    Here's a few pics of the 6 Bulg. ( new ) barrels from Copes after I chopped and re- profiled them to Krink specs. I had to Knurl one of them as the Tula trunnion it was for was about .003 too big for the barrel .

    Nope, nothin new on the twist rate . Have'nt split the barrel piece yet. As I stated in the last post , that was just a mockup to see if everything was in the right location and they were. Shortly after the pics, I stripped it back down to use as a pattern , (or gage) for the other 6 which I will finish tomorrow and ship to the owner.

    More pics soon.

    Finished the mockup today with the Bulgy 74 barrel from Copes. Everything turned out to be in the right location and you can see what you are left with. An empty RSB groove, and the original barrel pin groove which will in most cases require an oversized pin.

    Will post some more pics when the other 6 barrels are finished.

    Here's an update from today....................

     

    Started on the Bulgy 74 barrels today and these 6 will be Krink length. Got the first one done and am going to do a mockup with my parts kit to make sure everything is in the right location before doing the others.

    So, here's some pics of todays progress:

    Thanks NinerRider, I will get some pics over the weekend of the Bulgy 74 barrels cut and contoured to Krink dimensions and post them. I'm also going to cut one of the barrel pieces that I cut off the Bulgys in half lengthways which will reveal the inside of the barrels twist rate. Only problem is that they are only about 7 1/2- 7 3/4 long as I cut the Bulgys 8 1/2 to allow for a finished recrowned 8 5/16 length, so not sure if I'll be able to get a full turn. We'll see..............

    Im doing E.German and Bulgy barrel modifying for those who are considering using them.

    Loner42,

    Have you cut down any krink barrels yet? I am interested in how accuracy is affected with the 8" barrel and 1:8 twist ratio. Rguns may take a while to get these barrels so I would be interested in other options. I have seen E.German virgin barrels for about $100. lately so this would be a cheap way to go.

    Thanks

     

     

     

    No not yet, but I'm gettin ready to go out and start choppin 6 Bulgy 74 pulled barrels that are like new for a member on THE AK FILES. I'd still like to see where all this twist rate info is coming from. I'm an active member on the AKForum and have'nt seen any threads that actually "document" the twist rates. There's been lots of speculation on several forums ,but that's all it is IMHO. The cleaning rod method is not what I would consider as accurate .

    So somebody hurry up and finish a build with a 8 5/16 E.German or Bulgy barrel and get us a range report. I'd like to know as much as anybody.

    Guys 16" barrels have a twist rate ratio of 1:8, krinks need a ratio of 1:6 to stabilize the bullet. Cutting down a 16" barrel will work but accuracy will suffer not to mention fragmentation of the bullet. Best bet is to find a krink barrel which is big money or hope that RGuns new barrels will be quality and designed on krink specs.

     

    Could you post a link or copy & paste where you got this info ?

     

    Thanks.................

  13. Galil top cover on S12?

    Yeah - that's what I'm talking about! I find it interesting that out of three different Galil top covers that were posted, all three have different types of sights. LEO - what did you do for a front sight? I noticed both of you had the left side safety mod - what parts did you use for that (modified stock Galil, or total custom)? I think no matter how much trouble you guys went through to make these - they are the most practicle for real world use with the Galil LH safety, and should shoulder and point as well as a Galil. Very Nice! :super:

     

    If you couldn't figure out - I am a big Galil/Valmet fan!

     

    The 2 topcovers that 7.62m43 and C&S Metall-W posted look like either Galil Hadar.308 covers or Norinco Hunter with the screw tabs cut off............

  20. Question on barrel threading

    in Tech Section

    Posted

    do I need to cut the barrel sleave off, or can I thread right over it with a larger thread, and then re-thread with a 14x1mm left hand thread? If so, does anybody have experience doing it. Does it cause the threads to be sloppy.

     

    And last question, who can rent me the tools to do it or point me to the right place?

     

    Thanks,

    -Lee

     

    I cut the sleeve off my 7.62x39 and then threaded it 14-1LH. I got the tools from dinzagarms.com. IIRC he rents them for ~$20.

     

    +1 On that.

     

    223addict,

    This is the best way to go in your situation. Do NOT try threading it until you get that extension cut off. You will ssrew up your barrel, guaranteed.

    RDSWriter,

    was wondering if you could tell me how you made the chart :

    SBSTesting-InitialTest-1.jpg

     

    I posted a list of ref. dim. for AK Barrels and components above in this forum and would really like to have been able to make it like your chart is done.

    Thanks

    Don't worry about the columns, the information is a good reference. Good Work!

     

     

    Thanks,

    it just bugs me that i can't keep them straight up and down like i had them in Word. I even printed them out and the stayed nice and straight. It must have something to do with margins or something. I'm still a "hunt and peck" typer, so it takes me awhile sometimes to do something like this. Maybe someone who knows how will volunteer to fix it someday.
