So I've got a dozen or so factory SA mags that I've installed Tripp Super7 spring/follower kits in. I've been thinking about adding some bumpers to these mags. Can this be done? My mags do have two holes drilled in the bottom that look like they might be threaded (but then again, might not). What would I need? Thanks! |
