- Perfect Spare Set
- All Metal Shims Set
- Set of 0.1 and 0.2 Thin Shims
A pack of shims with two degrees of thickness, useful for ensuring your gearbox turns over as smooth as possible.
- Optical MOSFET
- Gate Quantum trigger included
- Pre-upgraded to Expert Firmware
If you're running an SMG-5, M4/AR-15 or any other AEG which uses a version 2 gearbox, the GATE ASTER™ MOSFET will take your AEG to the next level. This advanced electronic trigger unit replaces your conventional trigger contacts with optical sensors, allowing for 250 different trigger sensitivity settings, burst and binary fire modes and a plethora of other functions to be programmed in using either the trigger and fire selector or the Gate Control Station App.
This set also includes the Gate QUANTUM CNC trigger which is compatible with M4/AR-15 AEGs but unfortunately won't work with SMG-5 or G3 platforms. When installed, the Quantum trigger offers 250 trigger sensitivity options via the ASTER's optical sensors. Constructed from CNC-machined aluminium, the Quantum both looks great and allows the ASTER™ to take full advantage of its optical trigger sensors.
This is the MOSFET we use in our Bolster Tuned platforms due to its fantastic balance of cost-effectiveness and performance, offering incredible efficiency improvements even before you get into the programmable features and customisation options. As with all ETU/MOSFET systems, a certain amount of expertise will be required to install the ASTER™ so if you're not confident, we suggest seeking a technician to carry out the installation process for you. If you're ready to take your AEG's performance to the next level, you're ready for the ASTER™
- Rotary HOP-Up Adjuster
- CNC Aluminium Construction
- Includes flat & conventional HOP arms
If you're building your M4/AR-15 AEG to focus on range, accuracy and efficiency, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG belongs in your build. This set is a full replacement rotary type HOP-Up unit for version 2 gearbox-equipped Airsoft M4/AR-15 platform AEGs and includes all of the parts you'll need to replace your stock HOP-up unit. The set also includes the choice of two HOP-up arms, one designed for flat HOP setups and one for conventional.
As with all internal upgrade parts, we only recommend this HOP-up unit for the technically proficient as it requires full assembly and does not include a HOP-up rubber or HOP-up nub. That said, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG is widely regarded as one of the best options out there for the pros, and when set up properly, it has the potential to outrange anything else on site!
- Flat diamond contact patch
- Designed for accuracy & range
- Compatible with most Airsoft AEGs
If you're looking for all-round improvements in your HOP-up performance, the Maple Leaf Macaron HOP-up Bucking is calling your name! Designed to fit Airsoft AEGs and enhance both accuracy and range, the Macaron boasts a flat diamond-shaped patch for greater contact area with your BBs, giving a "Flat HOP" style effect when paired with an OMEGA or OHM HOP-up nub.
When compared to the Monster HOP-up bucking, the Macaron's contact patch is slightly less prominent, designed to provide a balance between range and grouping size as opposed to the Monster's focus on pure range. Compatibility-wise, the Macaron should fit most Airsoft AEGs though some level of expertise is required for fitting and tuning. If you want tighter groups and more range, the Maple Leaf Macaron HOP-up Bucking for AEG will do the trick!
