    Anyone know where I can get a 1-7" barrel in a 16" length for an AR-15 (with flash suppressor)? The Bushmaster and RRA sites only show a 1-9" for a 16". I'd prefer a Colt heavy barrel if possible, since that's what I'd be replacing.

    Bushmaster did a limited run earlier this year. You might call them them to see if they have any left over as they are not advertised on their website. They were only sold as HBARs. I had to send mine off to have it turned down to a M4 profile.

    Bartholomew Roberts hit the nail on the head.

    Check with Sawsales and CMMG.

    You can also look up folks such as Grant @ G&R Tactical, Wes @ MSTN, Jason @ JTAC Supply just to name a few. These fellows and their outfits carry the LMT 16" 1-7" 16" LMT barrels (M4 profiled).

    AR15.com's equipment exchange forums are also a great place to look. I thought I saw a member or two selling 16" 1-7" HBARs not too long ago.

    Thanks for the references. I'm not in a real rush to get one, but my 16" barrel is over 10 years and several thousand rounds old, so I'm going to get a new barrel eventually.

    Why is 1-9" easier to find than 1-7"?

    Well, there used to be no advantage to 1-7 unless you wanted to fire VLD rounds for long range match or needed to fire 62gr tracer.

    Then they discovered that the heavier open-tip match rounds were very effective in an anti-personnel role and the 1-7 barrel got a lot more popular. With a 1-7 barrel, you know you will be able to use the heavier 75gr and 77gr match rounds to their full potential. With the 1-9 barrel, you might get lucky but chances are good that you will get less than stellar accuracy (4-5MOA) with the heavier rounds.

    1/9 twist is the standard twist in the AR-15, it is considered the all around twist.
