I just threaded my bolt handle and installed an EGW tactical knob on my short action 700. Looks and works great, but when cycling the bolt fast the bolt sticks at it rear most position. Probably due to the extra leverage from the longer handle. Do you guys think it has to do with the bolt stop or just because the extra leverage kinda tweaks the angle of the bolt and it sticks from friction? How can I help this? Polishing the rails at the back of the receiver? Add dry lube? Graphite?
