BT TM-7
The BT TM-7 was a .68-calibre electropneumatic paintball marker introduced by BT Paintball in 2008. It adapted the operating system of the Invert Mini for a scenario marker styled after the Heckler & Koch MP7. Paintball-Online published a hands-on account in July 2008, and the original BT manual carries a 2008 copyright.[1][2]
Design
[edit]The TM-7 used compressed air and a regulator integrated with the cylinder mount. Gas passed through the grip frame without an external hose. A 9-volt battery powered the electronics, and a ball detection system monitored the breech. The body had a retractable stock, a folding front grip and accessory rails. An offset sliding feed elbow could be moved to expose the breech.[1][2]
The original configuration had an external selector with safe, semi-automatic, PSP burst and NXL automatic settings. The owner's manual also documents electronic adjustment of the firing settings.[1][2]
