=== Expansion of the product range ===

During the late 2000s, BT expanded beyond conventional mechanical blowback markers.

The company developed the BT Electronic Grip Frame, allowing compatible mechanical markers to operate using electronically controlled firing modes.

The [[BT Rip Clip]] loader was also introduced as a side-mounted, motorised feeding system.

In December 2007, contemporary retailer reporting documented the BT-4 ERC, which combined the BT-4 Combat platform with an electronic trigger frame, Rip Clip loader and Apex barrel system.[6]

The company also introduced additional tactical-style marker configurations, including the Delta Elite.
