GHK SIG SG553 GBB Burst with accessoires and upgrades

Selling my GHK SIG SG553 with accessoires.

Bought this here a few months ago but will stay with the AR15 platform, even if this is the most solid GBB I've ever held. The VFC stamped steel rifles seem like toys compared to this one. Literally everything apart from the grips and the top rail is steel on this rifle.

Must've been built around 2020/2021 since it already has slight upgrades like Cerakoting but retains the functional 3-round burst, which works flawlessly on this rifle. Internally it has been upgraded with a Maple Leaf Hop Chamber, Bucking and inner barrel.

The rifle in general is working like a charm, never had a problem with it. Mag doesn't leak but is missing the couplings.

It will come with 1 Samoon NPAS Nozzle, Airtac HPA adapter for AR15 AEG mags, EoTech copy, foregrip, additional handguard rail and 3D printed Picatinny stock adapter.
Edit: Second NPAS nozzle and tool have been sold separately. 

If you're interested in just buying the HPA Adapter, write me.
