Looking for info/suggestions related to an AR with a Bump-fire. I put a new Bump-fire stock on an AR. The problem I'm having is the bolt does not move foreword fast. The action is very slow, hence there is no rapid fire. I have done a strip clean twice, done a visual inspection for any obvious wear/restrictions. So, the question would be, what would impede the action of the system? Or any gun smiths that are reliable for problem solving for AR's?
Thank for any input.
