Shiro sat in his new room, absorbed in making adjustments to his weapons. A little while ago, he had gathered his belongings and moved them into Blackguard's room. Having beaten Gren and Bridget to the room, he picked the top bunk bed closest to the window and quickly got settled. Once his things had been neatly put away, he pulled out a large toolbox and unslung his weapons to begin working on them. He plopped his behind in a corner of the room. Trying to be out of the way as much as possible as he worked. Pressing hidden switches and using his tools, he swiftly broke his weapons down to their most basic parts. Neatly laying them in front of himself in an organized fashion.

As he sat there tinkering, it appeared he was more focused on removing some major internal parts. For some reason he couldn't explain, he was displeased with the hidden grenade launcher installed within his weapon. With a frown on his face, he examined the parts after he had removed them. His ears and tail twitching and flicking back and forth restlessly.

[B]"Barrel seems fine...So does its rifling and lining...Chamber is good..."[/B] he muttered as he looked down the long length of a removed barrel.
Picking up the trigger pack he made a face at it as he turned it over in his hands, [B]"Sear and hammer seem fine...Disconnector and trigger too..."[/B]
He scratched at his head, confused. 
[B]"Was it possibly the bolt carrier group?"[/B]
He puffed his cheeks out. Unsure as to why his weapons didn't perform as he had intended. 
Setting the barrel and trigger group down, he picked up the bolt carrier group and closely examined it.
[B]"Bolt face and locking lugs are good..Extractor seems fine..Firing pin is good..."[/B] He grew frustrated. Nothing seemed out of place.
He even checked the buffer and action spring. Nothing.
Ruffling his silvery-white hair in exasperation, he couldn't figure it out. [B]"Must've just been some machining or design errors...Oh, well. Back to the drawing board, I guess."[/B]
Shrugging, he put the removed parts in the toolbox that sat next to him after breaking them down even further. Some day soon, he would have to visit the school's armory or machine shop.
