Thanks for all the input. I was able to get an orange spring ordered and installed. Finally got to the range this past weekend, and the rifle is still choking on 3 of 10 rounds while running suppressed. Not an expert, but I think I need to slow things down a bit more. I have a standard buffer in now, but have seen comments on here and other places referencing H3 buffers, Slash buffers, etc. Anybody with a 18inch OBR (carbine stock), running a suppressor(AAC-762), care to share their secret sauce for getting my gun to run without hiccups? Worst case is I end up ordering a transquillo, and take the can out of the equation. Note: I fired 10 rounds un-suppressed before mounting the can, and produced accuracy and performance consistent with un-suppressed experience from past.
