They're great as far as push pins go - KIDD Innovative Design Receiver Push Pins For Ruger 10/22

Got these for my Faxon Receiver and BX Trigger group. Everything else on the build is Kidd and these were fairly priced so I picked them up. They're very nice quality and fit in with no issues. They have just enough tension to not fall out but are easy to remove if you want to pull off the trigger group. No play between the trigger group and receiver. Would definitely recommend them.
