20” ar15 barrel gas system length

What is the length of the gas system for the 20” barrel that you offer?
I’m assuming rifle but want to confirm.

Curious to see what type of groupings you get with this barrel. Not a big fan of the gas block profile .750 would be better or the twist rate 1:12, 1:7 or 1:8 would be preferable. Chrome lining is kind of nice. Cant really go wrong with $99, but I guess you get what you pay for.

I would have to be rifle length, mid-length would not reach.

There’s a guy in the black rifle section that was signing it praises.

Just bought one and got the gas block. Mid length did not fit. Rifle length fit.
