so, i caught the short barreled 300blk bug and i just cant shake it. its so bad that i have no other option but to run a suppressor so that its not so painful on my ears! all subsonic data or info i can find is atleast a couple years old and i am having a hard time finding out what people are perscribing their subsonic rounds on the reloading bench. ive heard 1680 is the ticket to reliable subsonic cycling in an AR type rifle but as hard as it is to come by i am curious as to what else will work??

10" barrel
Pistol Gas
M16 carrier
Carbine buffer for now

for all of you with this same or similar bug...cheers!

That is a two piece that I make in my shop it is made to go over the bowers can to add some protection to it and you can mount the front sight out further forward for a longer sight radius
