SA M4 CQB M-LOK Rifle (SA-E23 EDGE™ 2) - Black

Specna Arms SA-E23 EDGE™ HAL² Gen.2

Looking for a reliable and upgraded M4 airsoft rifle with a full metal body? Want an AEG that comes ready to perform with advanced internals and the HAL² ETU electronic unit? Need a complete set with a matching 11.1V battery and charger so you can jump straight into action? Then the M4 EDGE™ 2 is your best choice. This Gen.2 EDGE™ series from Specna Arms focuses on durability and detail — featuring a metal receiver with engraved Specna Arms markings. The M4 CQB M-LOK (SA-E23 EDGE™ 2) replica uses the Æther gearbox rated for M140 springs. Inside, you’ll find steel 16:1 gears on 8 mm bearings for a perfect balance of rate of fire and durability. The polycarbonate piston with 14 steel teeth ensures ideal AoE and prevents jams. Air compression is provided by a CNC aluminum nozzle mounted on a reinforced tappet plate. The HAL² ETU unit uses magnetic sensors and the Hall effect, offering active brake, binary trigger, adjustable sensitivity, pre-cocking, programmable firing modes, and a low battery alert. The latest version allows configuration through the Specna Link™ mobile app for iOS and Android. Precision is ensured by a 6.03 mm barrel and Helium™ Flat-Hop bucking inside a redesigned MAGNUS™ TDC hop-up chamber. Spring changes take seconds thanks to the ESA™ quick-change system. The set includes a Specna Arms 11.1V 1000 mAh Li-Po battery (20C) and EASY LIPO CHARGER.

• When using a progressive spring, ensure the tighter coil faces outward from the gearbox.
• Never store the rifle with a connected battery.
• Never store the rifle with pre-cocking engaged – always release the piston to prevent damage.
