Tearing into my first left-handed rifle build has been interesting to say the least. The rifle is ejecting the brass while cycling the bolt 100%. The problem i run into is when I mount the NF 5.5-22x56, the case mouth contacts the bottom of the side focus knob and almost knocks the brass back into the bolt raceway. Is there any way around this besides running a scope with a smaller side focus knob OR M16/Sako extractor?
