The 510 comes with a safety that blocks the trigger, not the sear, which is a totally new design. No screws, drilling, or tapping required.
The Model 510 will bring a whole new realm of accuracy to your Remington rifle. Each trigger is geometrically identical with tolerances less than .0005”. adjustable from 1.5 to 4 lbs.
Does not contain bolt release latch, use only with 700 actions with side bolt release like the SMR 3600 series actions.
