Compact, tough and built for CQB performance, the G&G MGCR 556 GBB 12" brings a full‑feature gas blowback AR platform into a short, maneuverable package. Its aluminum M‑LOK 12" handguard and metal‑alloy receivers give the rifle a premium feel while keeping weight balanced for dynamic close‑quarters play.
Designed around real‑world ergonomics, this MGCR model includes flip‑up iron sights, an oversized ambidextrous mag and bolt release, plus a 6‑position retractable stock for fast adjustments in tight lanes. The low‑cap 30‑round gas magazine and an adjustable hop‑up let you tune performance for indoor fields or short‑range outdoor skirmishes. Power and blowback are provided by green gas — it’s a true gas blowback (GBB) setup for realistic cycling and recoil feel.
Internals are built for consistency: a precision CNC barrel assembly and double Teflon O‑ring nozzle help the MGCR deliver repeatable velocities and reliable sealing under rapid fire. The full‑steel trigger and reinforced buffer components improve longevity under regular play, while the M‑LOK handguard keeps accessory options open without adding bulk.
Whether you’re upgrading to a high‑end GBB platform or want a compact specialist rifle for CQB events, the MGCR 556 12" is tuned for quick target transitions, solid ergonomics and the familiar handling of an AR‑style system.
