HLS MNT 509 ADAPTER RMR/HS507

Description

The Holosun 509 Adapter is an optic mount.

An optic mount holds the sight to the rifle. It sets the height of the sight above the bore, and on a rifle that height decides how the sight line and the bullet path cross.

Two things have to match: the mount's ring or footprint has to fit the optic – 30mm and 34mm tubes are different, and Aimpoint, Trijicon RMR, Leupold DeltaPoint and Holosun K footprints are all different – and its base has to fit the rifle's rail.

Torque the fasteners to the maker's figure with a wrench that reads in inch-pounds. Over-tightening rings damages a scope tube.

This is a part or accessory, not a firearm, and ships directly to your address.
