planeflyer21 Posted October 21, 2014 Report Share Posted October 21, 2014 Brand new rifle? How many rounds through it? Are you using enough lube to supply a hookers' convention in Vegas? Quote Link to comment Share on other sites More sharing options...
Big BS Posted October 21, 2014 Author Report Share Posted October 21, 2014 Yes new rifle using lots of lube I took rifle apart no big burs or hang up that I can feel or see noticed a lot of powder by the gas block all over the barrel do you think it could be a misaligned gas block Quote Link to comment Share on other sites More sharing options...
Big BS Posted October 21, 2014 Author Report Share Posted October 21, 2014 About 100 rounds so far Quote Link to comment Share on other sites More sharing options...
blue109 Posted October 21, 2014 Report Share Posted October 21, 2014 (edited) did a quick google search...those things have a worse reputation than CMMG and POF combined! do the ejector and extractor have good spring tension? is it hard to seat a round flat against the bolt face by hand?

Robocop1051 Posted October 21, 2014 Report Share Posted October 21, 2014 It's a BlackThorn... No bueno. Not necessarily bad parts, just bad builders. You may have your work cut out for you. Id strip the bolt and check it all out thoroughly. Springs and extractor specifically. Does the BCG hold back after the last shot? How does the gas system look?

98Z5V Posted October 21, 2014 Report Share Posted October 21, 2014 OP, cut your losses and just sell it on the local CraigsList or local Backpage. Dump it and move on to something else. Nobody here can possibly diagnose the amount of $hit you're going to go through with that contraption. Research below - click that and read up. https://www.google.com/search?q=Blackthorn+Vulcan+Hesse&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=nts Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted October 21, 2014 Report Share Posted October 21, 2014 BlackThorn rifles are notorious for needing complete and very expensive overhauls. Sometimes people get lucky... sometimes. Quote Link to comment Share on other sites More sharing options...

98Z5V Posted October 21, 2014 Report Share Posted October 21, 2014 (edited) Here's a Blackthorne rifle for ya, OP - first shot ever from this rifle. Watch the vid. http://www.liveleak.com/view?i=963_1392257627 Embedded the bolt in the guy's neck or shoulder. That's a confidence builder in the brand, if I ever saw one. True testament to the quality of the $hit they offer, too. Get some! Edited October 21, 2014 by 98Z5V Quote Link to comment Share on other sites More sharing options...

Dane Armory Posted October 21, 2014 Report Share Posted October 21, 2014 (edited) Check your gas block/tube by using airfrom an air hose or a can, put a fired. Brass shell in the chamber and blow it thur the gas tube end inside the upper reciever. Make sure you plug the end of the barrel.. if the brass case come out ... That's NOT your problem ! Then check the ejector and extractor. Good Luck. You may need it ! I fixed a Black Thorne rifle once they Loctited so much stuff and didn't tighten anything right. Loose handguard ,replaced ejector spring. Installed springs backwards, gas block wasn't aligned. Took me 3.5 hours to make it right..

FaRKle! Posted October 21, 2014 Report Share Posted October 21, 2014 (edited) Oh God, Blackthorne...My friend's cousin bought one of their .308 stainless uppers. It wouldn't cycle for crap so he asked me to take a look at it.Here's a summary of what I found wrong:-Mis-aligned gas port to barrel extension (gas port was not at TDC).-Mis-aligned clamp on gas block (only about 1/3 of the gas block hole was over the gas port).-Loose gas block screws with no threadlocker.-Undersized gas block (the gas block hole that goes over the gas port was smaller than the gas port).-Poorly machined cam track (the cam pin would get stuck because the track wasn't machined large enough).-Wrong extractor spring (they used a weak AR-15 one with no o-ring, it had very little tension).I ended up having to realign the gas block, put threadlocker on the gas block screws, grind down the cam track a bit, and get a new extractor spring for it. Before that this gun wouldn't cycle 5 rounds in a row before having an FTE.Robocop was with me one of the times I was troubleshooting this upper.I'll echo the "start with the gas system" suggestion. If all is ok there, see if the BCG cycles smoothly by hand (work the action slowly). You should be able to feel any hangups. Also, check your extractor tension. Sometimes your failure to extract can be caused by the extractor letting go too early due to not enough tension. Edited October 21, 2014 by FaRKle!

Big BS Posted October 22, 2014 Author Report Share Posted October 22, 2014 Thanks for the help I have already experienced the extractor finger and pin problem and changed them to dpms part's thinking of doing the same with gas block. Maybe I will do what I was thinking of and change bolt and carrier and recheck head spacing Quote Link to comment Share on other sites More sharing options...

SpookyEng Posted October 25, 2014 Report Share Posted October 25, 2014 I had never heard of these guys, so I went to the website. Misspellings, wrong specs quoted (1/2 x 28 flash hider on a 308) and a bunch of mil spec quoting for standard processes. Why buy from someone like that? I would of sent that biotch back and if they wouldn't give me a refund it's BBB I go. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted October 25, 2014 Report Share Posted October 25, 2014 I think they already have a F on BBB. Can't really get lower than that. Quote Link to comment Share on other sites More sharing options...
arnie Posted October 26, 2014 Report Share Posted October 26, 2014 I have a Black thorne 308 upper and it was very agravating to get it up and running properly . I changed the springs in the extractor and ejector (both were very soft ) and put a new extractor from another bolt head (with an oring over the spring)and it works fine now .The chamber is cut too short so i have to set the shoulder back about .005 more than the die will go so that took grinding the bottom of the die off . Because of this i cant use factory loaded ammo. Quote Link to comment Share on other sites More sharing options...
