ar15 barrel selection

many of us will want to build or have an ar15 built to match our envisioned needs ,
the less expensive AR15 rifles you see on sale typically have thin light pencil weight barrels that make the guns light and handy and easy to carry,
and while thats great its not always the best option,
especially if your on a strict budget and want the carbine or rifle to last many years.
if your a navy seal you may have access too near unlimited ammo,
be required to provide cover fire to keep some aggressors head down while you vacate the area and you may like the light carbine weight,
thats fine when you have an armorer that will gladly swap out your carbines barrel if asked,
But for the average military style semi-auto clone, rifle owner,
I would tend to disagree, that for most guys a heavy barrel makes little sense
, a larger heavier stainless fluted barrel with its far greater surface area
, and larger diam. is stiffer and dissipates heat faster.
yes it weights a few extra lbs, but most of use are not carrying heavy packs,
and dozens of extra mags of ammo.
most of us will never dump mag after full mag on full auto ,
most of us will expend the vast majority of our ammo selecting a target and squeezing off a shot,
seeing the result and maybe change target or aim point,
for that a heavy fluted barrel tends to have increased accuracy and better heat distribution.
yes I'm all too well aware most guys can,t hit crap from field positions,
and spend a great deal of time shooting off a rest or sand bags ,
and rarely at ranges of over 200 yards, so the minor difference in potential accuracy is not something they will notice until their personal skills improve.
if you want too do, frequent rapid fire semi-auto to simulate full auto mag dumps,
you'll be lucky if your barrel lasts (accuracy) more than 2000 rounds
,
shoot at a reasonable rate, allow the barrel too cool between magazines,
and especially if you select a heavy stainless fluted barrel, and you'll more than quadruple that expected bore life.

I personally like bull barrels 18" with 1:8 twist...
Or 14.5" with a welded 1.5" flash hider carbine barrels with 1:7 twist...
 
If you still don't think this is real, then consider this:
All the guns that hold all the world records for accuracy have heavy profile barrels.

All competitors in Bench Rest competition use rifles with heavy profile barrels.

All competitors in F Class shooting use rifles with heavy profile barrels.

Virtually all current issue sniping rifles use heavy profile barrels.
