thinking about going down to the local gun store and filling out the paperwork for a supresser and started looking at sbr's since i would already be there might as well do 2 stamps at the same time and all you have to do is register a lower or buy one there. any thoughts or reviews on the daniel defense 300 blackout pistol / sbr? was thinking about getting the mk18 upper then saw th3 ddm4 300s. my only real hesitation is weather 300 blackout is just a fad or if its going to stick around.

anyway can anyone confirm reliability on the 300s is it finiky with ammo or does it require any tuning? if i get just an upper witchever i choose im going to get the factory daniel defense buffer and spring to match so i dont have issues there.

I have an AAC upper in 300....11.5 barrel  ishoot  suppressed thru a aac 762  sdn 6, very happy...subs are really quite....super sonics still crack
