SILVER SHADOW GILBOA G16556SAB | 5.56 NATO | 16″

The Silver Shadow / Gilboa G16556SAB is a 16-inch carbine chambered for .223 Rem / 5.56x45mm that combines a 416 stainless barrel with a nitride-finished bolt carrier group and adjustable synthetic stock for practical, service-oriented handling. Construction details include a billet upper, forged lower, free-float M-LOK handguard, and a black finish throughout. For a capable optic under $1,000 that pairs well with this carbine, consider a Vortex Strike Eagle 1-6×24 — it balances speed and precision for typical carbine work.

Typical use cases for this rifle include competition or matches that favor compact carbines and professional/patrol-style field use where reliable, modular performance is required.
