Modifying a ACM Magpul PTS 20LR PMAG for a VFC SCAR-H

Overview
Since the release of the Vega Force Company Mk17 SCAR-H the owners have been forced into buying the expensive VFC FN SCAR-H magazines. Normally this isn't a huge issue. VFC SCAR-H magazines come in a pack of 3, and cost around $90 USD for the set. However, that still works out to $30 per magazine. In comparison, a M14 owner can expect to pay around $25, as can a SR-25 owner.
Editor's Note 2017: Prices have significantly fallen for VFC SCAR-H mags, but SR25 mags can be found for much less.
Accessoriy Modification
On the left is a standard G&P SR-25 magazine. The area in question is the stabilizer in the middle of the mag.
In the middle is a modified 20LR PMAG. With the rib in the VFC magwell (pictures in the next section) I cut a channel into the mag itself to avoid having to modify the rifle (which I did anyways afterward see THIS GUIDE about the modification).
On the right is a standard VFC Mk17 SCAR-H magazine. As you can see the stabilizing rib is much thinner and only occupies the right side of the back instead of the entire back section of the mag like on the G&P SR25 magazine.
Externals Modifications
On the left is the stock VFC SCAR-H magwell. You can clearly see the offending rib that makes the entire rifle proprietary. On the right is a test magwell from a DBOY SCAR-H (VFC clone). As you can see, I have dremeled, filed, and sanded the rib away.
To modify the Magpul PS 20LR PMAG it’s quite simple.
First - mark the back of the PMAG with a sharpie or pen using the magwell rib as a guide.
Second - take two standard heavy duty dremel cutting wheels (or 4 standard wheels) and bolt them together in the mandrel.
Third – Carve a channel into the back of the magazine. Go carefully and check the depth required after each pass. Removing too much material will result in the magazine wobbling back and forth in the magwell and may cause the mags to miss-feed or not feed at all.
I cannot stress this enough. BE VERY CAREFUL! If you remove too much material from the mag you WILL ruin the mag so that it no longer feeds in a SR-25 OR SCAR-H.
BE VERY CAREFUL
Performance
There really isn't much to say.
If you did it right the mag should feed in a SR25 or VFC SCAR-H
Final Thoughts and Upgradeability
Not too many people out there have SCAR-H's so it's already a unique platform, but there are even less that use PMAG's.
This mod will also work for the DBOY Mk17 SCAR-H since it is a clone of the VFC, as well as the Echo 1 ASC-H (aka SCAR-H) since it is a rebrand of the DBOY Mk17.
