PC Carbine Trigger Spring Kit

PC Carbine Recoil Spring

After the Ruger PC Charger was introduced, we had issues with platform cross-compatibility. Customers continued to buy the PC Carbine parts and install them into the PC Charger, inevitably getting mixed results. We decided to stop selling these items 

We apologize for any inconvenience.

We do still offer everything else sold separately on our website: Ruger PC Carbine Accessories
