G&Gs SR-25 DMRs are powerful AEGs, but you can get much more out of them with a PolarStar HPA F2 installed. This nozzle is a replacement part for the one that comes with the F2 engine, and it works perfectly after installation. PolarStar uses durable aluminum to make this nozzle and coats it in red paint.
The nozzle is slightly longer than the M4s nozzles for better fitment since the SR-25 is of a different design. Youll notice your shots go farther, hit harder, and stay consistent compared to using the stock hardware. Theres one O-ring on the nozzle, which helps you achieve a perfect seal.
