The Fostech Stryker Echo Sport is a 16-inch AR-15 style semi-automatic rifle chambered in 5.56 NATO. It's built in the ECHOsport configuration with a Tomahawk stock, a Sabre Grip, and a 13-inch handguard, giving it a chassis-style look while keeping standard AR-15 ergonomics and controls. It runs on standard AR-15 magazines and is set up as an optic-ready platform out of the box.

Fostech's Stryker line generally gets credit from owners for running like a standard AR-15 platform, since it keeps the same operating system and most of the same parts compatibility. Feedback on the Echo Sport variant tends to center on the fit and finish of the aftermarket furniture rather than the core action.

The Tomahawk stock and Sabre Grip give the rifle a distinct look compared to a mil-spec AR-15, and shooters who like a more finished, chassis-style feel tend to appreciate it. The 13-inch handguard offers plenty of room for a foregrip or light, though shooters used to shorter handguards sometimes need to adjust their support-hand position.

Because it runs standard AR-15 magazines, owners aren't limited on magazine choice, and the rifle accepts the same broad range of AR-15 pattern optics and accessories. Buyers drawn to the Echo Sport configuration are usually looking for a rifle that looks different from a basic AR-15 without giving up parts compatibility.
