I'm getting into competition shooting. I'm in the process of building my own AR-15 in .223. I will be shooting up to 400 yards. Which size barrel would be the best; 14, 16, 18, 20, 22 or 24 inch? Also, get a heavy or light barrel? Any recommened scopes? Anyone who can help, please do so.

What types of competition do you want to participate in?

Both the Wilson and Douglas match barrels have good reputations for quality and accuracy at a reasonable price. Kriegers are more expensive, but are renown for their durability - so they're often a good value for high-volume shooters.

20" is typical for precision shooting at longer ranges, but you might want something shorter for action oriented disciplines.

Look at White Oak. They advertise themselves as a match rifle builder, with tactical/hunting on the side.


I've got one of their 6.8 barrels and I've been very pleased.

will you be shooting primarily at 400yds or greater?

do you plan on shooting 'service rifle' style competition?

if so, 20", 1:7 or at least a 1:8 twist rate...

Wilson from WOA/WOP with proper front sight base (FSB) will set you back about $250. they are stainless...

you can go with a Douglas; you will get very similar results for about the same money...

if you go Krieger you will be able to say youve got a Krieger barrel and to be honest you probably wont be able to tell the difference in accuarcy. you MAY be able to detect a difference in longevity. barrel life depends on many variables so you cant make a blanket judgment that a K-brand barrel will automatically last longer than another...

if youre using it for run-and-gun competition, you can save some valuable weight by going with a Chrome-Moly barrel vs stainless. with very similar life span...

in MY experience CM barrels start losing accuracy from round one and gradually decreases to the point its noticeable beyond 300-400 yds. stainless will hold its accuracy up to a point at which it will just stop shooting well at the longer distances. think of them as alkaline batteries vs lithium...

give us a bit more information on what your intentions are...
