Just wanted to let those know who may be considering installing a TT Diamond single stage AR10 trigger into a JP LRP07 that they may experience a problem. Specifically, my bolt carrier was hitting / binding on the TT hammer. Tried two JP bolt carriers (LMOS and VLMOS) and both didn‘t two work. I contacted TT and they agreed there was a combat ability issue with my JP bolt carrier and their AR10 trigger. I know others have had a TT work in a large frame JP, so just passing this on as it may be an issue. My JP is a recent mfg. Nick-
