Aimtech scope mount remington 870 - Aimtech Scope Mount For Remington 870 20 Gauge ASM220

This is a saddle type mount that is easily installed by pushing out the two receiver pins, putting the mount in place and securing with the two included threaded pins.
Shims are included for 20ga and are not used for 12ga.
Mount went on easily and is very secure. Dozens of hard turkey loads and my Red Dot sight has stayed on Zero.
Aimtech is a good solution if you don't want to permanently drill and tap your shotgun to accept a scope or other optics.
Pros: Easy to install and sturdy
Cons: Raises optics height slightly
