Best way to zero a Bushmaster M4a1 Ar-15?

Question

I have the 300m battle sight on it now but i only got to test it to about 50 yards. i am only going to be shooting up to 200 yards. Is this a good zero for these ranges? What about the new and improved battle sight.How do you set it up? And is it better for me? i don't want to change the settings on the gun every time i switch ranges. Is it possible? Is there a better way to zero in my gun?

My Ar-15 is a bushmaster m4a1 xm15-e2s that chambers the 5.56x45mm (.223rem) with a 16 inch barrel, a1 rear sights and a2 front sights, fixed Carry handle

any help or info about the gun is welcome even if its off topic.

i wanna learn everything about this gun and good marksmanship.

overall i think I'm a decent shot but i could be better. At 50 yards i shot 1/4 inch groups or so.

thanks in advance!!!

I HIGHLY recommend that you attend an Appleseed shoot.  It will be a whole weekend teaching you the basics of marksmanship and how to put your rifle and sights to practical use.   It will work on shooting positions and techniques for getting tight groups both close and far away.
