I'm getting ready to order a mannors stock in the group buy section and I have a question about bottom metal. The options that manners gives you is: Badger, Seekins, ADL,BDL and there own system(short action only. My donar action came from a stainless SPS so im not sure if this is an ADL or BDL. Also I would like to go with the badger or seekins but they are a little on the pricy side. Is there anyone who makes a drop in adl/bdl drop in mag system a little more affordable than the two I mentioned? If I bought a Mag from Remington would it work with the bottom betal I have now? I have a hinged floorplate(I realize it would take some mods). What are my options?
