I recently acquired a Dpms oracle in 223 as my plinking gun. I had an extra magpul CTR stock commercial buffer tube size. When I had it on my rock river it fit very nice and snug when activating the clamp on the stock. With the Dpms it seems a bit wobbly. Is This common on their buffer tubes?
Normally you'd expect the DPMS to also have a commercial diameter tube. Sounds like this one has the smaller diameter milspec tube which would cause a sloppy fit using a stock for the larger size.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.

My DPMS came with the commercial tube. I actually bought the milspec setup since I got a good deal on a used SlideFire stock and it won't work with commercial tubes. I have yet to install it though, given .223 became worth it's weight in gold recently
