Arcturus SR16 Rifle Ambi FE™ M-LOK - Black

SR16 Rifle Ambi FE™ by Arcturus

The SR16 Rifle Ambi FE™ from Arcturus is a top-tier airsoft rifle that combines modern technology with a classic AR-15 design in a fully ambidextrous (Ambi) configuration for both left- and right-handed shooters. This includes a fire selector switch, bolt catch, and magazine release. With precise craftsmanship and a robust construction, it offers excellent out-of-the-box performance. The body is made of cast aluminum, and the handguard features a hard anodized finish for increased durability and longevity.
Arcturus rifles are not only outstanding on the outside but also on the inside. The rifle is equipped with the ARC FE electronic unit (ETU), which enables fire mode customization (Semi, 3rd Burst, Binary, Full Auto), pre-cocking for an ultra-fast trigger response, and an active brake that prevents unwanted piston movement after a shot. The electronics also include overvoltage protection and a low-battery warning.

Internal Parts

Inside, you will find a reinforced V2 Hybrid gearbox with quick spring change (QSC), allowing for easy performance adjustments to match different game scenarios.
The gearbox features CNC-machined steel gears in an 18:1 ratio and a 24k high-torque 21TPA neodymium motor.
The hop-up is managed by an ARCTURUS RS™ rotary polymer chamber, which ensures precise BB trajectory adjustment. The 6.03mm precision inner barrel is 450mm long, making it ideal for long-range shooting.

External Build

The rifle’s body is made from aluminum, including the CNC-machined handguard equipped with M-LOK slots and a top RIS rail. The upper receiver also features a RIS rail for mounting optics.
The aluminum Mil-Spec buffer tube and polymer AR15-style adjustable stock provide ample space for buffer stick batteries. Included in the package is a flash hider, which can be easily replaced thanks to the standard 14-mm CCW left-hand thread.
