Product Description

Designed to exceed the newest requirements of the US Army for improving zero retention/repeatability. With a new slimmer profile, CAA's newest Picatinny quad rail improves durability, reliability, and maintainability while interfacing with all issued weapon system components. The X4MS achieves superior zero retention and repeatability, by having the upper three rail section mount underneath the end cap and secured in place with a friction fit ledge and roll pins. The receiver end of the X4MS is secured to the barrel with a barrel nut bracket that is attached to the upper three rail section with four captive flathead screws. The bottom rail uses locking lugs with a retaining pin to keep it securely mounted to the upper handguard.

 

Four full-length rails

Top rail creates one long monolithic rail with the existing flat top rail

X4MS has two push-button sling swivel mounting points at the front

X4MSD has four push button sling mounting points at the front and back.

Slots around the rails provide maximum ventilation around the rails.

CNC machined from aviation grade aluminum to MIL-1913 standards with a hard anodized black oxide finish for durability and ease of maintenance.
