Default Question on mid-length AR15 for Service Rifle

The 2018 rules in section 4.1.1.c read:

" .... carbine length gas systems may be used for barrels less than 20 inches. "

I'm building up a rifle for local 100 and 200 yard matches. For reasons of weight (long story) I want to use a 16 inch barrel and shorter rails. If I get to the point where I have the ability and opportunity to shoot longer ranges I will be building up a 20 inch upper.

My question is for a 16 inch barrel can I use a mid-length gas system or do I have to drop down to carbine length?

TIA. Appreciate reference to thread if this has been asked and answered before.

The think the important word here is "MAY", implying a choice on your part.

Legal, but the sling has to be mounted at carbine length - 8" +/- 0.5" from the front of the mag well.
