Discovery/Maximus TKO ModTKO1TKO1

The Discovery and Maximus air rifles by Benjamin (owned by Crosman Corp.) have been a very successful product line. These entry level PCP air rifles are capable of very good accuracy and power. That power comes at the expense of a quite loud rifle. The TKO Moderators have been specifically designed for the valving and power output. The TKO Discovery and Maximus Moderators have been extensively tested since the introduction of these rifles in 2008, and are at the pinnacle of performance for such a small diameter airgun moderator.
