I wouldnt change a thing until it breaks. Its not what I would want for my own, but I wouldnt leave it behind. If you practice and learn how to shoot, a bullet in the brain box from a 1:9 or 1:7, is going to put an end to the story. In the mean time spend money on practice ammo.
If its functioning, dont worry about the M4 ramps either. My SBR doesnt have them and I have over 5K rounds including a bunch full auto lately without any problems.
How far you can accurately shoot, depends on you more than anything. I have a "match" barrel on my SBR, and I know I could hit a human sized target at 600yds with my EoTech using MK 262. I'm sure yours is more than accurate enough.
I'd suggest you try another persons SBR with a Krink. It works for what it is, but its also a half pound on your muzzle. Be honest defining your requirements and you'll be happy with your choices.
