sub-sonic AR15 load functioning

[Stif]

I have worked up a subsonic load for my suppressed AR in 223. My question is can anyone give advice on how to make it function reliably? It's very close but fails to fully eject the spent case way to often. Nobody likes a single shot AR.
Thanks

to go that slow i dont know if your going to get functioning. You will probably have to go with a ligher buffer spring and load the heaviest bullets that will run in your gun.

I wonder if the Oerating rod conversion might help..I know of no one who has tried the kit! Curious. Too poor to try it
