Chief Says : Question for you . Would you mount a scope base on your receiver , using only 2 screws ?
Personally I would not.
On the barrel " scout mount style its ok. " Usally a lighter weight
scope is used.
For large Scopes , over the receiver more than 2 screws fit the bill.
Myself , If I use the cantilever mount over the receiver I add 4
holes to it , mill the bottom for a flush fit , secure it to the barrel and receiver ( 6 screws total . ) Thats a mount.
