Tiberius Arms' Open Dot scope is all about performance, with a price that won't break the bank. Fits on all standard Weaver or Picatinny rails - you can mount it directly on top of your marker (like the Tippmann X7, Platinum Series Tippmann 98, BT TM-7, Smart Parts SP1, and many more), or you can outfit your gun with a carry handle or elevated sight rail to gain a better profile of your intended target.
