I purchased one of these a little over a year ago after contacting the company. I had purchased a 930 JM and wanted to do a little upland hunting with it, but was unable to get a hold of Mossberg to see if they could ship me the part I needed. Long story short, these guys shipped me out the product quickly and I’ve ran over 1000 rounds though my 930 using this cap, and it has always worked 100%.
As a side note, this product works with a factory tube spring or you can simply order an extra one and cut it to size -what I did.
Great product, and a great company. Thanks again guys.

Wondering if this adds +1 to a JM Pro 940?
