Ergo msr fde - Ergo Grip Modern Sporting Rifle Grips

The ergo screw that comes with the grip seems to be of a different thread than mil spec .. however I forced it in because the screw looked nice and regret it because I feel like a may have damaged my Anderson threads. I really wanted it to have a more aggressive angle but I was aware of that it didn’t not pointing fingers. Overall nice grip just the picture makes it seem like it’s a lighter Fde but it’s darker than in the pictures just a heads up
