BDL, ADL, and DBM simply refer to the magazine system. BDL= floorplate, ADL= blind magazine, DBM=detachable box magazine.
The P, CDL, Classic, SPS, Mountain rifle, Sendero, and many others are all versions of the BDL. Any aftermarket stock sold as BDL will fit all of the above as long as barrel contour is the same.
Most BDL's that were manufactured have a certain set of features that many think must be present to call it a BDL, but over the years there have been so many variations made that it can be confusing. When you get right down to it they really only describe the magazine system.
