The Zion-15 is the first M4-style rifle from IWI US. The Zion-15 features a standard tactical-style setup with a free-float M-LOK handguard that allows for ample space for various accessories and optics while allowing for faster air cooling and a reduced handguard profile. The barrel has been cut to a heavy profile that allows for better heat resistance and lower muzzle climb.

Included with the rifle is the SOPMOD Enhanced stock and pistol grip developed by B5 Systems. The B5 SOPMOD Enhanced stock is a modernized reproduction of famous SOPMOD stock used by special operations in the early 2000s and features two storage compartments in the buttstock for batteries and tools as well as a sloped ergonomic design that allows for a far more comfortable cheek rest. The addition of an anti-rotation QD socket in the stock allows for quick attachment of slings while preventing the slings from binding.

This model is chambered in 5.56x45mm NATO and features an all-black finish. One 10-round Magpul Industries PMAG magazine is included.
