About this product
The IWI Zion-15 is a domestically built, AR-15-pattern pistol chambered in 5.56 NATO / .223 Remington, built by IWI US to the same military-grade quality-control standards the company applies to its rifles. It runs a 12.5-inch chrome-lined, cold-hammer-forged barrel with a 1:7 twist and a mid-length gas system, topped with a free-float M-LOK handguard, and ships with an SB Tactical brace already installed. It's an AR platform pistol, not a rifle — no shoulder stock, shorter overall length, and a different set of federal and state rules apply.
What is it used for?
It's a short, maneuverable 5.56 platform for home defense, truck-gun duty, or range use where a full-length rifle is more than you want to handle. The mid-length gas system and chrome-lined bore are built to run reliably on both 5.56 NATO and .223 Remington ammunition without the harsher cycling some shorter-barrel, shorter-gas-system pistols show.
How does it compare to a full-length AR-15 rifle?
The 12.5-inch barrel and pistol brace make it dramatically shorter and easier to store or maneuver in tight spaces than a 16-inch-barrel rifle, at the cost of reduced velocity and slightly more muzzle blast from the shorter barrel. It also sidesteps the rifle-length overall-length rules that apply to short-barreled rifles, provided it stays configured and used as a pistol.
What fits it?
It uses the M-LOK slots on the free-float handguard for lights, foregrips, and slings, and it accepts standard AR-15 magazines — 30-round in unrestricted states, 10-round in states that cap rifle-type magazine capacity. The SB Tactical brace it ships with can be swapped for other AR-pattern braces or, depending on your state and current federal rules, other stabilizing devices.
Who is this not for?
If you want a lightweight truck gun, note the forged receivers and chrome-lined barrel add real weight — around 6.5 pounds — compared to some lighter AR pistols. It's also not the gun to buy without first understanding your state's rules on braced pistols and featureless configurations; those rules have shifted at the federal level and vary by state, so confirm current requirements before you build a plan around one.
Does it work in California?
It ships to your FFL dealer only, like every firearm we sell, and configuration for California delivery — featureless or fixed-magazine, per current state law — has to be arranged with your dealer before transfer. Braced pistols are also subject to current federal rules that have changed more than once in recent years, so confirm both state and federal requirements with your dealer before you order. See our California gun laws page for the current overview.

Frequently asked questions
- Does it come with a stock or a brace?
- It ships with an SB Tactical brace, not a shoulder stock. As sold, it is legally a pistol, not a rifle.
- What magazine capacity ships with it?
- A 30-round magazine ships with the standard configuration; a 10-round magazine ships instead for customers in restricted-capacity states.
- Is 5.56 NATO the same as .223 Remington in this gun?
- The barrel is chambered to safely fire both 5.56 NATO and .223 Remington, which is standard for a 5.56-marked chamber, but 5.56 should not be fired from a barrel marked .223-only.
- How much does it weigh?
- Approximately 6.5 pounds unloaded, which is on the heavier side for an AR pistol due to the forged receivers and chrome-lined barrel.
- Can I add a stock to it later?
- Converting a pistol-braced AR to a shouldered, stocked configuration changes its legal classification and may require an ATF Form 1 or other paperwork depending on current federal rules — talk to us before modifying it.
