I've done my best at searching the forums, but haven't been able to piece together a sufficient answer. I recently converted one of my LMT MRP CQB carbines to 300BLK with a 10.5" barrel. I also have a 762-SDN6 that should be out of ATF jail within the coming months. My question is, what can I expect, with regards to proper functioning, when running supers and subs with and without the can if the only thing I've so far is install an H2 buffer? Should I start with a heavier buffer, different spring, anticipate the need for an adjustable gas block, etc? This will be my first experience with 300BLK, and any advice will be greatly appreciated.
Thanks,
Pete
