Here I have for sale my what originally was a Specna arms H20 AEG M4 rifle, full metal with 10” M lok rail. But with all AEG components removed and the rifle is now powered by the Polarstar jack HPA engine which is only a few weeks old.

This rifle has been fully upgraded. It has:
-CNC GATE EON rotary hop up unit.
-Prometheus purple hop bucking
-OMEGA nub
-6.03 Tightbore barrel
-Polarstar Jack HPA engine with FCU (full auto RPS is crazy speed)

This rifle shoots lasers, very consistent FPS, Very accurate, can overhop 0.43+ BBs. sounds great and silent. Programmable FCU (loads of vids on YouTube) no issues or faults whatsoever other than dust cover doesn’t close but a new one is like £5.

Very fun to use, reliable HPA engine. Only selling due to using my GBBRs more instead.

Comes with box, HPA mini lipo battery, 2 Specna arms mid cap mags, all attachments and M lok angled foregrip (seen on photos)
