Ok so,

For sale is this painted, unbranded (believed specna arms) M4 with upgrades inside. This was a spare parts build so being sold as boneyard. It is fully working, however the switch between semi and full auto is temperamental. 

Inside it has a perun V2 mosfet, wired to deans. Swiss cheese piston with aluminium piston head. Rocket airsoft nozzle and I believe short stroked 12:1 rocket airsoft gears. It also has a tight bore inner barrel, believed to be ZCI. It has a G&G high speed motor which has come from an ARP9. Fully shimmed.

The upper and lower are Polymer, but the front is full metal predator clone. Front grip is full metal. The upper and lower has been laser engraved.

There is an aster trigger which looks nice. The trigger guard is metal from an ARP9. Iron sights are full metal and are from G&G. The stock is sprayed G&G also. The bottom rail of the front handguard is 3d printed and can be easily removed.

Rifle is shooting at 1.1J and is site legal. Gearbox is fully shimmed. There is damage to the outter barrel underneath where previous owner of the part had gone at it with a drill, but this doesn't effect functionality and can barely be seen.

Red dot sight is cracked but turns on. I think that covers everything. Still loads of good parts, the perun is brand new inside as this was a spare parts build. 

Any questions please ask. £160 ONO.
