Daniel Defense 5.56mm NATO 18" 1:7" CMV CHF Rifle-Length S2W Barrel Assembly 07-116-05042-018

For the Daniel Defense 5.56 NATO 18" 1:7 CMV Rifle‑Length S2W Barrel Assembly the only exact factory spec you can count on is the barrel length: 18" (457.2 mm); height and width aren’t published as single standardized figures because they depend on contour, gas block style, and any muzzle device. As a practical estimate, expect a maximum width (outside diameter) in the range of 0.75–1.10" (19–28 mm) and a height from the bottom of the barrel to the tallest feature (gas block or sight) of roughly 1.25–2.00" (32–51 mm) — but the installed muzzle device or low/high gas block can shift those numbers. For exact, CAD‑ready dimensions, download the Daniel Defense product spec sheet or contour drawing for part #07‑116‑05042‑018 from the manufacturer’s site or contact their customer service; they can provide official drawings or precise max‑diameter and profile measurements.
