Specna Arms SA-F05 FLEX™ Gen.2 BLDC Airsoft Carbine — Full Dark Bronze

Specna Arms SA-F05 FLEX Gen.2 BLDC is an electric airsoft replica based on the M4 / AR15 / M16 platform, equipped with a programmable HAL™ ETU control unit and a Dark Matter™ High Speed 27–35k brushless motor.

The FLEX Gen.2 series combines a lightweight design, extensive adjustment options, and an affordable price. This model features a TDC Magnus™ Hop-Up chamber, reinforced Æther™ gearbox, and ESA™ quick spring change system.

External construction

The replica body and 10.5-inch M-LOK handguard are made of nylon. The pistol grip, buffer tube, adjustable stock with a rubber shoulder pad, and mechanical sights are also made of nylon.

Aluminum parts include the muzzle device, outer barrel, controls, and charging handle. The pins, screws, and QD sling mounts are made of steel.

The model features an ambidextrous fire selector, ambidextrous magazine release, and functional bolt catch.

The minimalist Light Ops Stock is adjustable. It has non-slip rubber panels on both sides of the cheek rest and a curved rubber shoulder pad for a comfortable fit.

Hop-Up and internal components

The rotary TDC Magnus™ Hop-Up chamber allows precise and consistent adjustment of BB backspin. The chamber’s design is protected by European Registered Community Design No. 015052069-0001.

The chamber works with the Helium™ Flat Hop bucking, designed to provide consistent BB backspin. The replica is also fitted with an aluminum air nozzle with an O-ring and a 6.03 mm inner barrel.

Internal components:

• 8 mm bushings

• Steel gears

• Polycarbonate piston with a full steel tooth rack

• Dark Matter™ High Speed 27–35k brushless motor

Æther™ gearbox and ESA™ system

The replica is fitted with a reinforced Æther™ gearbox shell, whose design is protected by European Registered Community Design No. 015044865-0001.

Gearbox shell features:

• Main spring tension release function

• Inspection ports for checking pre-cocking and the piston engagement angle (AoE)

• Reinforced front section

• Inspection ports to facilitate gear shimming

• Trigger adjustment option

• Screw holes for precise alignment of the shell halves

• Designed for springs up to M140

The ESA™ quick spring change system lets you adjust the replica’s muzzle energy to suit the requirements of the game without disassembling the entire gearbox.
