Overwatch Precision mentions explicitly on their product page compatibility with the Heckler & Koch MP5, SP5, and other common MP5 variants. Additionally, the OMag is built with a proprietary polymer composite that Overwatch Precision promises to have unmatched reliability and durability. It’s also engineered to feed well with full autos like the MP5K weapons platform, making sure you can Mag Dump without issue.

It seems that Overwatch Precision is set on giving the growing roller-lock community a functional and reliable alternate to expensive steel mags to which they have become accustomed. Bonus points to the OMag because they are entirely end-user serviceable, being easy to tinker with is always a huge plus. Let’s jump into the official product specifications they’ve got listed on the website.
