<!--begin-bvseo-questions--> <!--begin-questions--> <div id="bvseo-questionsSection"> <div class="bvseo-question-answer" data-questionid="1328721"> <h2 class="bvseo-question"> I own a DPMS AR-15 and are looking at the CMMG .300 AAC Blackout Carbine size it said you can change the barrels but do the gas block or pipe need to be change also? How about the clips ? Thanks </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: brucestitan08</div> <div class="bvseo-answer" data-answerid="1587666"> If your DPMS is carbine length all should be transferable however it would be best to start a new barrel with a new gas block and gas tube. Part of the beauty of the 300BLK is that the only necessary change is the barrel. BCG, bolt, magazines, lowers all can remain the same. <div class="bvseo-author">Answered by: Dond</div> <div class="bvseo-pubdate">Date published: 2015-03-04</div> </div> </div> </div> <script type="text/javascript"> if (document.getElementById('bvseo-questionsSection')) { document.getElementById('bvseo-questionsSection').style.display = 'none'; } </script> <!--end-questions--><ul id="BVSEO_meta" style="display:none!important"> <li data-bvseo="bvDateModified">2015-03-04T22:05CST</li> <li data-bvseo="ps">bvseo_cps, prod_bvqa, vn_cps_3.1.1</li> <li data-bvseo="cp">cp_1, bvpage1</li> <li data-bvseo="co">co_hasquestionsanswers, tq_1</li> <li data-bvseo="cf">loc_en_US, sid_218195, PRD, sort_recentAnswersFirst</li> <li data-bvseo="diagnostics">clientName_sportmansguide</li></ul><!--end-bvseo-questions--><!--BVSEO|dz:Main_Site-en_US|sdk:v1.0.7.0-n|msg:timer 31ms -->
