Springfield® Prodigy™ 4.25" Guide Rod Kit!
The takedown hole in the guide rod allows for easy disassembly/reassembly. The head of the guide rod has smooth beveled edges to make for a seamless look. All kits are drop-in. This guide rod kit is made for the Springfield® Prodigy™ 4.25". This kit uses a 1/4" diameter guide rod, flat wire ISMI spring, and our fully machined reverse plug. In independent testing, ISMI spring have endured in excess of 100,000 compression cycles. We don’t recommend going that long between changes however. With an ISMI spring, practice routine maintenance and change it once a year.
