Description
HKP HK MR556/HK416 FFRS Retaining Spring
The retainer spring retains the handguard locking pin on the free floating rail system (FFRS). These can become damaged with the removal of the handguard screws. Once the spring is damaged, they require replacement as repairing to the original form is difficult.
