I got the MIDA Multi-Tool, an exotic Sout Rifle from a purple engram recently; the Cryptarch and me are tight I think, m8's r8s I think.
That said, I'm not sure how best to put the Scout Rifle to use... the gun's upgrades aren't particularly exciting. I can see radar while scoped with it. The gun's named upgrade let's me move faster and let's me fire the gun on a hair trigger; not really sure what this actually means since I've not unlocked it or used a weapon with the "hair trigger" bonus before.
I guess I'll keep hold of it for when I need something with more range than my Monte Carlo
This makes me sad. I'd sacrifice my first born* for an exotic scout rifle.
*I would like one but I don't think I'd go as far as murdering my offspring. Maybe I'd give him a Chinese burn or nip the back of his arms (He's 15 BTW. Not that I'm condoning child abuse or anything)... I'll just shut up now.
