SA Daniel Defense® MK18 Rifle (SA-E19 EDGE™ 2) - Chaos Bronze

Specna Arms Daniel Defense® MK18 (SA-E19) EDGE™ HAL² Gen.2

Looking for a premium MK18 replica with a solid metal body? Want your rifle to feature a state-of-the-art internal setup with the HAL² ETU processor unit? Need a ready-to-use set with the right battery and charger included? Then the MK18 EDGE™ 2 rifle from Specna Arms is your perfect choice. The EDGE™ Gen.2 series offers excellent metal body construction with official Daniel Defense® trademarks. The Daniel Defense® MK18 (SA-E19 EDGE™ 2) replica features the Æther gearbox, capable of handling M140 springs. Inside are steel 16:1 gears running on 8 mm bearings – a perfect balance between high RoF and durability. The reinforced polycarbonate piston with 14 teeth ensures ideal AoE (Angle of Engagement) and prevents jamming. The CNC aluminum nozzle on a reinforced tappet plate guarantees airtightness and reliability. The improved HAL² ETU system uses magnetic sensors and Hall effect detection, offering active brake, binary trigger, trigger sensitivity adjustment, pre-cocking, programmable fire modes, and low battery alert. The new version also allows configuration via the Specna Link™ app (iOS and Android). The 6.03 mm inner barrel and Helium™ Flat-Hop bucking inside the MAGNUS™ TDC hop-up chamber ensure excellent accuracy. The ESA™ quick-change system allows fast spring swaps. The set includes a Specna Arms 11.1V Li-Po battery (1000 mAh, 20C) and a Specna Arms EASY LIPO CHARGER.

Warnings

• Some manufacturers’ springs are overrated (e.g. M130 performs like M140–150). Use only Specna Arms springs. For other brands, use up to M120 to avoid damage.
• When replacing a progressive spring, ensure the tighter coil end faces outward from the gearbox.
• Never store the rifle with a connected battery.
• Never store with pre-cocking engaged — always release the piston to prevent spring fatigue.
