Seria CYMA CGS LS (Lightning Series) sets a new standard among GBB gas replicas. It combines realistic operation, a solid aluminum construction and compatibility with accessories based on the AR-15 platform. The applied CGS gas system (CYMA Gas System) offers sensations close to the operation of a real firearm - with noticeable recoil, a precise bolt cycle and stable feeding. Each model in the LS series has been designed for players who expect the highest level of realism without the need for modifications right out of the box. It is an ideal choice for milsim enthusiasts, tactical training and experienced ASG users.

Full license

Cyma and EMG, in cooperation with leading firearm manufacturers, proudly present a fully licensed replica of the EMG Daniel Defense DDM4 MK18 RIII 9.5 inches. This modern gas replica, based on the advanced CYMA CGS system, raises the bar for reliability. Thanks to precise design and rigorous testing, it delivers high quality and realistic sensations among gas replicas.

Features and AR-15 Ergonomics

The precisely reproduced MK18 silhouette is a licensed interpretation of Daniel Defense designs — the receiver bears deep, engraved markings that amplify the authentic appearance. In addition the Lancer Systems magazine faithfully imitates the L5 AWM magazine, including the "5.56x45" markings, which further reinforces the set's realistic character.

The EMG Daniel Defense DDM4 PDW airsoft carbine offers proven solutions for close- and mid-range engagements. Its 10.5-inch barrel performs excellently in these applications. Thanks to the Daniel Defense license, the model is equipped with an MFR RII handguard with an upper RIS rail and an M-LOK system allowing accessory mounting; the entire upper part of the replica features a Picatinny rail, enabling installation of various types of devices, including optics.

Daniel Defense also licensed a pistol grip with aggressive texture, which improves handling of the carbine and provides a more secure grip. For user convenience the replica has a Daniel Defense licensed adjustable stock, which allows adjustment of the weapon's balance and settings to the preferred shooting position. Such a well-thought-out design enables players to maintain high performance and mobility during prolonged matches.

Reliable internal system Lightning Series CYMA CGS (CYMA Gas System)

The gas replica EMG Daniel Defense MK18 combines modern construction solutions with top-class materials — its heart is the innovative CYMA CGS system, developed in cooperation with T8 (SP System) and modeled on the well-known MWS M4/AR-15 series. This mechanism provides high reliability and precision of operation, forming a solid base for further modifications. The introduction of an adjustable trigger gives the user better control and the possibility to adjust the shot characteristics, and the wide range of available upgrades allows further personalization of the replica.

To reduce weight and improve operating dynamics — including rate of fire (RPS) up to 18 — an aluminium bolt and an optimized polymer buffer are used (the Lightning Series version is characterized by an even lighter bolt and an improved buffer, which increases responsiveness). Critical mechanical elements are made of steel — e.g., the complete trigger group, hammer, sear, bolt release, magazine catch, pins — which ensures durability under intensive use. Meanwhile parts such as the trigger housing, bolt carrier, stock rails and the outer barrel are made of aluminium, keeping them light yet durable.

The replica features an ambidextrous charging handle, quick-release hop-up chamber that facilitates maintenance. The model combines lightness, solidity and high operational efficiency
