Fully licensed by Knight's Armament Airsoft

This AEG is fully licensed by Knight's Armament Airsoft and made in collaboration with Z-Shot Inc. and Echo1 USA. That means you get the Echo1 USA 30day warranty and product support as well as the legendary Knight's Armament markings on the airsoft gun. These guns will take a lot of punishment and keep on working.

URX4 Keymod Rail System

The SR-16E3 features the Knight's URX4 Keymod rail system. Keymod rail systems are modular handguards that allow placement of accessories with simple tools in seconds. You can add rail sections or Keymod specific accessories that will mount directly to the rail system for an even more streamlined look.

Keymod Rails and Accessories

The SR-16E3 comes with extra accessories for added better value. Included are two 5-slot keymod rail sections and one 10-slot keymod rail section which will allow you to mount accessories like lights and lasers right out of the box. Also included are micro backup sights which are very low profile and do not interfere with other accessories.


Echo1 Mk1 Flash Hider

The orange Mk1 flash hider that comes equipped with the SR-16E3 is directly compatible with the Echo1 Mk1 SR556 barrel extension (SOLD SEPARATELY) so you can add the mock suppressor look without voiding your warranty from removing the orange tip.


Reinforced Nylon Fiber Body

The body is made of a tougher nylon fiber reinforced polymer that is stronger than anything used previously by Echo1. It allows for quicker takedown and utilizes a 1-piece hopup chamber.
