Will a metric barrel mate with an inch receiver without problems? Any advice on proper headspacing ?
Thanks Bruce

Same threads, headspace same procedure as a metric/metric unless the barrel overtimes in which case use a breeching washer per inch headspacing procedure.

Exactly. You may not even notice a difference at all. If you DO happen to overtime, note that you won't be needing a standard Inch breeching washer, but something about a tenth as thick, probably... some vendors offer these ultra-thin "breeching" washers, or make your own from shim stock... somebody even recently suggested a beer can. :tongue:

Going in the other direction, an Inch barrel on a Metric receiver WILL need a breeching washer, but that's just standard procedure when working with an Inch barrel.
