10/22's are junk. marlin model 60 is best.

@juggnautbitch and thanks for sharing your opinion.

The following is from the Shilen website under FAQ. Shilen is known to make quality barrels. Whether they are the better than Hart, Krieger, Douglas is debatable. Whether you agree with the information posted bellow or not, here is at lleast a little info from one makers point of view.

Fluting is a service we neither offer nor recommend. If you have a Shilen barrel fluted, the warranty is void. Fluting a barrel can induce unrecoverable stresses that will encourage warping when heated and can also swell the bore dimensions, causing loose spots in the bore. A solid (un-fluted) barrel is more rigid than a fluted barrel of equal diameter. A fluted barrel is more rigid than a solid barrel of equal weight

[John4566442]

All rifle barrels flex when fired. Accuracy requires that they simply flex the same and return the same each time they are fired, hence the requirement for a pillar bedded action and free floating barrel. The unrecoverable stresses that fluting can induce will cause the barrel to flex differently or not return from the flexing without cooling down a major amount.

This is usually longer than a shooter has to wait for the next shot. The claim of the flutes helping to wick heat away faster is true, but the benefit of the flutes is not recognizable in this regard until the barrel is already too hot. –Shilen barrels

@John4566442 but by fluting you are also increasing surface area, this will allow more heat from the surface to dissipate. so perhaps what you lose in mass you gain in surface area, then fluting is the same as not fluting. lol i dunno just thinking out loud

[John4566442]

@AGStewart I've always thought that the idea of increasing cooling by fluting was bs. My reasoning is that by fluting, you reduce barrel mass. The less mass (steel) the LESS it will disapate heat. Old air cooled machineguns used fins on their barrels to add mass and external surface area. Flutes reduce it. Just my 2 cents. I think fluted barrels look cool, regardless.

@nerdymechanic

well not so much the process of fluting. what I'm talking about is heating up during extended firing. if the flutes are not equally deep in proportion to the center of the barrel...the deeper flute will be the weakest point. to where the heat will tend to gather faster...which will warp the barrel? I have a stainless steel barrel I think I want fluted. this is for my 5.56 ar.

[nerdymechanic]

@clap5 It could. but that is why so much fluid is being used, to help reduce the risk. Also depends on what the barrel is made from.

Someone told me you can not flute a finished barrel because it will heat it up and warp the barrel. Is that true?

Nylon 66 oh yea
