Andro Corp Industries U556103ML Complete Upper 5.56 NATO 10.3" M-LOK

The Andro Corp Industries U556103ML is a complete AR-15 upper receiver kit chambered in 5.56 NATO, built around a 10.3" barrel. The 10.3" barrel length pairs with a carbine-length gas system optimized for short-barreled configurations. The upper features a free-float M-LOK handguard, providing a lightweight and modular platform for accessory attachment. The muzzle is threaded for suppressor or muzzle device installation. This upper is well-suited for SBR builds and close-quarters applications requiring a compact yet capable direct impingement configuration.
