Designed specifically for varminters and target shooters using the Hornady .17HMR or .17HM2 round, our all-stainless suppressor isn’t any .22lr suppressor dumbed-down for use with this hot round. It is purpose-built to live up to heavy use in the longest varmint hunts. The Gemtech HMR suppressor is a very discreet, low-profile thread-mounting unit that provides OSHA-safe hearing protection in a package only 7/8” in diameter and only 5 inches long. The HMR suppressor attaches to most common .17HMR barrels by standard 1/2-28 threads. Gemtech can thread your barrel for a nominal charge, or a local machinist may follow our instructions and thread it locally.
