Apparently the black sticker was preventing the cart from fitting. Once removed it slid in just fine. I used needle nose pliers to screw it in until it fired. I tried to use my drip tip but it started to spin inside the cart before the cart was tight enough to fire.
Answered my own question. Maybe this will help someone else down the line. Boge LR XXL's (Dual Coil) fit The Gripper by
mad vapes but you'll have to get the stainless steel or remove the black sticker.
