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.\u003c\/p\u003e\u003cp\u003eAll of Daniel Defense’s Barrels offer high performance and a long lasting construction.
