Guillotine | CNC Hop-Up Arm & Nub for VFC M249 GBB

The stock hop-up arm on the VFC M249 gets the job done, but it's not exactly precision-engineered. The Guillotine CNC hop-up arm and nub is a direct replacement that gives you more consistent BB pressure across the bucking, which means more predictable backspin and better performance at range.

Guillotine Airsoft makes parts for platforms with little aftermarket support, and the M249 is one of them. If you're running a VFC M249 seriously, this is one of the first internal upgrades worth doing.

CNC machined from 7075 aluminium. Drop-in fit, no modifications required.
