Universal Fitness foldable treadmill

Universal Fitness foldable treadmill fully functional, works great but it’s missing the key (emergency stop) that can be ordered on Amazon and the foam on the handle is beat up. $75.
Cash is king but I'm open to trades or trades+cash for rifles of any condition (Even with old cracked furniture, rusted beat up barn guns, try me!) If it's just taking up space, you might as well trade it for stuff you can use! Have PAL
