GSI Hop-up arm for APFG MCX, increases accuracy (hop-up tensioner included)
The hop-up arm included as standard in the APFG MCX series has a lot of left-right play, which makes bullets not come out consistently.
To solve this problem, GSI improved the play of the hop-up arm for the MCX and matched it with a dedicated hop-up rubber and hop-up tensioner to create the optimal bullet collection.
This precision-engineered upgrade ensures your shots are consistent, enhancing your accuracy on the field.
