SA 416D Carbine (SA-FH07 FLEX™ HAL ETU™) - Black

Assault Rifle HK416

HK416 is an assault rifle developed by the German company Heckler & Koch. The development of the weapon began in the 1990s with the goal of creating a rifle that would provide higher reliability and accuracy than the then-standard American M4. The result was the HK416, which combines several key innovations. In 2004, the HK416 was introduced to the public for the first time. The weapon quickly became popular due to its gas system derived from the HK G36, which ensured higher reliability.
In 2006, the first version of the HK416 was put into service, tested and used by special units worldwide. In 2007, the American special forces SEALs began using the HK416, further enhancing its reputation. In 2008, the HK416 became the main assault rifle of the French RAID unit and other special units. Throughout the 2010s, the HK416 was adopted by various armed forces and police units around the world.
HK416 is the standard model, offering a robust and reliable construction with interchangeable barrels of various lengths (10.4", 14.5", 16.5", 20"). This model is equipped with the standard gas system by Heckler & Koch.
HK416C is a compact version, designed with a shorter barrel and telescopic stock, making it ideal for operations in confined spaces such as vehicles or urban environments.
HK416A5 is a modernized version of the original HK416, introduced in 2012. Improvements include a redesigned gas system, better ergonomics, and greater modularity.
The current use of the HK416 and its variants is widespread, encompassing military and police units worldwide. The weapon is valued for its reliability, accuracy, and modularity, making it one of the most popular assault rifles today.
The AEG assault rifle HK416 in the basic FLEX™ series by Specna Arms emphasizes a lightweight nylon body combined with excellent construction and fit. The fiberglass-reinforced body offers greater durability than standard metal alloys, appreciated by beginners and advanced players alike who favor the lightweight nature for speedsoft action. This material is also found in the CZ Scorpion Evo and MP7.
The FLEX series is essentially a counterpart to the CORE series, with FLEX featuring a nylon handguard compared to the CNC metal handguard in CORE. Internal components are identical to CORE.
