It offers a quick and simple attachment of your suppressor and less felt recoil when the suppressor is removed. Shoulder interface: 25-degree taper for use with SIG SAUER Taper-Lok barrels. (A 90-degree version of this item is available for non-SIG SAUER barrels) Please check with your local and state municipalities for any further regulatory requirements. It is your responsibility as the buyer of these components to make sure you comply with all NFA rules and applicable laws.
