Take a look at Atlasworxs, they make a variety of DBM for different firearm manufacturers.
If you email them, they'll send you a footprint for the DBM and you can check sizing and see how much, or if, you'll need to modify the stock.
A positive selling feature for Atlasworxs is that they're in Australia, and the AUD to CAD conversion works in our favour - unlike USD to CAD.
