Upper and Lower Receiver
The upper receiver is made from anodized aluminum forgings, and is non-stressed. It features a non-reciprocating charging handle on left side which also acts as a forward assist.
The quad rail system is integrated into the upper receiver and compatible with most 1913 Picatinny devices. The top rail is monolithic and 17” long, providing a rigid, uninterrupted plane for mounting optics and BUIS (Backup Iron Sights); the 3, 6, and 9 O'clock Position Rails are 8" long.
