Ring Beam Units are small, swiveling turrets installed in the BOTTLE SHIP's Bioweapon Research Center in Metroid: Other M, where large numbers of the machines have been installed in a few corridors leading to Room MW. They are completely indestructible, and every few seconds will fire Rinka directly at Samus Aran.
The Rinka move slowly but cause severe damage, and are more than enough to distract Samus from opening the many Multi-Lock Blast Shields blocking the path ahead. In addition, these particular Rinkas have lost their ability to pass through solid surfaces and instead bounce off of them, making them more dangerous. Samus can destroy them using her Arm Cannon or Screw Attack. If two such projectiles collide both will implode and vanish.
