Nice rings! - Weaver 1 inch/30mm 6-Hole Picatinny Rings

I bought these to mount a large optic (6-24x50) on an m14 with a brookfield type mount. They are easy to install on a picatinny/weaver system. Just make sure you use a pattern to tighten them in little increments kind of like you would to install a head on a car engine. I've fired probably 500 rnds through the rifle and have not noticed any kind movement at all from the scope. If you plan on lapping these rings they do pose a slight difficulty because of the 6 hole system. I would be very careful to make sure you're getting consistent pressure on the whole ring and continue to torque the screws as you lap.
