Description
The Ruger 90654 Magazine Well Insert Assembly is a factory flush-fit magazine well conversion designed exclusively for the Ruger PC Carbine. This insert allows the PC Carbine to accept Glock-pattern 9mm Luger magazines (and is also compatible with .40 S&W Glock-pattern magazines), giving shooters access to one of the most widely available magazine platforms on the market.
Made in the USA from rugged glass-filled polymer, the insert is built for strength and long-term durability. The flush-fit design keeps the rifle’s clean factory profile while quickly and easily swapping out the magazine well to change magazine compatibility. Installation requires the 5/32″ hex wrench that is included with the PC Carbine from the factory.
Whether you’re looking to take advantage of the wide variety of Glock-pattern magazines or just want a spare/replacement mag well for your Ruger PC Carbine, the Ruger 90654 is the correct factory part for the job.
