This is a Built 9mm Red Carbine. It’s a rifle made for both CQB maneuverability and long range accuracy. If there’s anything you’d like to change or upgrade on the gun before you receive it we can make it happen. Different trigger, upgraded hopup unit, different polarstar engine, we’ll do it for you.

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

Details on the gun:
It’s a full polymer body which is extremely comfortable to hold. 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 300-400. Only issue is the rail doesn’t have an attachment point, meaning it’s held on by the clamp of the peqbox in the pics. Comes a shown but without attachments or magazine. Tracer unit, battery charge, battery, fcu, airtank, regulator, and line can be added for extra.
