Frequently Asked Questions

How do you field strip the Rock Island Arsenal RIA 5.0E?

To field strip the RIA 5.0E, first ensure it's unloaded. Align the dots on the slide and frame, then remove the slide stop lever. Separate the slide from the frame. Compress the recoil spring, insert a paper clip through the designated hole to hold it, remove the pin connecting the barrel block, and then remove the barrel and recoil assembly.

What makes the RIA 5.0E's operating system unique?

The RIA 5.0E does not use a Browning-style tilting barrel. Instead, it features a vertically traveling locking block system. This system locks the barrel and slide together and is actuated by the guide rod's angled surface, allowing the barrel to unlock and operate independently of the slide.

What type of magazines does the RIA 5.0E use?

The RIA 5.0E uses 17-round magazines that are essentially Beretta 92 magazines. The magazine catch notch is slightly modified to fit the RIA 5.0E's higher magazine release button position.

Where is the RIA 5.0E manufactured?

The Rock Island Arsenal RIA 5.0E is manufactured in Cedar City, Utah, USA. This is indicated by markings on the frame, including an American flag emblem.
