16 inch ar15 platform............
Having that same thought myself.. here's where I'm at..
16" - plentiful, easy to find.. however typically comes with carbine gas system (short sight radius, "overdrives" the bolt carrier making it a harsher operating rifle. With a mid length gas system, the dwell time (gas block to barrel end) is better and the recoil\bolt action much smoother
18" - fluted barrel with mid length gas system would be perfect, or adjustable gas port and rifle gas system.. longer sight radius. 18" is what Robbie Johnson, Daniel Horner, Jerry Mikulek run.. allows hand to be placed further down the rifle allowing you to "drive" the muzzle better..

If you expect to be a contender you need to run optics anyway.

Yes, 18 is the shortest barrel for a rifle gas system, but it leaves only 5.5" between the port and the end of the barrel, and some ammunition may not cycle correctly (short stroke) A 20" barrel with rifle length gas system, a 16" barrel with mid-length gas system, and a 14.5" barrel with carbine length gas system all have the same amount of dwell time (distance from the gas hole to the end of the barrel). That "typical" length is 7.5, "but" certainly with an adjustable gas block you'll have no problem..
I think he was referring to your skill level.

Swing and a miss.
Optics and irons almost never compete together...so you don't need to upgrade from irons to optics to be competitive.
....and even then it doesn't always matter.
There are guys shooting heavy metal irons than can out do open shooters.
As far as gear goes... People gotta stop putting the cart before the horse and decide what division they want shoot in and THEN gear up accordingly.
Had a few guys show up thinking they were in one division only to get bumped into open because... They bought without reading the rules.
I'm not savvy to rifle stuff, what's Dwell time ?
