The fantastic thing about power ring constructs is that there's no need for them to pick up speed. You can have something the size of bus going at lightspeed as soon as it's willed into being.

It was not even a question of whether or not the sniper would make it in time. It was more 'will Alexander's shot be true?'

Jason watched, using a pair of construct binoculars. It was practically flawless. Kim probably couldn't have made the shot like that, and her bow was magic. "Yeah!" The Sinestro Corps sniper didn't have time to raise a barrier, the arrow split his rifle in half and kept going, taking him full in the shoulder. Judging by how it carried him on, Jason didn't think that he was conscious. He'd probably be traveling until someone picked him up.

When he turned to celebrate, however, he got a good look at Alexander. A better one than before. And his fellow Legionnaire did not look good. "Hey, man. Are you okay?" He holds out his hands, unsure of what to do about this. That is an alarming amount of red on his armor.
