Type 0 would seem to be the best option for suppressed shooting

So I was thinking that maybe the type 0 gas block on a newer barrel with the smaller gas ports would be better for suppression. That was based off seeing original style barrels being way over gassed for type 1 gas blocks. Anyway, Bravo hooked me up and I was able to try a 12", standard gas in 5.56. The type 1 was always over gassed with a can. The type 3 was much better but depending on combination and QC, it was a little hit and miss. The type 3 300s I've shot are great but it's also a way low pressure round and even with that there's still some pretty good gas coming out of the ejection port. The type 2 is decent but still flings brass 50-60'. The type 0 setup throws 5.56 brass about 30-35', has noticeably less gas out of the ejection port and the recoil is pretty tame. Mini 10" 5.45 is also a nice shooting suppressed setup with the type 0. Tried the type 2 on a 10" mini 762x39 as well. Recoil was fine but it felt/sounded like the gun was cycling aggressively. Next plan is to try the 12.5" 6.5g with a type 2......

I think the problem is the can designs out there. With OSS and NG2 being flow through designs, I think this will be less of an issue as can design evolves.

I don't disagree but when most of the available cans work like what I tried(xcr came out in 2008? Flow through wasn't a thing) you'd think there'd be better adjustability. With that said, my tuned AR is awesome to shoot with a can but holy crap does it get dirty quick.(guessing most of that gunk is coming back through the barrel during extraction/ ejection)

I like the adjustable blocks on several rifles (my rdb continues to be a favorite with a can on) but most often the lowest setting is still too much. I've got my xcr configuration now so I'll run it until the type X comes along and/or I get a flow through can.

I can't imagine that in 10 years manufacturers will still be making sealed cans....sucks for all the NFA items that are already out there, but at least over-gassing and fouling will be less of an issue.

Of course, that's assuming that suppressors won't be banned outright in the coming years as well.
