What length does the cut start at if measured from the breech to muzzle?

It is just the right distance for a carbine length gas system's FSB. If you need it for another reason I can measure when I get home.

It is about 7 1/8" from the front of the upper and 2 3/16" long. HTH.

Yes thanks, from what it says, I can have no more the 7" rail to fit the block.
