[UMAREX/GHK] HK416A5 11-inch CO2 GBBR Gas Blowback Rifle, Cerakote Spec, Japan Premium Ver. [V3AR System 2025 Edition/Officially Licensed] (New October 2025)

The HK416A5 is an improved version of the HK416 series assault rifle, developed by the German company Heckler & Koch. It chambers 5.56x45mm NATO ammunition and employs a short-stroke gas piston. It boasts high reliability, easy maintenance, and consistent performance even in harsh environments. The A5 model features a tool-less two-stage gas regulator for suppressor operation, an ambidextrous selector, a large charging handle for improved operability, and a durable cold-forged barrel. Additionally, the latest model, the A8, features a lightweight M-LOK handguard, an improved trigger, and further weight reduction. It has been adopted by the German Bundeswehr as the "G95A1." It has also been adopted by the French military as the HK416F, and the U.S. Marine Corps operates it under the designation M27 IAR. Its excellent durability, accuracy, and modularity make it one of the most reliable modern standard-issue rifles, widely used by military and law enforcement agencies worldwide.

Officially licensed and manufactured by Taiwanese toy gun manufacturer GHK, the HK416A5 stands out for its meticulous reproduction of every detail, from the exterior appearance to the detailed engravings and shape of each part. The 2025 V3 specification follows GHK's powerful AR system internally, but adds design changes such as a detachable bolt weight and a recoil buffer with a counterweight, making it a third-generation (V3) AR system.
It is produced under license, and not only is the size and texture realistic, but even the engravings on each part are reproduced.
Furthermore, some of the exterior parts are manufactured using processes that conform to those of real guns, making this a gun that is packed with a variety of attention to detail.
*Due to the licensor's instructions and manufacturing constraints, there are some parts that cannot be perfectly reproduced.
*While the V3 system provides intense recoil and fast cycles, the individual parts wear out quickly and require regular maintenance and part replacement.

GHK Japan provides support for any problems or malfunctions you may have with our products. Please let us know as much detail as possible about the symptoms and condition.
Email: japan@ghkairsoft.com
Products officially sold by GHK Japan have a 13-digit JAN code starting with 458956 printed on the outer box.
Parallel imports are not eligible.
Please note that we cannot compensate for any paint, surface treatment, engraving, or other appearance issues that occur during repairs or part replacement.
In cases other than initial defects, shipping fees and other charges may apply.

Regarding exterior finish:
We take great care in manufacturing our products, but there may be traces of operation due to inspection and functionality checks. Also, please be aware that as these are overseas products, there may be uneven paintwork and poor molding precision.
Since this is a model/toy-type product, it does not have the strength or durability required for safety. Therefore, please handle it gently and do not apply excessive force.

[Notes]
The Japan Premium Ver. uses a CO2 power source that is less affected by outside temperatures, achieving powerful blowback and stable initial velocity.
This product has a nozzle setting optimized for CO2. If you use a magazine for HFC134a (freon gas), the initial velocity will drop dramatically and the trajectory will be unstable.
▪️The V3 uses many new parts, so the following parts are not compatible with previous models: Bolt Carrier / Recoil SP / Recoil Buffer / Loading Nozzle / Valve Knocker / Hammer SP
▪️Please be careful not to injure yourself during maintenance.
▪️As this is an overseas product, the outer box (gift box) may be damaged or crushed. Please be aware of this in advance.
▪️New magazines are tight to install and remove. They will break in after a few attempts, but scratches and minor damage may occur. When installing or removing a magazine, it will be relatively smooth if you pull it lightly toward the trigger.
■Please purchase only if you are able to adjust or repair the product yourself if there is a problem after purchase.
■This product is intended for ages 18 and over.
