SLR Rifleworks LT Gen 4 SD9

The SLR Rifleworks LT Gen 4 SD9 ASTER is an AEG rifle developed by Lancer Tactical in collaboration with SLR Rifleworks, built around a robust metal alloy body and a compact M-LOK handguard design. The short 9" form factor makes the replica well suited to CQB and tight indoor environments, where fast handling and precise aiming are decisive, while the monolithic Picatinny rail leaves room for sights and other accessories.

Many AEGs on the market offer either high performance or easy adjustability – rarely both. The built-in GATE ASTER 2 Bluetooth control unit solves exactly that: you can fine-tune fire mode, trigger response and motor control directly from an app, without stripping the gearbox. That makes the replica attractive both to competitive players and to anyone who wants a reliable, tailored setup without mechanical tinkering.

Top-class electronics and precision build
The SD9 ASTER combines programmable Bluetooth electronics, a reinforced Gen 4 gearbox and a tight-bore barrel, giving a replica with high accuracy, stable performance and scope for in-depth personal tuning.

• GATE ASTER 2 Bluetooth MOSFET: Programmable electronics controlled via an app, where fire mode, battery protection and motor characteristics can be adjusted without opening the gearbox – a clear advantage over traditional mechanical triggers, where adjustment means stripping the gun.
• Gen 4 gearbox with 16:1 gears: The reinforced gearbox generation is designed to handle higher loads and reduce wear under intensive use, and the gear ratio together with the 25,000 RPM motor gives a responsive rate of fire.
• Adjustable Quantum Trigger: The trigger can be fine-tuned for both pre-travel and travel, giving a more consistent pull than fixed standard triggers and improving reaction time in CQB.
• 6.03 mm tight-bore barrel with adjustable CNC hop-up: The narrow bore combined with a rotary CNC hop-up unit gives a more stable BB trajectory and better grouping than standard barrels, without compromising range.
• M-LOK handguard and monolithic Picatinny rail: The CNC-machined M-LOK handguard gives flexible mounting for grips and lights/lasers, while the continuous Picatinny rail ensures solid, twist-free mounting of sights.

Maintenance and safety
As the replica uses a Deans connector and a programmable MOSFET unit, always use the correct voltage and a battery type compatible with the ASTER system to avoid damaging the electronics. Store the replica with the battery removed when not in use, and regularly check the battery connector and insulation for wear. As with all AEGs, keep the safety on whenever the replica is not in active use, and wear eye protection at all times.
