Description
Big-bore AR-10s have a reputation for being heavy, clunky, and hit or miss on accuracy, and the Zion-25 is IWI's answer to all three complaints. This is the shortest large-frame gas gun in the IWI US lineup, and it carries the same no-nonsense duty-grade DNA that made the Zion-15 a favorite, just scaled up to .308 Winchester. The heart of the rifle is a 4150 chrome moly vanadium heavy-profile barrel with a nitride treatment for durability and a 1:10 twist that stabilizes match ammo the way a .308 should. Muzzle threading comes in the standard 5/8×24 pattern, so your brake, comp, or suppressor mount goes right on.
What Sets the Zion-25 Apart
The trigger alone separates this rifle from most of the large-frame field. IWI ships every Zion-25 with a custom Timney two-stage unit, the same trigger that earned praise when it debuted on the Z-15 SPR, and it makes a real difference when you're squeezing off precise shots at distance. The 15-inch free-float Assaulter handguard gives you M-LOK slots all around plus a quarter ARCA rail section built in, which is a nice touch if you run a tripod for positional work or long sessions behind glass. An intermediate-length gas system with adjustable gas keeps the recoil impulse smoother than you'd expect from a .308 carbine, especially if you shoot suppressed.
Handling and Ergonomics on the Z-25
B5 Systems handles the furniture, with an 8-position adjustable stock and matching grip that fit a wide range of builds and body types, plus QD sling compatibility right out of the box. At 8 pounds 14.5 ounces with an overall length that collapses to 33.75 inches, this rifle stays manageable whether you're working a truck gun role, hog control, or just stretching its legs at the range. It ships with one 20-round Magpul PMAG LR/SR, the flattop upper is ready for the optic of your choice, and the whole thing is built and assembled at the IWI US facility here in the States.

Frequently Asked Questions
Does the IWI Zion-25 come with sights or an optic?
No, this rifle ships optic-ready with a bare flattop rail and no iron sights. That's typical for a large-frame gas gun in this class, since most owners mount an LPVO or magnified optic to take advantage of what the .308 cartridge can do. The full-length top rail gives you plenty of real estate for whatever setup you prefer.
Is the Zion-25 suppressor friendly?
Yes. The barrel is threaded in the standard 5/8×24 pattern common to .308 rifles, so most .30 caliber muzzle devices and suppressor mounts thread right on. The adjustable gas system is the real bonus here, since you can tune the gas down to keep the rifle running smoothly and reduce blowback when shooting suppressed.
What magazines does the IWI Zion-25 accept?
It uses SR-25 pattern magazines and ships with one 20-round Magpul PMAG LR/SR. That's the most common large-frame AR magazine pattern out there, so spares are affordable and easy to find in various capacities.
How accurate is the Zion-25 with match ammo?
IWI built this rifle with accuracy in mind. The free-floated 1:10 twist chrome moly vanadium heavy barrel is designed to get the most out of match-grade .308 loads, and the Timney two-stage trigger gives you the clean, predictable break you need to take advantage of it. Feed it quality ammo in the 168 to 175 grain range and it rewards good fundamentals.
