Good quality handle, t nut for the mlok was plastic though - OpticsPlanet Exclusive Firefield Rival M-LOK Foregrip

The actual handle is great, good material. The weight is perfect, heavy enough to feel solid but not so heavy its adding a bunch of weight. The only thing standing in the way of 5 stars is the t-nut that is used to attach it to the rail is made of plastic. If you have some metal ones laying around or dont mind buying some its a solid purchase.
