Sniper Country Duty Roster collective wisdom


Selecting a new barrel:


I'm looking to build an AR15 Service Rifle and want the most BBL for the least money. LOL. I have heard about Kreiger and Obermeyer. I have heard good things about Armalite, but the much lower cost leads me to believe Armalite bbl's are not the same quality. Has anyone else had good or bad with the Armalite AR15 bbl's. Does anyone know why the use Wilson bbl's for 15's instead of the Rock bbl's they use for AR10T's.

Mike M.: Armalite's rifles and barrels are very good. I believe that Armalite switched to another rifle manufacturer because of supply issues, the quality of the barrel remains the same.

Mike: I can not speak for Armalite but if you purchase the right barrel from them I am sure it will perform. Another viable choice is one of the Olympic Arms match barrels. These are particularly nice for a competition rifle as they are NOT chrome lined and are moderately affordable. I would recommend against a chrome lined bore for maximum accuracy. Go to their website and read about the options. You can get both broach and button cut rifling. I chose the lesser expensive of the two and it performs extremely well for under or right around $200.

I'm working on an M1A project, and I'm just learning about barrels. I'll probably go with a Krieger heavy match barrel, but can someone tell me how the Barnett / Douglas, Hart, Shilen, and other barrels compare? If I'm only going to be shooting 168-gr or 173-gr bullets, which rifling twist should I get? What about 4 groove vs. 6 groove?

Bach,

If you're just starting out get the Douglas bbl. Champion's Choice sells them INSTALLED for $200. The Krieger MAY be a LITTLE better, but unless you're a High-Master class shooter you probably wouldn't notice the difference. If 168's is all you'll shoot a 6 groove/12 twist is fine, but if you may want to shoot 173's get a 4 groove/10 twist. The military even uses these bbls in some of their match M-14. The AF put one on mine, and 2,000 rounds later it still holds a tight X-ring at 600 yards (providing I have my own fecal matter coagulated!)

As an aside.

Krieger barrels are not perfect.

My first Krieger AR-15 barrel was purchased as semi-blank about 7 or 8 years ago. Krieger turned the large end to .950" and the small end to .750". No tapers were involved just two cylindrical sections. When this barrel was spun in the lathe it was obvious that it was not turned in one setup. The two cylindrical sections were not concentric with one another, but about .030" out. I stood back and rubbed my chin for awhile. How could this happen. I wouldn't mind a couple of thousandths and could understand that. But not this much. Something must have been wrong with his chuck. I went ahead and chambered it and it has provided great service for many years with no unusual properties. I don't remember which end was not concentric with the inner bore, but this is a case of metal not being in equal thickness all the way around the inner bore. One side of the barrel will heat up quicker than the other, but one would be hard pressed to actually prove anything on target. Too many other variables. One thousand yard benchresters have experimented with sleeving the entire barrel with a tube to keep a cool breeze from causing uneven heating (or cooling) of the barrels. Don't really know what is in vogue in that sport; just what I read.

Back in about 1978 or so I bought a new Remington 40-XC repeater barreled action (.308) . There is a long story about how I eventually got this animal to shoot correctly, but we'll save it for another day. Anyhow, eventually I wanted to turn the last 2 inches of the barrel to .850" to fit a barrel band and recrown it. It soon became obvious that the outside of the barrel was not concentric with the inner bore either. These barrels are not turned, ground, or finished on "centers" (as they should be). Maybe this is all changed so don't hold me to it. I'm just stating what I saw on my particular barrels.

Does all this make a difference? Theoretically it does. A barrel that is hotter on one side will behave like a bi-metal thermometer. It could direct shots high, low, or any direction. Not a good situation that is for sure. Although we are dealing with miniscule amounts of movement the error is amplified by great distances.

Also, after shooting a string of shots (in a conventional rifle) a barrel will not cool evenly. The underside will be hot for a longer period of time compared to the top. Free floated barrels should have a generous amount of space around them. We want them to "breathe". Beauty is as beauty does.

All this is just "food for thought". Dig in.

Barrels. I have a choice between a Lilja or Schnider barrel to finish up my .300 Win Mag project. Which would be the best choice? I also have decided to stick with the 190 gr. match load so I probably want to use a barrel with a one in ten twist...correct? I do not plan to shoot a lot of other weight bullets.

Cory,
You can't go wrong with either one. I have both and both are top quality barrels. I would probably go with a Schneider for no other reason than that he seems to have a harder barrel and they last longer. This would be my only reason esp. with the 300wm. Stay with the 1 in 10 twist it will work great with the 190s. If you go with a Schneider don't be surprised if it takes longer to break in, mine did.

Roy,

According to Corey of Olympic Arms there are now two Wilsons making barrels. Not sure if either one is of handgun fame. The Wilson that I'm aware of that supplies some of the barrels to Armalite makes a decent product. But it is not a "match grade" as we have come to know and expect. I know they used to supply Ruger with all their barrels too. Anyhow, Corey said that another Wilson is making junk AR-15 barrels. Beware.

If you are going to "upgrade" go to a reliable supplier for your upper. Your chances are much much greater of winding up with a usable product. Armalite, Olympic, Colt, and Bushmaster all come to mind. They all have websites too. Do a little searching. Let them supply a bolt and carrier too.
