I am having some issues with a new 6.5 creed build.I'll start with parts,Wilson Combat 24" barrel,.080 gas port,Toolcraft 6.5 double ejector small pin BCG,billet upper and lower,SLR adjustable .836 gas block,15.5" gas tube,rifle length buffer tube,9 11/16 depth,5.4 oz,5.303 length buffer,initial 12 1/2" .078 wire spring,Triggertech Diamond. Initially test fired with AR15 rifle length gas tube,wouldn't cycle,had to run gas block open,also mangled a few rounds feeding,single loaded from there,very accurate.Did some research on this site,found post on extended gas tube.Installed 15.5 tube tonight and re-tested.Was loading 4 rounds at a time,chambers 1st round ok,will fire then either fire or fail to chamber ,the 2nd or 3rd rounds,then the 4th feeds and fires ok??repeated several times?Initial gas block was 7 clicks out,ended up open,the bolt locks back after last round,and is locking on bolt face not carrier.BCG seems to slide into battery fairly easy and smooth (with upper open by hand)Headspace seems ok (I don't have .308 gauges),spent case heads show no damage,primer strike looks good,mild scratching on case wall,ejects all brass in 3ft circle,140 gr S&B (only thing local shop had,other ammo on order) was used in testing,several P-mags tested,same issue.I do have a 12 3/4".078 wire spring to try,but wanted to test the longer tube first.I have built over a dozen AR15's,of various calibers without issues,but the 6.5 obviously is a different animal?? I know I am the king of the run-on sentence,but wanted to give as much info as possible,any help would be appreciated.
