Steel pivot pin.
By tightening the screw (T8 Torx), the central inclined part protrudes, eliminating play between the upper and lower receivers.
This prevents the pin from loosening.
---------------------------------------------------------------------------------------------- 
The total length is approximately 38 mm when the pin is inserted, the screw is tightened, and the locking mechanism is in place.
The pin diameter is Φ6mm. 
The thickness of the pin head is about 4mm. Will it protrude too much when attached to the receiver?
Please confirm.
