Hi gang...I am a bit confused with the function of my AR a the suppressor is attached. 18" wylde full length gas system and a Gem Tech "Tracker 30 can". I'm using a 1/2 x 28 adapter to get to the can. So without the can this rifle is reliable and throws brass at 4-5 o clock around 6 feet with factory american eagle and also 60gr v max handloads...all seems right here. Attach the can and now the brass is 2 o clock and about 18" to 2 feet. Its been reliable but I'm concerned why the brass is not ejected stronger. Wouldn't a can overgas the system and eject brass even further? I bought an adj low profile gas block but have not installed it. Also I expect the upper to get really dirty but it seems too much, but then I have nothing to compare to. And lastly I have a very light single stage trigger on this and it has doubled more than once with the can on...trying to get my head around this one too. Thanks in advance for some advice.
