  • unique serial number
  • Full metal body
  • CNC Free-Float Aluminum 22mm RAS Railsystem
  • TangoDown front handle and rail covers
  • built-in MosFet
  • Aluminum flip-up Battle Sights

The Tango Down ECR-5 AEG from Evolution AirSoft , manufactured by King Arms , delivers 330 fps / 1.0 joules out of the box. The Toprail is a 22 mm rail which allows mounting for many optics.

It is also practical that the Tango Down AEG series is completely compatible with Tokyo Marui M4 replicas . All magazines or tuning parts can therefore be used.

The Evolution Tango Down ECR-5 AEG comes with a mid-cap 130 BB polymer magazine, Tango front handle and Tango rail covers.

PLEASE NOTE: The use of an 11.1v or higher battery will void any warranty unless it is specified as our recommended battery for that particular AEG. Most quality airsoft guns do not come supplied with a battery or a charger.  On the rare occasion that they do have them included this is specifically mentioned in the product listing.   If they are included they are considered free gifts supplied by the manufacturer and cannot be returned if faulty. We recommend that when purchasing an airsoft gun you also purchase a new quality battery and charger for maximum reliability.
