Silverback SRS Open Piston Sear

SRS Open Piston Sear Inspired by an original idea of Bruce Palcko, SRS user. This peculiar design allows the piston end to lock effortlessly on the sear, making the bolt operation even smoother. On the other hand, you will have to manually maintain the spring guide in position when reinstalling the buttplate. CNC Stainless Steel. Ref: SBA-PTS-03
