SHS Ball Bearing Spring Guide For Version 2 Ver. 2
The CNC machining process SHS uses produces very high quality and precision made spring guides.  The ball bearings allows your spring to twist as it decompresses which puts less pressure on the spring.  The bearings also improve your ROF and they act as spacers to increase the FPS.  The stainless steel and quality bearings make this spring guide durable, reliable, and sure to keep your gearbox running for a long time.
