Selling my little tan sleeper Polarstar jack build. If you looked at it from the outside you’d like it’s just your average polymer m4 that you got at an evike clearance sale. But take a look at the internals and you’ll see this rifle means business. It has a tuned speed trigger so you can absolutely spam the trigger with no issues. The HopUp and barrel assembly ensure that your bbs are getting to your target as accurately as possible. And being powered by a Polarstar jack this rifle shoots 400fps with a .25g bb at 120FPS and shoots over 60 rounds per second on full auto. FPS ranged from 290-400. Great build for anyone looking for a lightweight powerful m4. Comes exactly as shown but without flash hider and magazine. Tracer unit, battery charger, battery, fcu, airtank, regulator, and line can be added for extra.
