GBBR Rifle UMAREX HK416 A5 Gen3 — Black

The UMAREX HK416 A5 GBBR, developed in collaboration with VFC, is a full metal airsoft replica of the HK416 A5 assault rifle in a gas blowback configuration. The outer barrel measures 368 mm, reproducing the proportions of the real-steel reference in every structural component.

The gas blowback system produces a noticeable recoil on each shot and cycles the bolt carrier through the same charge and discharge sequence as the original firearm. This means the bolt locks back on an empty magazine and the manual reload follows the same procedure as the real weapon — a practical advantage for anyone using this replica for procedural training or milsim where weapon handling is part of the game. The trade-off is well known: a GBBR consumes more gas than a non-blowback system, and performance can drop in cold temperatures; this should factor into your choice of magazines and gas type.

The full metal construction, with H&K roll marks on the receiver, is paired with fully ambidextrous controls: fire selector, bolt catch, and magazine release are all operable by both right- and left-handed users. The fixed metal handguard provides a stable platform for mounting accessories on all four rail sections. Firing modes include safe, semi-automatic, and full-auto.

Key features

• GBBR system with real recoil and bolt hold-open on empty: weapon manipulation accurately replicates the procedures of the original platform.
• Full metal construction with H&K markings on the receiver: the weight and tactile feedback match a real firearm, not a polymer replica.
• Fully ambidextrous controls on selector, bolt catch, and magazine release: no adaptations needed for left-handed operators.
• Fixed handguard with rails on four sides: allows mounting lights, lasers, and other accessories without structural play.
