Editing BT-4 ERC

The '''BT-4 ERC''' was a factory configuration of the [[BT-4|BT-4 Combat]] sold by [[BT Paintball]]. It combined the .68-calibre blowback marker with an electronic grip frame, a side-mounted Rip Clip loader and an Apex barrel. Retailer Paintball-Online reported the package back in stock on 6 December 2007.[1][2]

The electronic grip provided semi-automatic and selectable burst and automatic modes. The Rip Clip used a sound-activated motor to feed paintballs from the side of the receiver. The Apex barrel used an adjustable muzzle attachment to apply spin to the paintball. Empire's later BT-4 series manual includes an ERC parts diagram and separate diagrams for its electronic grip and Rip Clip.[1][2]
