I bought a RRA light weight chrome lined 16" barrel for my "ultimate carbine" build a few years ago.
Never any issues with it. It is free floated, too. For what it's worth, I've never shot more than 100 rounds through it in one range session. I've usually got a couple other rifles and a few pistols to shoot, too, so I don't just shoot one gun all morning/afternoon. |

the rifle was designed from the ground up to be lightweight
once the bugs were worked out, the M16 worked well in Vietnam combat My SHTF carbine has a LW Daniel Defence barrel It works fine. . |

Nothing is wrong with them OP...just don't expect an MG barrel. I have an SP1 with a slim barrel profile which kicks ass and my HD rifle is rocking a 16" DD pencil profile barrel which it's had for about 8 years. Both shoot fine I just don't intend to do mag dumps with them or spend an hour putting 4000 rounds down range (yes I'm exaggerating but hopefully you know what I mean).

So on a 3-day, 2,000rnd carbine class it should be fine maintaining its POA/POI?

I'm a huge fan of lightweight barrels. The trade is they don't always hold POI as well and they are slightly less accurate. Get a carbine that holds 1.5-2 minutes radius from POA whether hot or cold, suppressed or unsuppressed and you're good. With a light barrel that means you will usually want a higher quality barrel to do the same thing a cheaper heavy barrel will do.

One other thing to consider is a new lightweight profle, such as the BA Hanson profile and BCM ELW profile. These profiles minimize the downsides to using lightweight barrels, especially POA/POI shift as they heat up. They also tend to do fairly well with suppressors, compared to other pencil profiles and even gov profiles.

Cook offs in large amounts of FA shooting. CD said he had one once with a govt' profile M4... I think it was.
Otherwise for most of us, probably nothing. I've had two LW barrels and one was really accurate and the other was acceptable, but shifted POI from round to round more than I liked. So does my Govt' 20"er. My HBARs don't shift POI barely at all and are accurate. But too heavy.

It's all trades.
But you have to use an M4 hard to get a cook off. FWIW light barrels cool faster too. |

Thickness of the barrel walls is the main turnoff for me. But for somebody who isnt doing fudd mag dumps into dirt, it's going to be a non issue. Sometimes MILSPEC goes full fudd, so I gotta have that SOCOM profile.

everyone should be forced to run a 20" HBAR in these classes the first time. then they won't complaint about anything, ever again.
plenty of skinny barrels in expensive rifles. the FN FNC, FN SCAR, FN FAL...lots of FN stuff there. i see no reason for heavy barrels for carbines. |

I bet it's more accurate then any of the govt' profiles you had, eh? Personally I think a .750 all the way is probably a good compromise, but very few people make a barrel like that. Well, that I know of. But so many people make barrels now. Quote HistoryQuoted:

so here's a question;
what factors contribute MOST to barrel whip? overall profile? profile at the muzzle? metal used? barrel length? |

Nothing is wrong with lightweight barrels if they are done right. Faxon seems to be doing them right. Their Gunner has become my favorite barrel. It's government profile in back without all the useless weight in the front. I don't abuse my rifles, and I'm not into mag dumps, but so far the Faxon has done everything my heavy barrel has done, minus the boat anchor.

It baffles me about all the talk about weight. 99% of us are not on patrol 12 hours a day. I would carry a few more ounces using a standard or heavy barrel. Accuracy is high on my CTQ list.

For a rifle intended to be carried around alot I really like the pencil profile. It is less weight and also balances much better that an M4 or HBAR profile. The issued M16A4 I had at my first unit was horribly front heavy with the barrel profile combined with the quadrail. The M4 I got later on wasn't much better. Granted quadrails are old tech now but still its .625 for me unless i'm building a rifle intended to be fired off a bipod.

I have one lightweight carbine I have just because it's ultra light and easy to pack around. It's stayed accurate and does it's job well. I also don't bumpfire it. I have barrel in the garage that is a lightweight and it was bumpfired till the handguards melted and gas tube was glowing. One of the WAHTF members fried it and I've been meaning to put it back on a upper and use it as a truck gun build. Just need an A2 upper receiver to go with it.

I have had a 4150 pencil barrel from Bushmaster for over 5 years now. Out of my other two 1/9's, it's the most accurate and match ammo will give you nearly moa. Nothing wrong with saving weight, but I also prefer my government medium contours and 1/7s.

No I did not. Every issued weapon I had I stripped off everything I could. No accessories other than sling and optic. I never was required to have a PEQ-15. Although still being poorly balanced, my M4 was kinda cool. it had a 5 digit grey lower with N stock and a newer black upper. |

The lightest profile I own is a Faxon 14.5 midlength pencil. As far as I know, it's about the absolute lightest profile available and its THIN. Like .550 most of its length except the .625 gas block journal. Much thinner than a standard lightweight profile. Its ridiculously lightweight, but it heats up very quickly and POI does shift. I really don't mind the shift, though. For it's use, the 1 moa impact shift means absolutely nothing. Also cools down much faster than my SOCOM profile 14.5.

It depends on what kind of accuracy and what kind of distances you're talking about. I have a 2 Faxon Gunner barrels but I haven't ran them enough to test precision when hot. But my ballistic advantage light .750 barrel does very well at a range of temperatures and it's really not heavy at all.
