VFC AR15 GBB Series Upgrade GuideHop Adjustment Arm

For VFC Guide-HOP Series GBB (MK18 /URG-I /SR-16 E3)

The original VFC hop up arm tends to lack performance, especially when using big contact surface bucking’s.

This Product combined with the right bucking will increase the hop effect applied to the BB due to the spacers increased contact surface to the bucking, which results in better lifting performance especially when using heavy BBs (>0.4g).

We recommend the usage of bucking’s like the Begadi GBB5/VSR5/VSR7, Flamingo VSR, Modify X-Range, Maple Leaf MR or TNT TR-Hop

Recommended bb weight / power output combinations: 0.36g+ at 1.5J, 0.45g+ at 2J

Adjustment will be more precise/sensitive than with the original arm. Especially with ligher bb's.

Includes 1x 3D printed PA12 nylon curved spacer and 1x stainless steel pin
