The newly manufactured barrels that come with the M16A1 kits are pencil profiled and 1/9 twist.

Quoted:
Anyone making one these days? I know CMMG used to but that is a thing of the past. Would like to make a Taiwanese T-65 clone and want chrome lining with a faster twist than 1:12 to be able to shoot above 55gr. Any insight from you retro guys? 1:12 was original, and allowed the 55gn bullet to be quite lethal at short to medium ranges. In that scenario, it is probably optimal. The USMC insisted on modding the AR into a rifle that would hit at longer ranges, and had to invent the 62gn bullet to make doing so worthwhile––barely, IMHO. Depends on what you want, but if your plans allow such, why not take advantage of relatively cheap 55gn bullets? Besides, 1:12 barrels are much better candidates for a .22RF conversion kit than others with faster twists, as they tend to be a bit more accurate. Not as accurqate as a dedicated .22RF bbl, but pretty good compared to the others. Definitely useable at 25M training, if you do your job, and you use ammo that your conversion kit/barrel like. Might taake a while to settle on the ammo, but dual purpose is good, IMHO. |

GunThings, Henderson Defense and APEX are the ones I remember. I believe there are a couple more. You'll have to check to see if they're still available. Are you planning on buying one just for the barrel? If so, you may be able to find just the barrel itself in the EE or on GunBroker. Chances are, it'll be in the white, though. (It'll need parkerizing and a FSB install.)

If you know what a T-65 is, picture this: Above mentioned barrel. Magpul 20" MOE handguards (when they come out). RRA UTE upper. Sully stock with spacer to make it A1 length (T-65's had a stock that had the Sully curve in it). A1 grip. Likely an Osprey rifle length piston system as Adams Arms (more like the T-65's) can't use a standard FSB like the Osprey. It'd look *fairly* close for a clone. |

ETA: as far as I know. nobody is currently making a chrome lined 20" lightweight barrel...it's been rumored that Green Mountain barrels will be bringing one out in a few months time |

That T65 looks a bit like a 703.

just curious why the insistence on chrome lining? unless you're jungle fighting corrosion is not a problem in the U.S. from a functional standpoint, and regular stell is said to shoot more accurately for a longer period of time? Always wondered why so many people are hung up on chrome line?

Always wondered why so many people are hung up on chrome line? Because chrome lining can take more abuse like not cleaning after every range session and mag dumps. It also increases the service life of the barrel before the throat burns out. If you are building a rifle for recreational shooting you are better off with chrome lining. It also makes the bore much easier to clean than plain steel. The accuracy claims don't actually have any numbers to back it up. Its mostly based on a theory and who makes the barrel and how much care they take really determines the accuracy potential of a barrel more than what it is lined with. There were even some stainless barrels made in limited run by Noveske that were chrome lined. ETA chrome isn't necessarily JUST for corrosion protection. Chrome is harder and slicker than steel so it resists wear longer than a chromoly steel barrel would. |

There is a reason why just about all first-line military weapons since WWII (and some from WWII) have chrome lined barrels. Whether I'm in a jungle fighting for my life or just plinking at the range I want the best. It's that simple. |

I don't like to repeat the lessons learned by GIs getting killed in Vietnam. Of course all of my rifles are for HD and before retirement patrol use not just casual plinking. The only rifles I consistently had problems with in my tactical carbine course I taught was with commercail, non chrome lined barrels. They would start FTEing after just a few hundred rounds. I had to keep a cleaning rod at the ready to tap out mil spec M193 brass and a chamber brush to scrub the chamber on them on a regular basis. Go shoot 500-1000 rounds at a sitting and see just how reliable your non chrome barrel is. (we fired over 2k in our class of milspec M193 per officer) |
