These Rocket spring guides are the same ones sold by SHS, ZCI, and dozens of others. These all stainless steel ball bearing spring guides for version 2 (M4, M16, MP5, and variants, G3, and M249) 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 (.263 in)
- Stainless steel construction
- 8 ball ball bearing
- Improves spring life
- Adds velocity
- Increases velocity consistency
