PGP Bolt Rebuild Kit
$15.00
Replacement O-Ring and detents kit. Kit includes two 1/4" bearings and spring to replace or repair your current detents as well as a replacement O-ring to replace the commonly worn-out O-Ring which provides a seal between the bolt and barrel.
After testing various spring rates and sizes, we determined this spring type is most likely to hold your bolt closed and in place when firing one-handed and not make the cycling process too tight. However, this result may vary depending on the amount of wear around the bolt detent holes and the inner diameter of the barrel tube itself. These springs have a corrosion resistant zinc coating with a maximum load of 6.25 lbs and a spring rate of 28 lb/inch.
