I have a complete DT E316 and I used a DT rifle kit to build with . Both rifles work great with no problems . I have not used the sport but the 2 big differences I see from the E316 is no M4 feed ramps and Light Weight Barrel/pencil . If I had to chose between the DT sport and the M&P sport I would take the DT sport . Only cus I have Del-ton products and Have no issues with them .
That all being said I agree with Quentin2 to the point that I would step up to the E316 at minimum . Right now you can get a great deal on a PSA complete rifle build kit with Magpul CTR stock minus the stripped lower . You then should be able to buy a stripped lower and put the whole thing together for under $900
