Preferred general purpose rifle - barrel length & gas system
Over the last year, I've learned quite a lot about the AR platform as a whole from when I first bought my mutt rifle. After deciding that I wanted to make a general purpose rifle, I couldn't figure out which of the two popular carbine barrel lengths I wanted, nor which gas system should accompany it. I sat down and poured over the various 14.5" vs 16" barrel and "what's your favorite gas system" threads, but none of them really had any direction for the discussions; a middy 16" might be nice for a competition gun, but for home defense a 14.5" w/ carbine gas system might be preferable if an SBR isn't available. Short and sweet of it is, I haven't found any topics that tied together barrel length and gas system based on how the rifle would be used.
This prompted me to post this poll in an effort to compile all of the scattered information comparing barrel lengths and gas systems into a single, coherent topic: given the options presented, what is your preferred barrel length and gas system for a general-purpose, jack-of-all-trades rifle? Feel free to share your reasoning, too!
*As a side note, I'm not looking for advice on a new build. This poll is purely to gather info on folks' preferences for barrel length & gas system on 'general-purpose' rifles.
