Rated 1 out of 5 by from defective Tried a go gauge and could no get the bolt to lock up. It appears the chamber is to short. Tried a new 300 AAC round and it did the same thing, won't lock. acts just like a no go gauge

Rated 5 out of 5 by from 300 aac barrel I haven't had a chance to purchase needed parts to complete the build, but the barrel looks like it is what I expected. I am looking forward to getting the rest of parts and putting it all together.

Rated 5 out of 5 by from Great Price! Haven't used it yet. Plan to build a pistol with it. Will probably cut a couple of inches off to reduce overall length. Price was attractive enough to make the project worthwhile. Barrel arrived in good shape in short order. Hope I can find a similar deal in .223/5.56.

Rated 2 out of 5 by from Wont Extract I just got around building a upper using this barrel. I had to mortar is so hard I bent my BCM C/H. I'm going to polish the chamber and neck and see if it helps.But it shot very accurate with 125 Speer TNT's.

Rated 5 out of 5 by from best price around Function flawlesly so far. Fit and finish were great. Went together with no problem. I've only been able to shoot it @ 40 yds, but so far so good. Bergara barrels are regarded as some of the best, and I expect this one will live up to that. And at a great SG price!

Rated 5 out of 5 by from Can not go wrong for the price. I ordered one, liked it so much that I ordered another one. Great barrel and a great price.

Thank you in advance </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: NRAa</div> <div class="bvseo-answer" data-answerid="1704222"> The barrel extension of an AR-15 barrel, is the necessary component of an AR barrel that contains locking lugs. It also contains the feed ramps. The AR bolt(part of the carrier group), in the upper receiver, slides by these, twist, then is locked in place. It then unlocks when you fire.This is a 10.5&quot; barrel, this means you must possess a Short Barreled Rifle tax stamp, or build an AR &quot;pistol&quot;. AR rifles, have 16&quot; or longer barrels only. This barrel uses a &quot;pistol length&quot; gas system. Which is different from a &quot;carbine length&quot;, &quot;mid-length&quot; or a &quot;rifle length&quot; gas system.Most &quot;&quot;free-float&quot; hand guards will go over-top of a Low profile gas block, with pistol gas tube. Google those or join an AR web forum to learn more.  Lots of info out there..  <div class="bvseo-author">Answered by: Jeremy</div> <div class="bvseo-pubdate">Date published: 2015-03-23</div> </div> </div> <div class="bvseo-question-answer" data-questionid="1382357"> <h2 class="bvseo-question"> What thread pitch is on the muzzle? </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: 38 WCF</div> <div class="bvseo-answer" data-answerid="1640486"> 5/8 x 24 Muzzle Threads <div class="bvseo-author">Answered by: Customer Service</div> <div class="bvseo-pubdate">Date published: 2015-03-18</div> </div> </div> <div class="bvseo-question-answer" data-questionid="1335477"> <h2 class="bvseo-question"> Who is the manufacturer of this barrel, and what is the gas port diameter?  Thanks! </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: David</div> <div class="bvseo-answer" data-answerid="1589070"> David, I didn&apos;t think to measure the gas port before assembling, but it cycles and groups Remington 220g subs and my 220g handload subs flawlessly using std carbine buffer and spring in my pistol build. hope this helps. <div class="bvseo-author">Answered by: Mountin Du</div> <div class="bvseo-pubdate">Date published: 2015-03-14</div> </div> </div> <div class="bvseo-question-answer" data-questionid="1328692"> <h2 class="bvseo-question"> Which gas tube and hand guard size does this take?
