Heavy barrels are for machine guns and bench-rest shooters. |

I am sold on the so called medium profile barrels. I am having a 16" Bush H-bar cut down to 14.5" with a permanent flash suppresser and having it turned down to 0.850" under the handguards. The M4 is 0.640" under the handguards and the H-Bar barrel is 0.98"-1.02". I figure splitting the difference still gives you enough mass to handle the heat and takes off enough to make it nicer to carry. I had an 18" match barrel turned down this way and it is a lot nicer to carry in the field but did not loose any of it's accuracy. It does not shift POI like some of my thinner barreled rifles do when they get warm. Just my $0.02.

I figure that with my SIR I can get away with the thinner profile. It would suck BAD to have it tapered down, then figure that it's too thin. Thanks for the reply .... Chris |

I had my 16" Hbar turned to .75" all the way to the chamber. There was no noticable loss of accuracy anf no noticable heating problems.
BTW if you are worried about weight there are many ff rails out there lighter than the SIR. I use a Daniel Deffense ff rail. It only weighs a couple of onces more than the parts it replaces. |

I wouldn't say I'm "worried" about the weight. I exercise on company-time five days a week, and one day on the weekend, so I'm physically fit enough to handle the weight. But if my M4 can put rounds downrange without the extra barrel width, then the HBAR is going to get thinned down! Chris |

The length of my 20" HBAR doesn't bother me too much. Outside of making it lighter, what other effects would fluting have?

It's suposed to give you greater cooling capacity by increasing the area of the outside of the barrel. Then there is always the "coolness" factor of having an AR that is different than everyone elses. Personally, I'd spend my money on ammo and mags.

Get that bad boy fluted.
1. Lighter 2. Faster cooling due to more surface area 3. Looks 4. Accuracy (according to bushmaster) 5. B/C I said so! [smoke] |

It appears the jury is back with a verdict...fluting, it is. Does Kurt's flute the whole barrel? Under the handguards, etc.?

Just another thing besides heat to consider that I didn't see anybody mention, a lighter barrel will have more muzzle rise between shots than a heavier barrel withe same type of muzzle device.
If you are running iron sights or a red dot, you may not notice it much; but if you are running an ACOG where the jump is magnified 3.5x or 4x then you notice it more. |

I'ld have to go with either fluting or what ID hunt said.
.85in is really thick enough. Even .75 (but not .625 that gov't profile is just way too light under the handguards unless your use is limited to less than 90 rounds at a time. Removeing .13-.23in from the outside will have a dramatic effect on weight. The most weight difference comes from removing metal from the outside of a circular metal part. Maybe you could taper it under handguards and flute forward of the gas block. [b]I like to keep weight to a minimum as I want to buy a heavy 20-24oz sound suppressor and dont want the gun to be overly heavy I just fluted my 16in Dissipator meaning the barrel and suppressor will way approx 65.6oz or 4.1 lbs that's getting heavy. essspecially with most of the weight out front[/b] |
