My most accurate 16 inch barrel has a carbine length gas system also. It responded very, very well to this
Tubbs Spring
I put a JP clamp on style adjustable gas block on it also. It shoots very smooth. You don't even blink after it is fired.
I had another carbine that i solely shot with only the Tubbs spring and nothing else. That worked satisfactory. If you are on a budget that is a good option.
Another option is to get a Bootleg or Gemtech adjustable Bolt Carrier Group. Don't mix that type of BCG with with the strong Tubbs type springs though. Go back to a regular buffer spring.
For a hunting gun i like my adjustable gas block. I have it tuned all the way back so it will barely lock the bolt back on an empty magazine. The problem with this is that it will not cycle at all unsuppressed. That is fine with me as it is a hunting gun only. And i will never shoot it unsuppressed again.
I have a Bootleg BCG and that is a very good option for rifles that you want to go back and forth with as it adjusts very easily. You do need a screw driver though... The Gemtech version does not require any tools.
You can get a more simple type adjustable gas block that can be operated easily for changing from suppressed to unsuppressed. The problem with those is you need a shorter hand guard than i like.
Which brings up another problem. Hand-guard selection and gas block clearance.
You have to think of an adjustable gas block as a disposable item. They just can't last for ever. To have moving parts in that type of environment is good engineering.
For a fighting rifle i recommend a pinned gas block and a mid length gas system on either a 14.5 or 16 inch barrel. Or a rifle length gas system with an 18 inch or 20 inch barrel.
The pinned 14.5 inch barrels are a nice way to go as you normally need to use Rockset or some like material to ensure your flash hider/break does not come loose. A pinned and welded attachment guarantees that.
I have a 14.5 inch mid length that shoots suppressed very smooth. No other modifications.
You will find different powders have less gas than others. AR-Comp has noticeably less of a gas kick than some others.
I think differences in suppressor brands can also make large differences. My surefire can shoot a carbine/carbine system very comfortably with only a Tubbs spring and AR-Comp powder.
