Have been wanting DBM's also. I have 3 stocks, all blind magazine , and the 2.275 spacing. I got in touch with Jeff at CDI precision gunworks, down in Florida.
Sent all three to him today. It's $60 a stock for him to inlet. This is for his bottom metal that he makes, which will accept the AICS mags.
The stocks were a Bell and Carlson Tactical Meadlist A2 ; a Choate Ultimate Sniper; and a LVT (black,black,black) from Fred at Sharp Shooter Supply that has, I think aout everything added to it you can.
It might be a simpler, and cheaper way to go. Especially if you get a bad oops! You could become a member (cheap price for what you get) and then sell
your extra parts and pieces here (which is a members only classified).
Maybe some thing to ponder.
Greg
P.S. he does have metal for the new longer spacing
also, it cost $46 to send thru UPS. $10 to wrap,( bubble wrap) and package ; $ 36 to ship with $1000 insurance
