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
Compatible with VFC Guide Hop AR15 series
Material: 7075 aluminum
Production method: CNC
Surface treatment: Oxidized

Product Characteristics & Cosmetic Standards
Our products are manufactured using precision machining and industrial finishing processes. As a result, minor cosmetic characteristics may be present, including but not limited to light machining marks, tool traces, finish variations, minor surface marks, slight discoloration, or light surface oxidation where applicable.
In mechanical systems, slight movement, wobble, or play between components may occur due to designed tolerances and does not affect function or performance.
These characteristics are purely cosmetic or tolerance-related, fall within normal manufacturing standards of the airsoft industry, and do not constitute a product defect.
Returns or warranty claims based solely on such cosmetic or tolerance-related characteristics may therefore be declined in accordance with our return policy.
Light surface oxidation (rust), where applicable, is a normal material property and can typically be removed through routine maintenance (e.g., WD-40 and a soft brush).
This notice does not limit any statutory consumer rights.

Had the classic right hook on my vfc v3 mk18. This Arm solved the issue and gave me better groupings and range!
Well built and very functional. One of those things that form meets function.
