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 Rock Island Compact. You will need to fit the lugs on the top of the plug (shown in alternate image).

This kit does not work in a Metro Arms Compact.

This kit uses a 1/4" diameter guide rod, flat wire ISMI spring, and our fully machined reverse plug. The spring that comes packaged with the kit is a 22lb, which works perfect for .45 ACP. We do have 16lb springs available for smaller calibers that we could swap in per customer request.

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.
