Easy installation. shorter, lighter less bulky than other adapters for the resonator - Yankee Hill 431536A Mini QD Flash Hider 5.56 NATO Black Phosphate 1/2"-36 Tpi

This adapter seats on the step behind the barrel threads. It also does not require clocking and therefore does not require barrel shims. Simply screw it on and torque to 20-30 ft-lbs. It's lighter and less bulky than the Phantom version but still works with a variety of YHM suppressors, including the original Resonator that I own. My Resonator installs and removes easily.

Without having had a chance to get it out to the range for live testing, I can't say more. Based on the above I recommend it, especially for AR pistols and similar platforms where the weight and length of the full size adapter may be more of an issue or firearms that are seldom fired suppressed and you want a smaller adapter.
