Did it fall out of the receiver OR did it pop off the muzzle while you were mortering the rifle and went flying near where the brass landed? Did you just take the muzzle device off or did you remove the crush washer also?
Hope you ordered at least a 20MOA rail. That gun will shoot a lot farther than the scope adjustments that is in the scope. I put a 50 MOA scope rail on mine. That let's me dial elevation for a mile.
We got enough rain for a good crop of beans. 1 pond mostly dry. 2 ponds a little low but plenty of water. and 1 small pond that's spring fed. It's full.
