Recently I purchased recurves for my grandkids and a 45 pound recurve for me to play with them. No sights just the bare bow. I have spent years shooting bare bow but gravitated to the compound bow and rifle for longer distance hunting accuracy.
Shooting instinctive, barebow there are no sights but you can train yourself to see the sight picture as a gap that your brain can calibrate to. Point, draw/aim and shoot. As a youngster I learned to shoot split finger where the index finger was above the arrow knock and two fingers below. Drawing back the bow so my index finger touched the corner of my mouth as an anchor and then released. This worked ok but I found that shooting tight groups accurately helped to shoot three fingers under the arrow. As you can use the arrow to sight down it. With training you can be a great shot but it takes dedication.
I use a technique called “Walking the String” some call it Apache Draw, here you place your three fingers under the arrow, then use your thumb to mark where the split in the finger tab is. About an inch below the arrow. Draw the bow an inch below the arrow, then use the arrow to sight the target. You can angle or cant the bow a bit if it feels and sights better. Secondly you can use a stance that is quartering toward the target with your feet a shoulder width apart with your knees slightly bent and loose like a spring. Set your distances at 15, 20 and 30 yards and establish your form and accuracy at 15 yards then 20 etc.. I use helical 4 inch feather fletch arrows as I will later put broadheads on them.
Now practice, practice, and practice.
Good Shooting!
