I finally got around to testing out my other carrier in my 6 ARC this morning.

I made a couple of observations. I figured it was worth following up on as it was mentioned before by others in the thread.

1. No gas really to speak of gets in the trigger. At least not any more than normal, actually maybe a little bit less. Magazine yes, trigger not so much.

If you look at the left side of the carrier there are relief cuts as well as a pocket for gas expansion.

Usually energy will go through the path of least resistance. On a traditional BCG the back pressure gas just goes where it goes. With this though it has a large enough channel and relief cuts on the side to direct gas in a certain direction.

I have not measured it specifically, but that initial gas gets directed down towards the magazine through generous relief cuts in the side of the carrier. After the initial gas puff it has a couple of inches of rearward travel (with the ejection port open) before it gets to the trigger.

At this point I'm tempted to say you could have a lot LESS crap in your trigger with one of these vs the traditional carrier. It really just depends on how effective you think those relief cuts (and pocket) would be at changing the direction of that gas.

2. With the longer gas system in today's test it was really nice to shoot. With no hearing protection there was zero discomfort at all. They claim a reduction of 10DB for the shooter's right ear (with that gas length), and I believe it for sure.
