M4 is a compact automatic rifle developed in the United States based on the popular M16 assault rifle. It was designed to meet the need for a lighter and shorter version of the M16 suitable for use in confined spaces and urban combat.
In the 1960s, the M16, developed by Armalite and adopted by the US Army, served as the basic design for the M4. In the 1980s, the first prototypes of the M4 appeared with a shorter barrel and a telescopic stock, improving maneuverability in confined spaces.
In the 1990s, the M4 was officially adopted by the US Armed Forces as the standard carbine, replacing older models like the M3 and M9. The rifle features the ability to fire both single shots and bursts, making it a versatile weapon.
The M4 quickly became popular among soldiers due to its light weight, compactness, and reliability. It was widely used in conflicts such as the Iraq and Afghanistan wars and became an iconic weapon of modern US armed forces.
In addition to the standard model, there are many variants of the M4 equipped with various accessories and enhancements to meet the specific needs of military units.
The airsoft AEG assault rifle M4 in the basic series FLEX™ by Specna Arms emphasizes lightweight nylon body while also offering top-notch construction and fit. The body is reinforced with fiberglass and is more durable than the common zinc alloys found in cheap metal bodies, which will be appreciated by both beginners and advanced players who prefer fast-paced action in the style of speedsoft, where every gram counts. This type of body can also be found on weapons like the CZ Scorpion Evo and the MP7.
The FLEX series is essentially a sibling of the CORE series, which features CNC metal handguards, while this FLEX series has nylon handguards. The internal parts remain the same as those in the CORE, but the unit is controlled by a Gate X-ASR Mosfet, as in the EDGE (1.0) series.
Internal Parts
The replica M4 Keymod (SA-F02 FLEX™) is equipped with a MOSFET X-ASR module from the Polish company GATE. This module ensures safe switching and protects the internal parts, improves trigger response and extends battery life, increases the rate of fire, and allows safe use of Li-Pol batteries 7.4V and 11.1V. Thanks to the integrated status LEDs, the module can diagnose basic malfunctions in the weapon.
The weapon is equipped with a 6.03 mm precision barrel and an adjustable Hop-up chamber with a quality rubber for excellent range.
Additionally, the increasingly common QSC ESA quick spring change system allows you to install a stronger or weaker spring as you see fit. The spring can be replaced without removing the gearbox from the weapon's body, and the process is easily done through the stock tube.
The gearbox is also reinforced and capable of operating with springs up to M120, as stated by the manufacturer Specna Arms.
External Parts
The replica Specna Arms M4 Keymod (SA-F02 FLEX™) excels with its high-quality external finish of the nylon body, which has a matte appearance and feels very realistic. Reinforced with fiberglass, it is both very durable and lightweight.
The external barrel is made of metal, and the screws, ejection port, and pins are even made of steel. The ergonomic design of the AR15 rifles and their modern construction guarantee comfortable handling and easy control; this rifle simply fits in your hand!
Nylon Keymod handguard M4 allows for the attachment of various accessories such as grips, AN/PEQ boxes, flashlights, etc.
With an adjustable stock Crane type, this replica is ready for various game situations and allows the insertion of batteries (type Buffer Stick, Nunchuck, or Crane).
Overall, this rifle combines lightweight construction and great internal parts with an attractive price.
