AntTech KGS: MK18

Unveiling the "AntTech KGS" series – where craftsmanship meets rugged precision. These pre-builds are a testament to the dedication we put into every detail, ensuring a one-of-a-kind experience for enthusiasts and professionals alike.

 

Key Features:

VFC M4 Base:

Every "AntTech KGS" is built off of a VFC M4 base. Renowned for their top tier externals, this platform possesses a realistic Mil-spec aesthetic and feel while having optimal internal specs for the fitment of Polarstar Engines.

Polarstar Kythera Engine and Gas Stock (UGS/CGS):

As the designation "KGS" (Kythera Gas Stock) suggests, these pre-builds are powered by the groundbreaking Polarstar Kythera – a mechanical HPA system engineered for realism, precision and durability, and the UGS/CGS - a reliable, easy to use, gun mounted regulator that frees users from wearing a cumbersome tank and line on their back.

Each Kythera is carefully tuned to provide consistent, reliable follow-up shots in even the most adverse weather conditions.

The match-grade AR-15-inspired trigger ensures a responsive, crisp trigger break/ reset. This is achieved through polishing and finely tuning the trigger and disconnect sears. The result is minimal creep after the wall and a positive tactile reset.

The UGS (Universal Gas Stock) allows for fast and easy air source changes on the fly. While the "AntTech KGS" includes a stock rail and HPA Tank, users may opt to run either of the two C02 adaptors offered by Polarstar Airsoft *C02 adaptors and C02 Stock Rails not included*. The upward facing adjustment screw makes tuning the regulator's PSI easy, while also being "lockable" via running a zip-tie over the adjustment hole.

The CGS (C02 Gas Stock) is the same exact regulator as the UGS except it is housed inside of a modified AR-15 Buffertube! The CGS is the perfect option for those who are willing to sacrifice some air capacity for the most realistic aesthetic! The CGS is capable of using Polarstar's 12g or 33g C02 Adapter for CGS. We highly recommend the 33g over the 12g, and offer 33g C02 Cartridges for sale.

AntTech KCL (Kythera Cocking Lever):

The AntTech KCL (Kythera Cocking Lever), allows users to manually reset the Kythera's mechanical trigger group via the charging handle, providing a more immersive experience. As a failsafe, the AntTech KCL retains the system's ability to be reset via the Reset Cable directly from inside the grip.

Maxx M4G / GBB Bucking and Barrel:

The Maxx M4G allows the AntTech KGS to accept a particular spec of GBB (Gas Blowback) bucking and inner barrel. Additionally, the inlet adapter for the hop up chamber is custom fit to each AntTech KGS using a mini precision lathe to ensure perfect alignment between the hop up chamber and gearbox shell.

Maple Leaf Wonder Bucking:

The GBB style bucking has proven to be more optimal for the Kythera engine over AEG spec buckings. The Maple Leaf Wonder Bucking offers extended BB retention while funneling the BB dead center under the concave contact patch; perfect for the aggressive closed-bolt operation of the Kythera engine.

Maple Leaf Crazy Jet Barrel:

One of the only two inner barrels on the market compatible with the Maxx M4G hop up, the Crazy Jet Barrel features a unique crown feature that warrants the name "Crazy Jet". The Crazy Jet redistributes high and low pressure air propelling the BB through the barrel to facilitate a straight and stable trajectory after the round exits the muzzle. This system was designed to mitigate the volatile nature of GBB systems, but has proven to also produce gains for HPA and AEG builds thanks to the M4G!

Chopped Stock *UGS Variant*:

Each UGS variant pre-build will include a chopped G&P Air Tank Stock and UGS Stock Rail allowing you to achieve a shorter length of pull!

*Performance specs were derived by averaging the chronograph results of multiple "AntTech KGS"'s during the quality control phase*

 

Optimal Ammo for Ultimate Experience:

To fully unlock the potential of the "AntTech KGS", we recommend using BLS, or EliteForce BBs ranging from .32g to .45g in weight.

Do note that the Kythera engine is strictly mechanical, thus the dwell settings are not tuned via an FCU. While the standard operating procedure for an electro-pneumatic HPA engine may be to adjust your FCU settings to the desired BB weight and muzzle velocity, this is not the case for the Kythera engine.

These pre-builds were tuned to work optimally at around 1.45J with .32 - .40g BBs; however, it is highly encouraged to test different BB weights and PSI settings until you find the performance that best suits you!
