Selling my Blackout Airtac ESG with a Polarstar F2 engine. It’s a fully upgraded build ready to dominate the indoor or outdoor field. This rifle is equipped with an Airtac Polarstar F2. The F2 engine is the best HPA engine on the market, it’s a combination of the Polarstar Jack simplicity, F1 air efficiency, and Fusion engine customizability, consistency, and accuracy. It shares the same duel solenoid design and close bolt nozzle as the fusion engine which allows for variable FPS, high RPS, and overall fantastic performance. It’s paired with the best Hopup in the market the Maxx me pro which is also from AirTac. It has a black leaf trigger board allowing for a clicky trigger as well as a working safety. Because this is a competition rifle it has a working safety and is semi locked, full auto is accessible through the FCU. The F1 firearms body, the ssg1 barrel, the gearbox, is all metal. The ESG grip is 3D printed and houses a Polarstar MR regulator. Shoots 400fps at 120psi but can be lowered to 350fps at 90psi with a .25g bb. It’ll also shoot 75rps on full auto.
