Ergo key mod vfg - Ergo KeyMod Mini Max Vertical Forward Grips

I was drawn to this VFG because of its small size and minimalist design. Personally, I really like the grip but
found a problem installing it on my Samson Evolution key mod rail. The Samson rail has a slight curvature at the 6pm
position through the key mod section. The ERGO grip being a one key mod contact point made for an unstable lock to the rail. Now this is at no fault of the ERGO grip nor the Samson rail but just thought it was something you should consider when making your VFG choice. I chose then to use the ERGO grip on my Noveske NSR rather than the Samson EVO.
The Noveske NSR has a flat surface at the 6pm key mod position and I was then able to have a secure and solid lock with the single key mod connection ERGO VFG to the rail with no lateral play. I'm very happy with the feel of the ERGO grip but I was unable to use it for my initial intention on the Samson EVO.
