Basset Machine makes the best mount,does not require removine the stripper clip guide,and it is easily removed if you want to use your iron sights,plus it will return to within 1/2 moa of your original settings when you re-attatch the scope.
Not the prettiest,not tacticool but it works.
I have a Socom 16 in a Sage EBR chasis.
