Schuyler plucked a newer looking piece from the rack, and walked away from the group. He was more interested in the workings and how it fired, than he was how all the parts went together. He just wanted to shoot some stuff.
He started taking pieces off of it, and setting them aside, noting where each piece went, and keeping entire assemblies together. The action, the handle, the slide, the springs...he made sure that he had them all where he could remember how they went back together.
After he had stripped the weapon, he reassembled it, dissassembled it, and assembled it once more. After having done it once slowly from trial and error, along with memory, the second time was much faster, and he was far more comfortable with how it went together.
He took his newly aquired weapon and sighted down range towards the blank wall. He lined up the sights, moved the weapon in a small circle, keeping the sights aligned. He lowered the weapon to the "ready" position, and then quickly re-aligned the sights with his eyes, ready to fire. He repeated this several times, each time working on his grip on the weapon, the way his cheek weld matched with the stock of the rifle, and how relaxed he was with the weapon in his hands.
He would much rather have more range...killing something from a mile away appealed to him for some odd reason. He lowered the weapon, and waited for the next instruction.
