Airsoft Shooting Swinging Target

My son wanted a swinging target to shoot with his airsoft and BB Gun. I created this target stand and swinging targets.
It has room for 3 Targets, 2 big 1 small.
I've modified the design from the first version to include the following:

• Cross bar has groove on the bottom to insert into side supports
  for added stability
  • thicker target hangers (1 snapped when removing it from bed)
  • Blocks on bottom of Side supports to reduce Horizontal movement
