The Ruger 90655 Magazine Well Insert Assembly transforms your PC Carbine into a pistol-fed platform that runs on standard Ruger American Pistol 9mm magazines. If you already own a Ruger 9mm pistol, this insert unlocks genuine magazine interoperability—no need to stock separate carbine mags. It's a smart, cost-effective upgrade for shooters who want to consolidate their ammunition ecosystem across pistol and rifle.
Built from glass-filled polymer, the insert combines durability with a clean, flush-fit design that won't snag on gear or look out of place on your carbine. Installation is straightforward and uses the same hex wrench that ships with your PC Carbine. This is genuine Ruger factory engineering, manufactured in the USA, so you know it's engineered to spec and backed by Ruger's reputation for reliability.
Whether you're setting up a dedicated 9mm carbine for home defense, plinking, or training, the 90655 gives you the flexibility to share magazines between your pistol and rifle. The robust polymer construction handles repeated use without compromise, and the flush profile keeps your PC Carbine's lines clean and functional.
