The GATE ASTER II Bluetooth® EXPERT for G&G G2/G2H is an electronic trigger unit for G2/G2H gearboxes designed to bring a replica to a much higher level of trigger response, electronic control, and overall versatility. The official page lists built-in Bluetooth 5.2, the included Adjustable Quantum Trigger 2, and compatibility with both AEG setups and single-solenoid HPA engines; for the HPA application, a dedicated cable is required and is not included.

Its real strength is the amount of control it offers: trigger sensitivity down to an hair-trigger feel, reset/hysteresis adjustment, automatic pre-cocking, active brake, diagnostics via the GCS App, and compatibility with smartphones, smartwatches, and computers. GATE also lists a single-board layout, very low sleep-mode current draw, a smart fuse, and extended brushless motor support.

For the G2H market, this is a very strong solution because it combines modern electronics and clean installation in a single module, while supporting the advanced features serious custom users tend to want: telemetry, internet firmware updates, advanced trigger profiles, and fine tuning of the replica. The official page explicitly shows G2 gearbox version and G2H Variant, so the G2H version is correctly covered by this product.
