Polarstar UGS End Plate Assembly

The Polarstar UGS End Plate Assembly is a precision engineered upgrade designed to expand compatibility and improve the overall integration of Polarstar UGS systems on M4 series airsoft platforms. Machined from durable aluminum, this end plate provides a strong and lightweight interface between the rifle receiver and the Unified Gas System. Built to fit the original Polarstar UGS for M4 platforms, it delivers a clean and secure mounting solution that supports stable alignment and long term reliability. For players and technicians working with HPA airsoft builds, this component plays a critical role in ensuring proper fitment while maintaining the streamlined profile expected from a professional level setup. Beyond standard M4 UGS applications, this end plate assembly allows R3 series rifles to be converted for use with the UGS 2.000 HPA system and milspec stock rails. This conversion removes the need for external stick on rails, resulting in a cleaner, more rigid, and more realistic rifle configuration. Cross compatibility with both Type 1 and Type 2 UGS systems makes this part a versatile solution for players upgrading or reconfiguring existing Polarstar builds. It is not compatible with the HK417 UGS, ensuring correct application within supported platforms. Ideal for airsoft technicians, competitive players, and milsim users, the Polarstar UGS End Plate Assembly supports reliable air delivery, clean stock mounting, and a professional internal layout. Whether you are upgrading an existing HPA rifle or planning a new Polarstar build from the ground up, this component enhances system flexibility while maintaining the durability and performance standards Polarstar is known for. For players searching for Polarstar UGS parts, HPA airsoft upgrades, or M4 HPA conversion components, this end plate assembly provides a purpose built solution that improves fit, function, and long term system integrity.
