The Spare Hardware Kit for the Magpul AFG & MBUS is a US-made installation hardware replacement pack designed for use with the Magpul polymer MBUS Sights (MAG247 & MAG248), AFG (MAG411) and AFG-2 (MAG414) Angled Fore Grips, and the Rail Light Mount (MAG498).

The mounting screw features a dual drive head which gives the user the option to use either a 1/8” hex key or flat edge screwdriver for installation. A machined shoulder on the screws serves as an over-torque stop, which helps mitigate damage to the accessory and the rail platform it is being installed on. A reusable anti-vibration patch applied to the threads helps prevent loosening.

Included in the hardware kit is an installation hex nut and a front sight elevation adjustment tool which is compatible with the MBUS Front Sight.
