Long time lurker, first time poster. I have a Ruger 10/22. I would like the bolt to hold open after the last round. Some research has found this product that is a drop-in replacement and doesn't need any magazine modification. This seems like the best solution from my research. Anyone have any further advice or experience in this area? Thanks.
