Arcturus SR16 CQB Ambi FE™ M-LOK - Black

SR16 CQB Ambi FE™ by Arcturus

The SR16 CQB Ambi FE™ by Arcturus is a premium airsoft rifle that combines modern technology with the classic AR-15 design in a fully ambidextrous configuration, making it perfect for both left- and right-handed users. It features a fire selector, bolt catch, and magazine release on both sides. With precision engineering and a rugged build, this rifle delivers top-tier performance straight out of the box. The receiver and CNC-machined handguard are made from aluminum with a hard anodized finish, ensuring exceptional durability and longevity. Simply put, it’s a solid piece of aluminum that outperforms standard alloy bodies.
Arcturus rifles are not just great externally; they also feature premium internal components. This rifle is equipped with a next-generation ARC FE (ETU) electronic trigger unit, allowing users to adjust firing modes (Semi, 3rd Burst, Binary, Full Auto), pre-cocking (pre-cocking) for instant trigger response, and active braking to prevent unwanted piston movement after firing. The ETU also features overvoltage protection and low-battery warnings.

Internal Components

The rifle features a reinforced V2 Hybrid gearbox with quick spring change (QSC), allowing users to adjust power levels for different airsoft events without disassembling the gearbox.
The gearbox is fitted with CNC-machined steel 18:1 gears and a powerful 24k neodymium 21TPA motor.
Hop-up is adjusted via the ARCTURUS RS™ rotary polymer chamber, providing precise control over BB trajectory. The inner barrel is a 6.03mm precision barrel measuring 270mm, making it ideal for CQB scenarios while still offering solid performance at mid-range distances.

External Build

The rifle's body is made of aluminum, including the CNC-machined handguard, which is equipped with M-LOK slots and a top RIS rail. The upper receiver also includes a full-length RIS rail for mounting optics.
The Mil-Spec buffer tube supports a polymer AR15 collapsible stock, providing ample space for a Buffer Stick battery. The package also includes a flash hider, which can be easily swapped thanks to the 14mm CCW left-hand thread.
