Verkaufe hochgetunte Arcturus CQB AR15 HPA Cobalt Kinetics Green

I am offering an extremely high-quality tuned and well-maintained HPA airsoft based on an Arcturus CQB in Cobalt Kinetics Green finish.
The airsoft is fully operational, perfectly adjusted and has shown top performance in every respect.
Selling because I'm likely giving up the hobby—not an easy step, as this setup was my absolute passion project. It's been played a lot, which is slightly noticeable in the light (see pictures), but it adds a bit of flair. It doesn't have any deep scratches and is in good condition.

⚙️ Technical details & highlights HPA system:
Wolverine Heretic Labs Special Edition Engine (based on Inferno Gen 2)
FCU: Perfectly tuned by the technician – dwell time & settings ideal.
Safe Semi-Semi – meaning semi-only across both firing modes. Delivered as professionally optimized.
Gearbox: Retro Arms CNC HPA Gearbox
Hop-Up & Barrel Setups (2x): (Perfectly tuned by the technician)
- Specna Arms x MAXX CNC Hop-Up (identical to MAXX models), Mapel Leafe Bucking + tuning barrel
- Begadi Neptune Hop-Up Unit + shortened DaVinci barrel with Mapel Leafe Bucking & Omega Nub Tensioner

🎨 Appearance & workmanship
Cerakote Coating (Cobalt Kinetics Green) professionally applied by Bad Agency
→ significantly more robust than factory coatings
→ provides a classy, matte-tactical look and integrates perfectly into forest and outdoor environments.

⚖️ Weight & Handling
The weapon has been optimized for weight in every area: It's almost as light as an APC (2.4 kg with red dot and raiser). The only original parts are the body, buffer tube, outer barrel, and barrel nut. These can also be replaced with carbon parts if necessary, making it even lighter and weighing less than an APC. Handling, balance, and maneuverability are top-notch—it even shoots slightly better than Bad Agency's one-of-one models (I've owned one-of-one models myself). And anyone familiar with them knows what that means.

💥 Performance
- Chrono with 0.25 g BBs at approx. 120–130 PSI: ~2 joules
- With 0.30 g BBs: approx. 1.5 joules (at approx. 80 PSI)
- 0.40g BBs work without issues, and Dwell has also been set to 0.40g BBs. 0.45g BBs also work smoothly, as the hop-up still bounces reliably up to about 0.50g.
- On 1.5 J I recommend playing with slightly lighter BBs (e.g. 0.32–0.36 g).
→ Ideal for playing fields with a 1.5 J limit
→ Below 0.32 g is not recommended, as otherwise the trajectory becomes more susceptible to environmental factors such as wind. Both hop-ups can of course also handle lighter BBs.
⚠️ Note: Whether it can be reliably adjusted below 80 PSI to 1.0 J for CQB has not been tested. CQB has never been played with it. Feeding is flawless at all of the joule values tested above.
