Confidence out of the case.

Why Choose the Assurance-UTE?

• Ready on Day One: A2 front/rear sights mean you can confirm zero and start training right away; optics can be added when you’re ready.

• Stainless Accuracy, Carbine Handling: The 16" stainless barrel balances corrosion resistance with consistent groups and quick, maneuverable handling.

• Battle-Proven Caliber: Chambered for 5.56 NATO (also runs .223 Rem with proper ammo), giving you broad ammunition availability from practice to defensive loads.

• RRA Ergonomics: The Operator Stock provides a stable cheek weld and adjustable length of pull; the Hogue® grip delivers secure traction in rain, sweat, or gloves.

• Rock River Reliability: Tight receiver fit and quality assembly support dependable cycling with common 55–77gr loads.

Note: Handguard style, muzzle device, and trigger configuration can vary by production lot or distributor. Confirm current specifications with your retailer.
