SHOTGUN MOUNT BASE《MB-5L》for CA870, M870 & M1100 SERIES
Long aluminum mount base for shotguns that can be attached to Maruzen CA870, M870 & M1100 series.
This mount base can also be used with the CA870, M870 series, and M1100 series. It features a 20mm wide, approximately 350mm long rail on the top, allowing you to attach various compatible 20mm wide mounts (such as red dot sights and scopes).
The mount base itself is made from a lightweight, one-piece, machined aluminum. It can be attached to each shotgun's receiver without any processing. The dedicated steel receiver pin and screws required for installation are also included.
★The long rail extending above the outer barrel gives it a new look, dressing it up into a unique tactical shotgun.
Important Note: This product is primarily intended for customizing and dressing up your gun's appearance. The mount base is made of a one-piece aluminum construction, and since the front of the rail is not connected to the gun body after installation, it is not very rigid. Therefore, we do not recommend attaching heavy mounts to the front of the rail or holding the front of the rail with your hand, or using it in a way that applies excessive force. Please be sure to understand these characteristics before purchasing and using this product.
*Although the MB-5L mount base is 20mm wide, we cannot guarantee that all commercially available mounts (such as red dot sights) will fit securely. Please also note that when attaching a mount, it may leave marks or scratches on the mount rail.
*For the CA870 equipped with an adjustable hop-up function, insert a hex wrench into the "adjustable hop-up adjustment hole" on the top of the mount base to adjust the hop-up.
