The AntTech Gas Stock Adapter for VFC 416A5 matches the non-standard metric threads found on newer VFC 416A5s, allowing you to mount a Type 2 (TM Spec) Polarstar Gas Stock!
Made of durable CNC aluminum, this adapter ensures your Gas Stock stays on nice and tight.
Why This Product Exists:
Polarstar makes their Gas Stocks (UGS/CGS) for two types of M4/416 receivers, Type 1 (Real Spec) & Type 2 (TM Spec).
A Type 1 Airsoft receiver mounts stocks via a large threaded hole called the buffer tower. This buffer tower shares the same thread dimensions as its Real Steel counterpart. Very few Airsoft M4s actually feature a Type 1 receiver.
A Type 2 Airsoft receiver mounts stocks via a long M5 screw whose head is retained inside a TM Spec buffer tube and is threaded into aback of the gearbox.
The VFC 416A5 originally featured a Type 1 receiver, so we would use a Type 1 (Real Spec) Polarstar Gas Stock when building an AntTech KGS.
At some point after the VFC 416A5 was released, there have been some production runs in which the receivers underwent some subtle changes. Most notably, the buffer tower and buffer tube changed to now have non-standard metric threads. This means that neither the Type 1 or Type 2 Polarstar Gas Stocks fit on it… Until now!
