HKP 1st Gen Roller Retainer Plate To Spring Upgrade
This Action 3 roller retainer spring replaces the oval-shaped roller retainer plate for all 1st Generation bolt heads.
HK made a wire spring as an upgrade for later production bolt heads to improve the longevity of this part. This roller retainer spring is 100% retrofit-able to the old-style (plate-style) bolt heads.
Note: Always replace the roller retainer pin when replacing the roller retainer spring.
