Won't work, not without a lot of heavy modification to the plastic, and basically cutting in half.

It just takes a little work with a wooden dowel wrapped in sand paper to modify them to fit DA's tubes.
Also true, I had to do that to my mag-fed with a fab grip.
However, I was referring to the length of tue tube, not the diameter.
