How to fit a Magpul magazine well DBM kit (MAG497) for a Hunter 700 stock to a non-Magpul Remington 700 BDL stock

Ever thought about if you could use a Magpul DBM kit meant for a Hunter 700 stock on a non-Magpul 700 BDL stock? Well, you can, and it is fairly easy to do.

Years ago, when Magpul came out with their Hunter 700 stock and magwell that accepts AICS pattern magazines, I quickly bought one and fitted it to a Remington 700 tactical action I had because I just hate using the traditional top-loading bolt-action rifle magazine. Well, a few months later, I traded the rifle with the Magpul stock for a 1911. I really missed having a heavy-barrel 700. But I was never crazy about the Magpul Hunter stock, just thought it looked too plastic and weird.

Anyway, fast forward about 9 years to present, when I recently picked up a good used Remington 700 tactical in the factory Hogue stock with a brand new Magpul DBM kit thrown in the deal. I took it to the range and shot it as is and quickly decided that I was going to get a nicer stock and fit the DBM kit to it to take Magpul AICS pattern mags. I thought about going the chassis route, but chassis aren't cheap, and I like the look of a traditional rifle stock. I ended up finding a good used HS Precision police sniper stock https://hsprecision.com/product/pst012/.

At first, I was hesitant to start work on this project as I didn't want to mess up the stock or be unhappy with the results. But I was determined, and I researched online and found others who had done the same project. It went pretty smoothly and fast. But I learned some things that I would do differently if I had to do this again. So here is my procedure.

Tools used:
A Dremel with grinding stone (932) and large flat files were used. In hindsight, I forgot that I had a Dremel chainsaw sharpening set (458) with smaller diameter grinding attachments that would have worked better to make sharper corners.

For the stock:
You don't need to remove much material from the stock. I didn't need to remove any material from the aluminum bedding block. The only spots on the stock that needed fitting were the front, back and sides around the magwell. I used the dremel to open up the corners around the front and back of the magwell. And the flat files to remove material from the sides of the magwell.

For the Magpul magwell DBM kit:
You need to remove material from the top front and from the sides, where there are some tabs that stick out. Also, behind the rear magwell "spine" a little. You don't need to remove any material from the rear magwell "spine" that sticks up from the magwell. I removed a little before I realized you didn't need to. Be careful about removing too much material on the front part of the magwell. If you remove too much the magwell will go too far into the stock and the magazine won't lock into place because it will be pushed out by the bolt.

Overall, while I could have made it look cleaner with smaller dremel files and also not scratched up the Magpul kit removing the side tabs, it functions perfectly and feels very solid.

I cut HS stocks for the M5 inlet which gives you dozens of different manufacturers to choose a DBM from.
