I love the lines of the f2000 and I am very disapointed with FN for not being customer friendly to the civilian population. I have an fs2000 and I am pleased. I like my AUG a little better but I would not part with the FN. I am using an eotech 512 and want to update to the 557 whenever eotech decides to release it to the public and not just advertising it but I probably will not be satysfied. I have decided to mod an impact resistant scope cover by injection moulding in the pattern of the factory one. It will be an easy mod just havn't decided which scope to use. I have not heard anything good about the original so I think this is the best choice.
