Armaspec hates you - Armaspec C Sound Mitigation Gen3 Buffer

The buffer prevents last shot hold open, so it literally doesn’t work. I have tried it in 4 different rifles and when it’s installed, the bolt doesn’t hold open. I have attempted to contact Armaspec two different times over the course of three months. Each time they acknowledge the request saying not to bother them again as it will slow down their response. Since they obviously don’t intend to respond, I think they say that so they have time to delete emails before their inbox fills up. Any company that hates their customers this much doesn’t need any new customers.
