TAC 9 SS update OOB

Tac 9 SS release is more than likely going to be delayed, took it out for testing had a case head separation and OOB that ended up doing the frame in. Yes I checked the chamber after the case head separation it was completely clear, not sure what caused this. The timing on the trip is correct it won’t drop the hammer till the bolts fully in battery. Most of the testing was done on a PLA Pro frame the is the first test done on the pa6-CF one. Ammo was Privi partisan never had an issue before, not sure if it’s possibly related to the feeding issues I’ve been having seems like no matter what mag I give it this things never wants to feed consistently. Anyways what’s the best way to contact BLC?
