FWIW, I ordered a direct thread 5/8x24 DA part # LT302 mount for my Nomad LTi XC earlier this week and got it yesterday. Screwed the Xeno adapter off and the direct thread adapter on and put it on my dig. scale the LTi XC weighs 11.6 oz with the direct thread mount which is a few ounces lighter then it was with the Xeno + Omni brake and I guess it's supposed to be slightly quieter with a direct thread.
Played around with it on my 300blk AR pistol in my shop and swapping back and forth between the new Nomad my SAS 338 Vengeance, and Banish 30 (in its full length) the Banish 30 isn't even close so didn't bother with that one after a couple shots and to my ears, I could really tell no difference between the much bigger 338 Vengeance and LTi XC they both were holy shit that's quiet. The brass hitting the concrete floor seemed louder.
