.HERE you go.A smooth (SMO) reflector for your S2. Mind you, this short one is for the S2. For a S2 (no plus) you need a longer one. Also available wit the same seller: the original Convoy store.
You can get a bit more throw out of a SMO reflector, but the S2 and S2+ are not really meant to be throwers. But if you have a small emitter, like the XP-L, it’s not too bad.
