Everything you need and nothing you don't - Magpul Industries M-LOK Angled Fore Grip

As the picture indicates there isn't much there in the way of weight. If you go with a mlok handguard with only rail on top the beauty of this AFG is that you don't need to attach a rail section to the bottom of your mlok handguard. This saves weight at the end of the gun where you want to save weight.

I have actually replaced AFG's on all mlok handguards just to get rid of the weight of the rail secrtions that I don't need so I can use them on other things I may need.
