This is a Fully Built Colt M4A1 Polarstar Jack. It’s a rifle made for both CQB maneuverability and long range accuracy.

About The Internals:
The rifle has a Polarstar Jack installed to power it. It’s the go to engine for many HPA users because it’s 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 best Hopup unit on the market, the maxx me pro, as well as a tight bore inner barrel

Details on the gun:
It’s a full metal body which is extremely comfortable to hold. The whole build has been fielded about 3 times. It has a finely tuned speed trigger to make shooting fast super easy. Shoots 400fps at 100psi with a .25g bb and up to 60rps. FPS range is 320-440. Comes a shown but without attachments or magazine. Tracer unit, battery charge, battery, fcu, airtank, regulator, and line can be added for extra.
