He made the point that the government profile barrel was adopted based upon erroneous assumptions and without proper engineering failure tests. He also said that top end AR makers continuing to put out rifles with government profile barrels was dumb.<\/p>\n<blockquote class=\"tr_bq\"><p>\n<i>First, I question their testing of the resistance to bending of a \u201cgovernment profile\u201d barrel.  They obviously never got real engineers involved in this problem.  The highest bending moment in a cantilever beam will be where it is pinned, which in this case will be at the receiver.  As best as I can tell, not only didn\u2019t they solve a real problem, they didn\u2019t even solve the pretend problem.<\/p>\n<p>Second, engineering resources would have performed a failure mode and effects analysis of the problem.  A failure investigation team of engineers should have been commissioned, not a military team.<\/p>\n<p>Third, if you believe the problem is that Soldiers or Marines are using their rifles to pry open boxes or crates, then teach them not to do that.  That\u2019s stupid.  I remain unimpressed with folks who try to mistreat, abuse and beat up their guns only to complain when they don\u2019t work.<\/i><\/p><\/blockquote>\n<p>It was an interesting post with good comments. You should read the whole thing.<\/p>\n<p>That led to me finding this video from last year by Ian and Karl from InRangeTV and their WWSD (What Would Stoner Do) series. In it, they test stress relieved pencil barrels from Faxon and then compare that to an original pencil-barreled Colt SP-1 doing the same test. Given I have one of those Faxon pencil barrels, I need to get my act together and finish my lightweight build using it!<\/p>\n<p><iframe loading=\"lazy\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/QTovPt4weIs\" width=\"560\"><\/iframe><\/p>\n<p>PS: Lest you think I&#8217;ve gone all &#8220;what has Wayne done now&#8221; all the time, being able to have a day without significant charges of malfeasance and self-dealing is a relief.
