3FTech Gripstop by FFFTech/FFFTechnology
Is it a undersized foregrip? Is it an oversized handstop? I don't know to be honest, so I'm just gonna say it's both! The foregrip/handstop/wHat has ridging down it's front to allow the support hand to rest against/grip the design with greater traction than say, if it was smooth.
