Cybergun FN Herstal M4A1 (BLACK)

The licenced FN Herstal M4 and M4A1 GBB Rifle, which was created in cooperation with Armorer Works, is produced by Cybergun and WE-Tech Airsoft. The Rifles use the M4 GBBR system.
FN Herstal America will start carrying out its commitments under a deal to provide the United States Army with M4 and M4A1 carbines in February 2020.
The weapon that is now employed as the standard issue service weapon by the American military serves as the design inspiration for the officially licenced Cybergun FN M4A1.
This gas airsoft rifle is an excellent option for players who want to build a more standard-issue-style gun because it has FN markings similar to those on many modern weapons used by the US military.

The rifle features a durable outside and is furnished with typical controls and extras, like a Picatinny rail. Additionally, a wide range of aftermarket parts that operate with WE standard components can use the dimensions.
The gun's internal gas system is similarly modelled after the AW Custom and the WE. As a result, your rifle will have a quick recoil and access to an extensive range of parts that will enable you to modify or customise it however you desire.


  • Fully licensed replica of the real FN M4A1 rifle
  • 1:1 scale with the real deal, including engraved trademarks
  • Durable full metal construction
  • Full gas blowback system for enhanced realism
  • Utilized the WE-Tech system for widespread parts availability and compatibility
  • Railed upper receiver for attaching optics and other accessories
  • Drop-in quad RIS allows for the addition of grips, lights, lasers, and other standard 20mm RIS accessories
  • Six-position adjustable stock on standard mil-spec buffer tube
  • Includes easy to use flip-up rear sight
