The assembly is retained within the upper receiver with an improved spiral design pin as opposed to a slotted version for increased strength and durability. Pins are fully certified by the manufacturer.
The design of the Cap has been improved by reducing its diameter and snagging potential, creating a more streamline surface flow when assembled into the upper receiver.
Exterior surface knurling around the caps edge allows for positive engagement with a gloved or naked hand while removing the circular ridge that exists on the current design.
