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 VSR5/7, Flamingo VSR, Modify X-Range, Maple Leaf MR or TNT TR-Hop.
Includes 1x nylon made curved spacer.
Compatible with VFC HK416/M27 IAR series, excluding V1 (hex-key adjustment)
The hop up nub that came with the hop up arm was too wide. I had to file it down to make it fit in the hopper chamber. Would’ve been nice if it already fit.
