Most HPA guns started life as something else. This one did not. The ARC-1 was drawn as a high pressure air platform from the first line, machined out of aircraft-grade T6 aluminium end to end, and it runs a hoseless bolt drive of ARC’s own design. There is no donor gearbox shell in it and no compromise made to fit one.
The air side is what sets it apart. An integrated on/off ASA means the bottle mounts to the gun and you can degas it in a second, swap bottles safely, and never think about a remote line again. The high-pressure regulator sits in the grip frame where you can reach it. Other guns put the bottle on the gun; this is the one that gives you a valve to shut it off with.
Efficiency is the quiet argument for it. ARC quote more than 3,000 shots from a single 48/4500 fill, running at 100 PSI for around 1.2 joules on 0.20g. For a speedsoft gun that is a whole event on one bottle, and with no board and no battery there is nothing to go flat halfway through.
What you need to run it
| Item | Notes |
|---|---|
| HPA bottle | The only air kit you need. Output pressure up to 850 PSI — see HPA tanks |
| Regulator | None. A high-pressure regulator is built into the grip frame and adjusts from there |
| Air line | None. The bottle screws straight to the gun through the integrated ASA |
| Battery | None. The ARC-1 is fully mechanical — no board, no solenoid, nothing to charge |
| Magazines | Standard M4 and AR-15 pattern — see AEG magazines |

Good to know
The hop-up is a fly wheel unit and it takes industry-standard buckings and inner barrels, so you are not tied to ARC for consumables. It also interchanges with the Maxx M1 system if that is what you already tune with.
Everything strips without tools — outer barrel and body both — which on a gun with no wiring and no gearbox means getting to the bolt and the hop is a job you can do between games rather than on a bench.
Frequently asked questions
Do I need a regulator and a line? Neither. The regulator is built into the grip frame and the bottle screws directly to the gun, so a bottle is the whole air kit.
What does the ASA actually give me? A shut-off valve between the bottle and the gun. You can degas before stripping it and change bottles without dumping the whole system, which nothing else on our shelf lets you do.
Is there anything electronic in it? No. No board, no solenoid, no app and no battery. The trigger acts on the valve mechanically, which is why there is so little to go wrong with it.
What bottle should I run? Anything with an output pressure up to 850 PSI. A 48/4500 is the size ARC quote their efficiency figure against.
Can I tune the trigger? Yes, more than most. Pre-travel and post-travel both adjust, the trigger face is magnetic so it swaps without tools, and the guard comes off if you run a blade.
