16" midlength will pretty well do anything a 20" can. JMHO

I would split the difference and get an 18".

It sure would help if you told us what kind of competition and what your goals are for range use.

And, there's more to it than just barrel length.

The 18" with the rifle length gas. I've built two with that combo and the recoil is just so surprisingly smooth. Really has to be experienced....

I agree. I have an 18" CMMG carbine/rifle with the rifle length gas system that shoots great.

I'd get a 24" stainless HBAR...... JK

I'll echo what is being said and suggest a 16", or 18" if you prefer a longer length. I think you'll find more versatility at 16" over a 20", without losing a ton of velocity.
