Nice and simple to use and clean suppressor in .22, but it will also handle .17HMR and .22 Magnum as well. So, there you go. We have sold a few already and reports are that they eat and eat and eat without complaint. Come see us. We try to make NFA stuff as painless as possible, and believe me, our prices are WAY better than you will find at any kiosk...and we don't offer to comply with brace rulings like those places did.
