I've been planning to put together something like an SDM-R.
I like the idea of the MGI for the flexibility to change configurations. Will the MGI offer the same level of accuracy with a good heavy stainless match barrel as a quality forged reciever like a CMT or LMT? How about compared to a Larue or Vltor Billeted Upper? Are there any "ideal" fitting dimensions for the barrel extension on a barrel to be used with the MGI upper? Who would be a good source for an SDM-R configuration barrel set up to be used in an MGI upper (no barrel nut, etc.)? |

Well, twl has stated that Advanced Barrel Systems uses an MGI QCB upper to accuracy test their barrels, and sub-MOA groups seem to be the norm for them, so I suppose there's little to no practical difference in accuracy.

It should have the potential for more accuracy-it's free-floated. I'm using one of the older MGI models as a basis for a RECCE. Make sure the barrels you buy for it come without the barrel nut and delta ring-you want them totally stripped behind the gas block.

Don't most barrels come standard with a barrel nut, and why would it be a problem? Can't you just slip it off. |

You can, but for me it was a pain to remove the gas block.
