Our 6-32 threaded roll pin is used in multiple applications, including for the bolt catch on our RO21 and A-10 Lower Receivers and for the forward assist on our Upper Receivers. Made from stainless steel, it has a 6-32 thread pitch and is designed to be installed with a 1/16″ Hex Key Wrench.
Note: This product is already included with our RO21 and A-10 Uppers & Lower Receivers.. It is not necessary to be purchased separately. This individual product is available for customers who have lost or damaged their existing threaded roll pin.
