SHS Aluminum and Stainless Steel V3 Spring Guide

These SHS spring guides are the same as the full stainless ones sold by SHS, HC, Core, etc but the outer tube and cap are made from aluminum instead of stainless. The base and threaded core section are still stainless. These are for version 3 (AK47, AK74, UMP, Steyr Aug, MP5K, G36, SIGs [for this part], and others) gearboxes. The main purpose of this upgrade part is to release torsion buildup in the spring that can cause premature failure and poor performance. This also increases the consistency of the velocity which improves accuracy. Because of the thickness of the ball bearing it also acts as a spacer which increases velocity.

Specifications:
- Spacing thickness (the distance the guide spaces the piston forward measured from the back of the guide): 6.67 mm (.264 in)
- Stainless steel construction
- 8 ball ball bearing
- Improves spring life
- Adds velocity
- Increases velocity consistency
