Assault Rifle M4

Who doesn’t know the legendary assault rifle MK 18? It has appeared in countless movies, TV series, and most of us have chosen it as our primary weapon in games from Call of Duty to Escape from Tarkov. Above all, it is a time-tested tool used by various special forces worldwide,
including the Czech 601st Special Forces Group.
The MK18 rifle has its roots in a modified version of the M4 carbine, developed to meet the needs of special units. The first version of MK18 was created based on the requirements of the U.S. Navy SEALs for a compact and highly efficient rifle for close combat.
A key feature of the classic MK18 is the shortened barrel measuring 10.3 inches, which allows for easier handling in tight spaces and quicker deployment in close-quarters operations.
The airsoft AEG assault rifle of the One™ series by Specna Arms emphasizes top-quality metal body workmanship and premium CNC metal internal parts.
Compared to the Edge series, it differs in that it does not include a mosfet (or processor unit in Edge 2.0), the piston has only 1 metal tooth, and the spring change system is different (more time-consuming).

What does Specna Arms MK18 (SA-A03 ONE™) offer?

Internal Parts

The replica MK18 (SA-A03 ONE™) is equipped with classic mechanical trigger contacts, thus allowing safe use only with Li-Pol batteries 7.4V or you can use standard NiMh cells.
The gun is equipped with an adjustable Hop-up chamber with a quality rubber for excellent range.
It also features the increasingly common standard of today’s times, the QSC quick spring change system Enter&Covert, which allows you to install a stronger/weaker spring according to your discretion. The spring can be replaced only after removing the gearbox from the gun body (basic knowledge of disassembling the external parts of an AEG weapon such as the stock, grip, etc. is necessary).
The gearbox is reinforced and includes premium internal parts (the list of which is provided below in the description). The manufacturer states the gearbox’s durability up to a spring of M120 strength.

Overall, it is a rifle that combines top performance with an attractive design for maximum player satisfaction.
