so I’ve got a SD, the “upgrade kit” installed and am having major issues. I’ve tried the triggered company LAT and it doesn’t work. I’ve got a rare breed in a mk 18 and don’t want to swap it into the HB. also have a Atrius G-Lever laying here(HB has a geissele SSA in it) but it’s having its own problems. what are yall using for a frt in your HB and how did you get it to work for you?
