Does anyone have a fix for the BCG not cycling all the way to the rear in SS mode? I shaved the upper shelf down to make space for the lever to slide back fully and it cycles perfectly in the semi position, but when I put it in the SS position, the bolt gets stuck about 3/4 of the way back and I can clearly see the lever is not making its full rotation. I’ve also sanded some material off the top of the lever and it still won’t function in SS mode. All insight and feedback will help, Thanks.
