VFC is known for their amazing M4 AEG receivers. From the light weight aluminum, CNC finish, coating and excellent QC- this receiver is perfect for customizing and building your base gun on. This is the same receiver we use on our OCAWs minus the OCAW trades.
Most standard TM Spec Version 2 gearboxes should fit which include Retro Arms, Lonex, G&P, and more. Krytac gearboxes can fit but some love may be needed to get it fitting perfectly. Also ideal for Polarstar Fusion Engine projects.
