Guys sorry to dredge this back up but I am going back to Production from Carry Optics sooooooo i need to put the factory sight pin back in. Has anyone figured this out yet (as in tricks or anything to make it easier. Scott, when you said you used a 5/64 roll pin, did you just get one and hammer it in with a punch. Does the sight hold a zero well like this. Thanks and sorry for the ignorace.
