Selling my Built Stuby MK18 Polarstar Jack. This is a mainly an outdoor rifle made to outshoot almost anything you’ll see on your field. The rifle has a Polarstar Jack installed to power it. This is the most beginner friendly HPA engine if you were to instal, test, and tune it yourself but if you’re buying it from me, it’s all been done for you. Has a great rate of fire and is a great pick for beginners and experienced players alike. It’s paired with the stock Krytac hopup Unit, a madbull bucking, and a madbull inner barrel which shoots phenomenally. The rifle has a tuned speed trigger making shooting fast a breeze. It’s extremely comfortable to hold and it’s a very compact build. Also has a flashlight with a top mounted pressure pad. Shoots 400fps at 100psi with a .25g bb and up to 60rps on full auto. FPS range is 300-430. Only downside is the eotech is shot out. Comes as shown with all attachments just without the magazine. Tracer unit, battery charger, battery, fcu, airtank, regulator, and line can be added for extra.
