Full credit goes to Pastaga, who created the Krogan Graal. I am just sharing so others can enjoy it.
Modified: Instead of the original 4 MS muzzles, it now has 1 Shotgun muzzle. And the Rifle Grip was replaced with a Shotgun Handle. This conversion makes it compatible with newer a0.9+ versions. And a Final Attack of 289.0 is extremely good for a shotgun - far better than any I've found. (The best I've seen had a FA of just 225.1.)
