Description:

The Arrow Sentry Turret is a compact, single-block automated defense that detects and fires arrows at hostile mobs within a 24-block radius. Place it where you want protection and right-click the turret to toggle it on or off; when active it automatically scans for the nearest hostile and fires roughly once per second while playing its firing sound. If you want the one-block turret to have a different look or size, just ask.
