This adapter lets you attach AR15 handguard on to any MILSIG marker without any modifications. Now you can add shrouds from popular brands like Fortis, Noveske, Troy, Crown Arms and more. Compatible with MILSIG M17 and Valken.
NOTE: Depending on the handguard barrel nut internal diameter size that you are installing, your barrel may not work. If the barrel nut you are using is 1.1” or smaller your stock barrel will not fit. You will need to get a replacement barrel that is 7/8 outside diameter. Lion Claw Barrel is an example of the barrel type you can use.
