Yeah, tried that, still couldnt "kill" it without it blowing up, and couldnt "pick" it while alive, oh well, just a few thousand caps I guess, what I really need to ammo though, le sigh
I found this on the Vault:
If the overclocked turret can be disabled without exploding, it contains a large amount of loot including a LAER, a Valence radii-accentuator, and two Weapon repair kits.
So I guess there is no unique loot to find. At least you aren't missing out on much.
