Reg, amped grip line, and choice of tank (13/3000, 62/3000, or pretty much whatever size you want) I do have a set of drop on rails that might fit, I'm not sure on that, but if you are interested let me know. If the crane stock is too bulky for you I have an le stock I could throw on instead. Asking $700 or best offer for everything, cash is preferable, only trades I'm looking for right now are a drop in hpa system, v3 fusion engine, or a cz 805 Bren. Thanks for taking a look, feel free to message me for more info.
