Daniel Defense DDM4 MK18 RIII 12.5 Lightning Series gas-powered replica - Brown [EMG]

Designed with a focus on realistic handling, dynamic operation, and top-tier craftsmanship, it combines a durable aluminum construction, a precisely engineered gas system, and an official Daniel Defense license. Thanks to the Gas Blow Back (GBB) system, the replica delivers realistic recoil and bolt movement, offering an experience close to handling a real firearm. It's an excellent choice for milsim enthusiasts and tactical training.

Realistic replica under Daniel Defense license

The DD MK18 RIII 12.5 model is a licensed replica created in cooperation with EMG and Daniel Defense. The lower receiver features original, deeply engraved Daniel Defense markings, emphasizing the authenticity of the replica. The modern M-LOCK handguard allows the installation of various accessories - such as flashlights, lasers, grips, or red dot sights - offering extensive customization options in both appearance and functionality.

The replica also includes a licensed pistol grip with an aggressive texture and a Daniel Defense adjustable stock, ensuring a secure hold, comfort, and stability in any shooting position.

Premium-class construction - lightweight, durable, precise

The build combines steel critical components (trigger group, hammer, sear, bolt catch, pins) with aluminum parts (receiver set, buffer tube, outer barrel).
This combination provides high durability while maintaining low weight and precise operation.

The Lightning Series version features a lighter aluminum bolt and an optimized buffer, improving responsiveness, cycle rate, and rate of fire (up to 18 RPS). The replica is equipped with an ambidextrous charging handle and a quick hop-up chamber removal system, making maintenance and adjustment during games easier.

CYMA CGS Gas System - a new definition of realism

At the heart of the replica lies the advanced CYMA CGS (CYMA Gas System), developed in cooperation with T8 (SP System) and inspired by the renowned MWS M4/AR-15 platform.
The system ensures stable gas efficiency, precise bolt cycling, and strong recoil, resulting in the highest level of realism during use.

With its adjustable trigger, the user can fine-tune the feel to personal preference, while compatibility with AR-15 accessories allows for extensive customization.
