I'm very curious about this as well but I don't think it will without inletting. Readings the product description on Magpul's website, it says you remove a spacer from the stock and then drop the magwell/trigger guard in. I'm guessing that spacer is the difference between the standard BDL bottom metal and the new magwell. Considering the decent price, I might get one and see if it will fit my H-S Precision.
