For rugged obsidian 9 - Kaw Valley Precision 3 Lug Barrel Adapter

So far I have bought about half a dozen of these 3 lug barrel adapters. These are reasonably priced alternative to the rugged ones, and the only difference is that the KVP one does not have the go no-go feature. I use a little rocksett on these with standard torque and it is good to go. Will be buying more as soon as my dissent 9mm upper ships. Also these work with the Griffin 3 lug mount on a Bushwacker 36 just fine. Both cans stay aligned and no baffle strikes even under rapid fire. Only complaint is that the AR9 barrel is a little larger in diameter and you can see the step down going to this smaller diameter device. It has no wrench flats and you have to use the special tri lug wrench to install it. I have no issues with these design choices since it will go on dedicated suppressor setups where you don't notice it too much.
