The BT TM-7 utilizes Mini Technology to inflict maximum force from a marker of minimal size. Donít be fooled by the size of the TM-7ís exterior; it can hang with the big boys and is by no means a lightweight. Once you hold one and pull the trigger, you wonít want to put it down. Its lightweight, yet durable construction is perfect for close quarters or long-range combat. This is the marker that just may have people rethink the way they looked at Mil-Sim paintball markers.
