USED Factory Ruger Mark 2 Bolt
These have WIDER ears than MK3 and MK4 bolts (no finger pinching)
This is the Straight ear version (My personal favorite)

Includes;
Recoil Spring Assembly
Firing Pin & Stop Pin
Rebound Spring & Support
Extractor & Extractor Spring and Plunger

These will work in Mark 2, 3 and 4 pistols (Mark 3 will need LCI removed)
These will work in Mark 3 but will need LCI removed from receiver
These will work in Mark 4 but you will need a MK4 recoil spring assembly or a Volquartsen VC3RS
ALSO on Mark 4 the rear bottom sides may need some clearance work if they are rubbing your lock plate
