These FLGR sets include a spring plug with a "Short" nose to match up to barrel bushings with a .090" thick flange, such as factory "GI" style bushings..
These stainless steel one-piece full length guide rods are top tier units. They come with a matching stainless steel spring plug which has a long nose that matches the flange thickness of my Radial Bore Barrel bushings. The guide rod flanges are correctly shaped and sized as well as having a proper radius around the flange's periphery. They are also correctly relieved so they clear the barrel feet and link in operation. The guide rods are also drilled for a take down pin, assuming you want to use the take down pin method of disassembly and your slide's spring tunnel is machined to accomodate it.
