The Remington 12 Ga Cantilever Scope Mount Assembly For Remington 870 provides a rigid, barrel-mounted platform for optics on the classic 870 shotgun. Machined from lightweight aluminum and finished in natural silver, this one-piece cantilever rail attaches directly to compatible 12 gauge barrels that are factory-cut for a cantilever mount, helping your scope stay zeroed even when the barrel is removed for cleaning or transport.

This dedicated scope base is ideal for slug barrels and optic-focused setups where consistent alignment and reduced weight matter. The extended rail section offers ample room for positioning your scope to achieve proper eye relief, while the integrated mounting holes accept standard 6-48 screws (not included). Whether you are setting up a precise hunting shotgun or a range-ready slug gun, this Remington factory assembly reflects the brand’s long-standing reputation for practical design and dependable performance.
