Retro Arms CNC V2 Gearbox

Airsoft gearboxes often use a low-grade alloy that is quickly shaped and then machined for efficiency and cost-effectiveness. However, this means sacrificing strength and durability, with a risk of defects leading to early failures.

Enter Retro Arms and their gearboxes, crafted from single blocks of aircraft-grade aluminium, making them some of the strongest in the biz!

The precise manufacturing and tight tolerances make them perfect for high-performance builds, even handling M160 springs with ease. Plus, the Quick Spring Change system (QSC) lets you swap out springs with a simple hex key, no need to open up the gearbox!

These also fit perfectly with most HPA builds and work incredibly well with Monk Builds.

Features: 

• Made from a single block of Aircraft grade aluminium 7075 T6
• Enlarged Wire routes
• Stronger threads
• Reinforced and radiused profile around the cylinder head
