Yankee Hill Kurz QD Adapter | 1-3/8-24 | YHM-3051

The Yankee Hill Machine Kurz Q.D. Adapter (YHM-3051) is an accessory designed to shorten the Phantom Q.D. mounting system on suppressors that use 1-3/8-24 rear mounting threads. It is described in manufacturer materials as machined from 17-4 stainless steel and finished with a matte black oxide. The Kurz adapter reduces overall mount length by approximately 0.675 inches, providing a more compact and weight-conscious configuration for compatible suppressors.
