Kidd innovative design lr bolt buffer - ruger 10/22 - KIDD Innovative Design LR Bolt Buffer For Ruger 10/22

Hello Ruger, 10/22 fans! Factory original part called the "Bolt stop pin", all steel. While I firmly believe the Ruger 10/22 is one of the best little semi autos ever made, in doing my upgrade this replacement part made sense to me. The steel-on-steel contact you get with the factory original steel stop pin doesn't make sense to me. Now there are two aftermarket bolt stops I have found; this is one of them. The other is a one-piece solid plastic pin. The Kidd design here has a small alloy pin covered in a foam insulation that seems more conducive to punishment than the factory original or the other aftermarket replacement. I have put over 500 rounds thru my carbine & haven't seen any indication of wear on the buffer. However, that is only 500 rounds, hence the reason for the 4 star rating.
