Anything can be made to work IF you are prepared to throw enough time ,effort and money at it. Not knowing the OPs skill level, etc., etc.,etc., I was playing it safe and voicing my opinion as to a ready made solution to his problem. My 112BVSS laminate stock now sports an extended blind mag set up that "looks" like a DBM from a distance. I dare say it could be made to work in the Choate SU or UV stock with a little inlet work. You could probably install a CDI DBM in that stock IF you removed the Choate trigger guard and reworked the stock to accept the CDI guard. Should be doable but I would run it by CDI first.
