It's time to renew the Colt license with the new M4 Sierra! 

Part of a brand new range, this M4 is compact and accurate: ideal for CQB fields. 

Available in black, it has a short handguard and a PDW stock that can hold a very small 7.4 V LiPo battery

This AEG has a more reliable internal: 

• Piston with steel teeth for greater durability

• 8 mm bearings for smoother cycling 

• Quick spring change 

• Electronic board with Mosfet included and magnetic sensor replacing the cut off lever

And like any decent M4 model, it offers numerous accessory mounting options thanks to its many picatinny rails.

This replica is delivered with a 300 round hi-cap magazine and a short front grip.

• Official Colt markings for added realism;

• Reinforced internal parts for better performance;

• PDW stock with 6 settings for better compactness;

• Comes with a short front grip for better grip and stability;

• Increased durability, realism and quality thanks to its aluminum body;

• This replica is sold without a battery and a charger.

• !! ACHTUNG! Es ist wenig Platz für den Akku(wegen dem langen Anschlusskabel in der Waffe),
  etwas Fingerspitzengefühl ist notwenig oder eine Kürzung des Anschlusskabels.
