The Geissele Automatics 05313S, also known as the Super Charging Handle (SCH), is intricately crafted from a substantial block of 7075-T6 grade, aircraft quality aluminum. Upholding consistency in its strength and durability, it is complete with a hardcoat anodized finish. An unmistakable feature is its ambidextrous design that promotes a smooth, uninterrupted operation regardless of which side of the weapon you are on.
