Off the cuff logic!!!
It seems to me if the barrel is not the same size from chamber to muzzle or taper toward the muzzle it would affect the accuracy of the weapon. Alot of ARs have smaller diameter under the handle guard that gets larger toward the muzzle. What keeps these from warping and causing trouble when fired mutipul times? |

What keeps these from warping and causing trouble when fired mutipul times? Strength of the steel. Though if you fire enough the barrel will droop and a bullet will exit the side of the barrel. There was a test of this phenomena the Army did a few years back and was posted here |

Alot of ARs have smaller diameter under the handle guard that gets larger toward the muzzle. What keeps these from warping and causing trouble when fired mutipul times? It is more dependent on the quality of the barrel fabrication than on size/diameter/taper, and by quality of barrel fabrication I mean the quality of the barrel steel, the straightness of the drilling, quality of land/groove forming whether cut, button, or hammer forged. The smaller diameter under the hand guards does not actually affect accuracy (precision I believe is what you're really referring to i.e., the ability to shoot good groups such as sub-MOA). A quality fabricated barrel properly stress relieved will not warp and cause group dispersion as it heats (unless overheated to extreme, in which case, as the above reply notes, any barrel will droop at some point of extreme over heating/extreme round count of continuous full auto fire). |
