I have a few ADMs. It’s 219 right now. Use code Superior and you can get it for under 200.

That being said, the ADM is about 6oz lighter. The barrel runs about .655 near the throat then tapers down to .625 near the gas block. The gasblock is .750 then after that it tapers back to around .625 then maybe .600 near the muzzle. These measurements aren’t exact. I did use a caliper but I’m saying the measurements off the top of my head.

The .750 gasblock is odd for this profile but I mostly use .750 or .875 superlatives. I like to have redundancy on my builds so I can swap/replace parts easily. Basically, my back up parts became new builds. And I may need to transfer those back ups into my main rig. That being said, .750 block was a great option for me.

Good hunting.
