I found this post I made 12 years ago. Thought I'd repost it for informational purposes.Â
Its raining here today so I got out my Craftsman thread pitch gage and my Frankford Arsenal digital calipers and decided to do some measuring of the large and supermag barrels. I'll post my results below. All measurements made at frame end of barrel.
