Home Forums Hunting & Shooting Gunsmithing Opening the feed rails on a M700

On the theory that monkeys just shouldn't be fücking footballs in my shop.... I ditched my first method (which was gonna work, dammit! ) and made something similar to what AJ has pictured there.





The gizmo/stop on the front is a much lamer way to clock the bolt than AJ's 45 degree (?) angled ramp, but it works.



Below, it's in the vise with a PTG/M16 bolt I used to set the height of my clocking stop. I made a "key" that sits tightly in the milled extractor slot, then eyeballed it to vertical against a ground test bar in my mill chuck. That what's happening here. Once clocked to vertical I slid the gizmo into contact with the lug and tightened it down. It seems to repeat "perfect" (yeah yeah yeah) but I'll check that more rigorously before I cut anything.



I think I have now overkilled this one to death and can cut the slot in the ONE BOLT I'm planning on modifying.
