You could see the two regs, my 1.7V line reg "broke" so I had to get a new one. Also, after envying SS of his Leatherman multi-tool thing, I got me one. A bit of a cheaper one, but they didn't have the Charge in stock so I got this one instead.(Its still awesome tho )
You could see it laying there like a boss in the pics.
Well, caliber and a caliper are two different things, I'm not sure if you are going to shoot up a school or take some measurements. I'm just going to assume caliper.
