This Dueck Defense-style RBU (Red Dot Back Up Sight Base) is for the RMR red dot sight. It's a replica of the red dot backup sight base for Glock guns, developed by Dueck Defense, a firearms accessory manufacturer founded by former Marine and renowned shooter/developer Barry Dueck.
By combining the red dot sight mount base and backup sight into one, you can prevent losing sight of the red dot and enable quick and accurate aiming. In addition, when used in combination with a green insert, you can expect improved visibility of the red dot.
In addition, by providing a slight height to the base, the obstruction of the line of sight when a silencer is attached is minimized, allowing for shooting without sacrificing tactical aspects. This is a simple yet practical product, designed by a veteran with ample combat experience. Installation is as easy as replacing the rear sight, making it a recommended choice for those customizing their Glock.
