CMMG 55CA67D Pistol Tube Assembly Black w/ Ambi Sling End Plate - AR-15

The CMMG 55CA67D Pistol Tube Assembly is a complete replacement kit designed for AR-platform pistol builds. This assembly includes the basics needed to convert a standard adjustable-position carbine buffer tube into a fixed, smooth-sided pistol tube, giving AR pistols a clean, snag-free rear profile.

Machined from aluminum and finished in a durable matte black hard-coat anodized finish, the tube measures 1.253" in diameter and 7.28" in length, matching mil-spec pistol buffer tube dimensions. The included ambidextrous sling mount end plate provides a secure attachment point for slings on either side of the receiver, making sling attachment and adjustment quick and easy for both right- and left-handed shooters.

Designed specifically for the AR-15 platform, this assembly is a direct-fit replacement that requires no modifications to the lower receiver. The package includes:

• Pistol Buffer Tube
• Ambi Sling Mount / Receiver End Plate

Whether you are building a new AR pistol or upgrading an existing one, the CMMG 55CA67D Pistol Tube Assembly delivers a streamlined appearance and reliable performance backed by CMMG quality.
