Rock Island Competition Magwell

(7 reviews) Write a Review

This magwell is for the Rock Island pistols that have the "tail bone" style frame. This is a black anodized aluminum magwell with a much larger funnel and weighs almost the exact same as the factory steel magwell. Our design has two set screws that contact the steel frame as opposed to the factory set screw that pushes on the mainspring housing, potentially adding weight to the trigger pull. (This magwell is designed to work with Remington and MBX mags. Short mags such as Factory supplied Mec-Gar will not work with this magwell.)

May not fit frames with front strap checkering

Weight 2.4 oz

Black anodized finish

    Fit and finish were exactly as described. A couple file strokes and the fit was perfect. That was described in detail in the video. I am also glad it did not say Hayes on the bottom like in the pic I saw. I am not a big Billboard on my stuff kind of guy. Thank you for a great product.

    Fantastic magwell. It was a perfect fit. Very little shaping on the frame at all. Basically just rolled the edge. Fit better than my factory and was a perfect fit for my VZ grips. Please keep making upgrades for the Rock Island double stacks.
