Overview
The IWI Zion-15 11.5" SBR (model Z15TAC11-SBR) is IWI US's M4-pattern short-barreled rifle, built and assembled at the company's US facility. It runs an 11.5-inch 4150 chrome moly vanadium heavy barrel with 5R rifling, a 1:8 twist, and a nitride finish, threaded 1/2x28.
A 10.5-inch free-float M-LOK rail covers the barrel, and the rifle ships with a B5 Systems adjustable stock and grip and one 30-round Magpul PMAG. It measures 27 inches collapsed and 31.75 inches extended and weighs 6.5 lbs. As a factory SBR, it transfers stocked rather than as a braced pistol.
